Measurement Functions Your watch can take barometric pressure, altitude, bearing, and other readings. Its built-in watch faces and applications can use readings for display and other useful functions. Note that this watch is not a special purpose measuring instrument. Readings produced by measurement functions are intended as general reference information only. Compass (Bearing Measurement) For serious mountain climbing and other activities that require accurate bearing readings, take along a highly reliable compass to use in combination with the watchs compass.

Important! Note that accurate compass readings and/or correction will not be possible

in the areas described below. In the vicinity of a permanent magnet (magnetic accessory, etc.), metal

objects, high-voltage wires, aerial wires, or electrical household appliances (TV, computer, cellphone, etc.)

In motor vehicles, on boats, on aircraft, etc. Indoors, especially inside of reinforced concrete structures.

EN-4

Altimeter, Barometer The watchs Altimeter uses a pressure sensor to measure barometric pressure, and then calculates and displays relative altitude based on the measured value. Because of this, readings taken at different times at the same location may produce different altitude values due to changes in temperature, humidity, barometric pressure, and other factors. Also note that values displayed by the watch may be different from elevations indicated for areas where you are located. When using the watchs altimeter while mountain climbing, it is recommended that you perform regular correction in accordance with the local altitude (elevation) indications. Tide Graph (Graphic Display of Tide Information) The Tide Graph feature of your watch is intended to provide a rough image of current tide conditions. Do not use its tide information for navigation purposes. For navigation purposes, be sure to use official tide charts issued by a reliable agency or authority for the area you are navigating.

This watch acquires location information at regular intervals and tracks your route on a map. To conserve battery power, the frequency of GPS information acquisition is normally low. Because of this, the route tracking displayed while you are traveling by car, train, or other higher speed mode of transportation may appear rather rough. Very high-speed transportation may make it impossible to obtain GPS information and display route correctly.

If you want smoother route display, start a data measurement operation with the Activity app. GPS information is acquired more frequently during an Activity app data measurement operation, so this will make the route display smoother.

The watch saves route information, marks, memos, and other data in internal storage. Data is retained as long as memory capacity is available. When memory becomes full, the watch automatically deletes the oldest data to make room for newly recorded data.

(GPS) to correct altitude readings automatically (not supported when the WSD-F10 is connected with an iPhone). Configure the settings below to use this function. Correctly configure the Location setting on the watch and smartphone.

For more information, see step 1 under Preparing the Watch for Outdoor Use.

Select ON for the Correct Altitude Using Location setting. After reading Common Outdoor Function Settings, perform the operation under Correct Altitude Using Location.

Since the watch displays relative altitude based on changes in barometric pressure, it may display different altitude readings for the same location, or incorrect readings due to changes in the local barometric pressure. Correct Altitude Using Location uses GPS information to correct altitude. Even so, since GPS information generally includes some error, there may be large error between the altitude readings produced by this watch and actual altitudes indicated locally. If you want more accurate altitude readings while climbing or hiking, manually inputting locally indicated altitude values is recommended. After reading Common Outdoor Function Settings, perform the operation under Altitude Calibration.

When taking altitude readings, keep the watch at as stable a temperature as possible. For better accuracy, strap the watch to your wrist for some time before taking readings in order to allow the watchs temperature to stabilize. Changes in pressure sensor temperature can cause measurement error.

EN-31

Altimeter Precautions Do not use this watch while skydiving, hang gliding, paragliding, gyrocopter

flying, glider flying, or engaged in other activities where altitude changes suddenly.

Altitude readings produced by this watch are not intended for special- purpose or industrial level use.

In an aircraft, the watch measures the in-cabin pressurized air pressure, so readings will not match altitudes announced by the crew.

Large changes in barometric pressure due to atmospheric conditions, large temperature changes, or subjecting the watch to strong impact may make correct readings impossible.

Displayed Altitude Values (Relative Altitude) The two ways to express altitude are described below. Relative Altitude:

This is the difference in the altitudes between two locations. Example: Height measured from the ground to the top of a building (A)

Sea Level Altitude (Elevation): Altitude measured from sea level. Example: Height measured from sea level to the top of a building (B)

Sea level Your watchs Altimeter use a pressure sensor to measure barometric pressure, and then calculates and displays relative altitude based on the measured value. The altitude values displayed by your watch are based on International Standard Atmosphere (ISA) relative altitude data defined by the International Civil Aviation Organization (ICAO).

EN-32

Using Barometer Barometer has a color display Barometer Screen (left), a color display Barometric Pressure Graph Screen (center), and a monochrome display (right).

