TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS This clock is able to receive the time calibration signal transmitted from

Rugby, England. Signal reception is possible within approximately 1,000 km of the transmitter.

Even when the clock is within the reception range, signal reception is impossible if the signal is blocked by mountains or other geological formations between the clock and signal source.

Signal reception is affected by weather, atmospheric conditions, and seasonal changes.

The time calibration signal is bounced off the ionosphere. Because of this, such factors as changes in the reflectivity of the ionosphere, as well as movement of the ionosphere to higher altitudes due to seasonal atmosaheric changes or the time of day may change the reception range of the signal and make reception temporarily impossible.

Reception is best when the back of the clock is facing toward Rugby. Note, however, that moving the clock while the time calibration signal receive operation is taking place will make stable reception impossible.

Think of the clock as acting like a TV or radio when it is receiving the calibration signal.When receiving indoors, move to a location as near as possible to a window. Proper signal reception can be difficult or even impossible under the conditions listed below.

Rugby1,000 kilometers

500 kilometers

Inside, among