All of the screens show the barometric pressure at your current location. The Barometric Pressure Graph Screen shows a graph of pressure

changes over the past 24 hours, along with the low pressure (Min) and high pressure (Max) during that period.

The upper part of the monochrome display shows a graph of barometric pressure changes over the past 23 hours.

Your watch measures barometric pressure within the range of 260 to 1,100 hPa (or 7.6 to 32.5 inHg), in units of 1 hPa (or 0.1 inHg).

Calibrating Barometric Pressure Readings Manually Though the pressure sensor built into the watch is adjusted at the factory and normally does not require calibration, you can perform the calibration operation above if you notice that readings are very different from those from other sources. After reading Common Outdoor Function Settings, perform the operation under Barometric Pressure Calibration. Barometer Precautions The barometric pressure graph produced by this watch can be used to

obtain an idea of upcoming weather conditions. Note that this graph provides only a rough idea of barometric pressure trends, and it is not intended for official weather predictions or reporting activities.

Pressure sensor readings can be affected by sudden changes in temperature. Because of this, there may be some error in the readings produced by the watch.

EN-33

Using Sunrise/Sunset Sunrise/Sunset has a color display Time Screen (left), a color display Azimuth Screen (center), and a monochrome display (right).

The Time Screen shows the following times: sunrise time (upper left), pre- dawn nautical twilight start time (lower left), sunset time (upper right), post- sunset nautical twilight end time (lower right), and the current time (bottom center).

The Azimuth Screen shows the current time, the sunrise time, and the sunset time. The outer circumference of the display shows a compass, with a red pointer indicating north. indicates the sunrise azimuth while indicates the sunset azimuth.

The monochrome display alternates at 10-second intervals between sunrise time (RISE) and sunset time (SET).

Nautical Twilight Twilight is the time when the sky brightens as the sun is at or just below the horizon (water horizon or visible horizon). There are actually three types of twilight: nautical twilight, civil twilight, and astronomical twilight. Nautical twilight is normally defined as occurring when the sun is from 6 to 12 degrees below the horizon.

EN-34

Using Tide Graph Tide Graph a color display Tide Graph Screen (left), a color display Fishing Time Screen (center), and a monochrome display (right).

The Tide Graph Screen shows the current tide level and time (red characters in the center of the screen), along with the high tide (High) and the low tide (Low) that will occur up to 12 hours later. The graph shows changes in the tide level for 24 hours (12 hours before and after the current time).

The number of white fish marks on the Fishing Time Screen indicates the projected probability of fishing success. Anywhere from zero to four white fish marks are displayed, and more white fish marks indicate that better success can be expected. Note however, that this in no way specifically guarantees your fishing success.

The monochrome display alternates at 10-second intervals between high tide time (HIGH) and low tide time (LOW).

Before Using Tide Graph To use the Tide Graph Screen, you need to specify the point (port) whose

tide information you want to view. After reading Common Outdoor Function Settings, perform the operation under Port setting.

The information the watch displays on the Fishing Time Screen is calculated based on your current location. It is not affected by the watchs point (port) setting. This means that Fishing Time Screen information can be used for both saltwater and fresh water fishing.

Keep in mind that the Tide Graph Screen shows information about the currently selected point (port), while Fishing Time Screen information is based on your current location.

EN-35

Using My Graph My Graph shows the status of your activities for the current day.

Under initial default settings, both screens show how many calories you have burned from the start (00:00) of the current day.

A color display shows what types of activities you have performed on the current day as a concentric circle graph. Values at the bottom of the screen show the cumulative times spent engaged in each type of activity ( : Riding, : Resting, : Walking, : Running).

You can hide the current time and cumulative activity times by tapping the touch screen of the color display. Tap the touch screen again to show the times.

Before Using My Graph My Graph cannot be displayed under the watchs initial default configuration. To display it, you need to change the Save daily activity records setting to ON. For more accurate burned calorie calculation, you need to input the following information: height, weight, wrist where you wear the watch. After reading Common Outdoor Function Settings, configure the following settings: Save daily activity records, Height, Weight, Wrist where you wear the watch.

EN-36

To specify the type of values shown in the center of the My Graph screen 1. Swipe the touch screen from right to left. On the

Settings Screen that appears, tap D. This displays the setting menu.

2. Scroll the setting menu upwards and downwards. When Centered value / My Graph is displayed, tap it. This displays a list of value types.

3. Scroll the list upwards and downwards. When the type of value you want shown in the center of the My Graph Screen is displayed, tap it. Important!

The setting procedure and calculation method used to determine calories burned, number of steps, and other numeric values depends on the app being used. Because of this, there may be some variation between values. For example, the number of calories shown on My Graph will not necessarily match the number of calories burned on another apps display.

The activity type and activity time displayed by My Graph are based on movements detected by the watchs sensors. Because of this, certain movements may result in misinterpretation of your activity, resulting in the wrong activity type and/or activity time being displayed.

EN-37

Important! Note the precautions in this section whenever using this watch.

Precautions During Use Display Information Accuracy Tide Graph Precautions For Japan area oceans, tide times and level changes are predictively calculated using harmonic constant data obtained from Bibliography 742 Tidal Harmonic Constants Tables, Japanese Coast (February 1992) published by the Hydrographic Department of the Japan Coast Guard, and from the List of Tidal Stations (2015) published by the Japan Meteorological Agency. For other area oceans, tide times and level changes are predictively calculated using harmonic constant data obtained from NOAA, NOAA CO- OPS, and the NOAA Tides & Currents website, and the U.S. DEPARTMENT OF COMMERCE / COAST AND GEODETIC SURVEY January 1942 TH-1. Actual tidal phenomena fluctuate in accordance with weather, the season, and various other factors, and may give rise to irregularities not in accordance with calculated values. Certain conditions may result in some deviation from actual tides. Because of this, the information produced by the Tide Graph function of this app and watch should be treated as approximate reference information only. Never use it for navigation or any other decisions about tide that may put safety at risk. Sunrise/Sunset Precautions Sunrise and sunset calculations are performed using the following azimuths: North: 0 degrees, East: 90 degrees, South: 180 degrees, West: 270 degrees. Calculation results include error of multiple seconds, and error becomes greater at higher latitudes. Calculations assume a level horizon, and local topography is not taken into consideration.

EN-68

Moon Age Precautions Moon ages displayed by this watch are based on the calculation described below. (1) Elongation is calculated using solar and lunar coordinates produced by functional calculus. (2) Moon age is calculated based on the correlation between the elongation and average moon age. Though the lunar period averages 29.53 days, it actually fluctuates by as much as 1 day, so this calculation produces an error of up to 1 day. Water Resistance This watch is water resistant up to five atmospheres, which means it can be worn while working around water and while swimming. However, note the information below. Even if a watch is water resistant, note the usage precautions described

below. Avoid using this watch while windsurfing, skin diving, or scuba diving. Do not operate the buttons while your watch is submersed in water or

wet. Do not charge the watch while it is in water or wet. Avoid wearing your watch while in the bath. Do not wear your watch while in a heated swimming pool, sauna, or any

other high temperature/high humidity environment. Do not wear this watch while washing your hands or face, or while

performing any other task that includes the use of soap or detergent. The touch screen does not work while the watch is submerged in water. After using the watch where it is submerged in seawater or fresh water, or

where it is soiled by sand or mud, rinse it with clean water as described below and then thoroughly dry it. 1. Fill a bucket or other container with tap water or other clean water. 2. Place the watch in the water and leave it there for about 10 minutes. 3. Gently move the watch back and forth in the water to remove any salt,

dirt, mud, sand, etc. If the touch screen is dirty, do not rub it without first washing it clean. After washing the watch, use a clean, dry, soft cloth to wipe away any

remaining water. Next, leave the watch in a well-ventilated, shaded location to dry thoroughly.

To maintain water resistance, have the gaskets of your watch replaced periodically (about once every two or three years).

Be sure to leave battery replacement up to an authorized CASIO service center or your original retailer. Unauthorized battery replacement may cause problems with the waterproof performance of the watch.

EN-69

The inside surface of the watch glass may fog when the watch is exposed to a sudden drop in temperature. No problem is indicated if the fogging clears up relatively quickly. Sudden and extreme temperature changes (such as coming into an air conditioned room in the summer and standing close to an air conditioner outlet, or leaving a heated room in the winter and allowing your watch to come into contact with snow) can cause it to take longer for glass fogging to clear up. If glass fogging does not clear up or if you notice moisture inside of the glass, immediately stop using your watch and take it to an authorized CASIO service center or to your original retailer.

Do not charge the watch if the watch or charger cable is wet. Wipe off all moisture and make sure the watch and charger cable are dry before charging.

Using GPS (WSD-F20 series only) You watch can use radio signals from Global Positioning System satellites to determine your current location and the current time anywhere on the globe. The process for determining your current location is called positioning.

Appropriate and Inappropriate Signal Reception Location A good location for signal reception is outdoors where the sky is visible and

not blocked by buildings, trees, or other objects. You may experience GPS signal reception problems in the areas described

below. Where the view of the sky above is narrow Near trees or buildings Near a train station, airport, or other congested area, or where there is a

large amount of vehicular traffic Near railway aerial wires, high-voltage lines, TV towers, etc.

GPS signal reception is not possible in the areas described below. Where the sky is not visible Underground, in a tunnel, underwater Indoors (Reception may be possible near a window.) Near wireless communication equipment or other devices that generate

electromagnetism. GPS satellites are in constant motion, so your location, the time of day, or

other factors may cause a delay in the positioning operation or may even make positioning impossible.

EN-70

Using GPS Outside Your Country Some countries or geographic areas put legal restrictions on the use of GPS, on the collection and logging of location information, etc. Your watch has built- in GPS functionality, so before embarking on international travel to a country or area outside of the country where you purchased your watch, you should check with the embassy of the countries you plan to visit, your travel agency, or some other reliable source of information to find out if there are any prohibitions or restrictions on bringing in devices with GPS functionality, or on the logging of location information, etc. Long Periods of Non-use If you allow the watch to remain discharged and unused for a long period, it will take a long time to acquire GPS signals and perform positioning immediately after you charge the watch and start using it again. GPS Function Precautions Whenever you are in any area where radio wave reception is prohibited or

restricted, perform the operation below to turn off the Location setting. 1. While the watch face is displayed, swipe the touch screen from top to

bottom and then tap D. 2. Scroll downwards and tap Connectivity and then Location. 3. On the screen that appears, disable Location.

Protective stickers Be sure to remove all protective stickers and/or paper tags that may be

affixed to your watch (including its back cover) and/or its band when you purchase it. Using the watch without removing protective stickers and/or paper tags may result in the build-up of dirt between the watch/band and the sticker/paper tag, which creates the risk of rust and skin rash.

Charging The watch and AC adaptor may become warm to the touch during charging.

This is normal and does not indicate malfunction. Do not charge the watch while its charge level is high enough for watch

operation. Waiting until the charge level is low until you charge will help to extend battery life. Any of the following can hasten battery deterioration and should be avoided. Frequent charging while the battery is fully charged or near fully charged Continually charging while the battery is fully charged or allowing

charging to continue for a long time Connecting and disconnecting the charger cable multiple times during a

single day even though the battery is fully charged Do not charge the watch in a location where large amounts of moisture,

dust, or fine metal particles are present, in a location subjected to vibration, or near a hard line telephone, a TV, a radio, etc.

The charger cable of this watch is magnetic. Contact with sand containing iron particles can make it unusable for charging. Should the charger terminal or cable become soiled with mud or sand, thoroughly wipe off all foreign matter before charging.

In an area where it is extremely cold or hot, you may not be able to charge the watch or the watch may not charge completely. Charge the watch in an area where the ambient temperature is between 10C and 35C (50F and 95F).

EN-73

Band Tightening the band too tightly can cause you to sweat and make it difficult

for air to pass under the band, which can lead to skin irritation. Do not fasten the band too tightly. There should be enough room between the band and your wrist so you can insert your finger.

Deterioration, rust, and other conditions can cause the band to break or come off of your watch, which in turn can cause band pins to fly out of position or to fall out. This creates the risk of your watch falling from your wrist and becoming lost, and also creates the risk of personal injury. Always take good care of your band and keep it clean.

Immediately stop using a band if you ever notice any of the following: loss of band flexibility, band cracks, band discoloration, band looseness, band connecting pin flying or falling out, or any other abnormality. Take your watch to an authorized CASIO service center or to your original retailer for inspection and repair (for which you will be charged) or to have the band replaced (for which you will be charged).

Temperature Never leave your watch on the dashboard of a car, near a heater, or in any

other location that is subject to very high temperatures. Do not leave your watch where it will be exposed to very low temperatures. Doing so can cause malfunction.

Leaving your watch in an area hotter than +60C (140F) for long periods can lead to problems with its LCD. The LCD may become difficult to read at temperatures lower than 0C (32F) and greater than +40C (104F). Watch operation that is stopped due to high temperatures will not resume until watch cools sufficiently. Wait for a while to allow the watch to cool.

Magnetism Some watch functions may not operate normally in a location where

magnetism is present. Very strong magnetism (from medical equipment, etc.) should be avoided because it can cause malfunction of your watch and damage to electronic components.

EN-74

Chemicals Do not allow your watch to come into contact with thinner, gasoline,

solvents, oils, or fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain such ingredients. Doing so can cause discoloration of or damage to the resin case, resin band and other parts.

Storage If you do not plan to use your watch for a long time, thoroughly wipe it free

of all dirt, sweat, and moisture, and store it in a cool, dry place. Disconnect the charger cable from the AC adaptor and unplug the AC

adaptor from the power outlet when not charging. Store them in a safe place for later use. The charger cable is magnetic, so keep it away from magnetic cards, precision equipment, and analog watches.

Resin Components Allowing your watch to remain in contact with other items or storing it

together with other items for long periods while it is wet can cause color on resin components to transfer to the other items, or the color of the other items to transfer to the resin components of your watch. Be sure to dry off your watch thoroughly before storing it and make sure it is not in contact with other items.

Leaving your watch where it is exposed to direct sunlight (ultraviolet rays) for long periods or failure to clean dirt from your watch for long periods can cause it to become discolored.

Friction caused by certain conditions (strong external force, sustained rubbing, impact, etc.) can cause discoloration of painted components.

If there are printed figures on the band, strong rubbing of the printed area can cause discoloration.

Daily use and long-term storage of your watch can lead to deterioration, breaking, or bending of resin components. The extent of such damage depends on usage conditions and storage conditions.

Watch Sensors A watch sensor is a precision instrument. Never try to take it apart. Never

try to insert any objects into the openings of a sensor, and take care to ensure that dirt, dust, or other foreign matter does not get into it. After using your watch where it has been immersed in saltwater, rinse it thoroughly with fresh water.

EN-75

Metal Components Failure to clean dirt from metal components can lead to formation of rust,

even if components are stainless steel or plated. If metal components exposed to sweat or water, wipe thoroughly with a soft, absorbent cloth and then place the watch in a well-ventilated location to dry.

Use a soft toothbrush or similar tool to scrub the metal with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.

Liquid Crystal Display Display figures may be difficult to read when viewed from an angle. The LCD of this watch has flat bottom, and so it is not round. Because of

this using a watch face that is designed for a round display may result in some part of the face being cut off.

The liquid crystal panel of this watch uses high-precision technology that provides a pixel yield in excess of 99.99%. This means that some very small number of pixels may not light or may remain lit at all times. This is due to the characteristics of the liquid crystal panel, and does not indicate malfunction.

EN-76

User Maintenance Caring for Your Watch Remember that you wear your watch next to your skin, just like a piece of clothing. To ensure your watch performs at the level for which it is designed, keep it clean by frequently wiping with a soft cloth to keep your watch and band free of dirt, sweat, water and other foreign matter. Whenever your watch is exposed to sea water or mud, rinse it off with clean

fresh water. For a resin band, wash with water and then wipe dry with a soft cloth. Note

that sometimes a smudge like pattern may appear on the surface of a resin band. This will not have any effect on your skin or clothing. Wipe with a cloth to remove the smudge pattern.

To clean the metal parts on a resin band, use a soft toothbrush or similar tool to scrub the band with a weak solution of water and a mild neutral detergent, or with soapy water. Next, rinse with water to remove all remaining detergent and then wipe dry with a soft absorbent cloth. When washing the band, wrap the watch case with kitchen plastic wrap so it does not come into contact with the detergent or soap.

Dangers of Poor Watch Care Rust Though the metal steel used for your watch is highly rust-resistant, rust can

form if your watch is not cleaned after it becomes dirty. Dirt on your watch can make it impossible for oxygen to come into contact

with the metal, which can lead to breakdown of the oxidization layer on the metal surface and the formation of rust.

Rust can cause sharp areas on metal components and can cause band pins to fly out of position or to fall out. If you ever notice any abnormality immediately stop using your watch and take it to an authorized CASIO service center or to your original retailer.

Even if the surface of the metal appears clean, sweat and rust in crevasses can soil the sleeves of clothing, cause skin irritation, and even interfere with watch performance.

EN-77

Premature Wear Leaving sweat or water on a resin band or bezel, or storing your watch in

an area subject to high moisture can lead to premature wear, cuts, and breaks.

Skin Irritation Individuals with sensitive skin or in poor physical condition may experience

skin irritation when wearing a watch. Such individuals should keep their leather band or resin band particularly clean. Should you ever experience a rash or other skin irritation, immediately remove your watch and contact a skin care professional.

Chargeable Battery Handling (Please recycle!) The built-in lithium-ion battery includes valuable resources. When you are ready to discard your watch, follow proper procedures in order to recycle resources. For information about the proper procedure to follow when discarding the watch, contact an authorized CASIO service center or your original retailer.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power Wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. The WSD-F10/WSD-F20/WSD-F20S/WSD-F20X/ WSD-F20SC/WSD-F20A has been tested and found to comply with FCC/ IC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules.

This product is subject to the Export Administration Regulations (EAR) of the United States, and so it cannot be exported to or brought into countries that fall under U.S. Embargoes and Other Special Controls.
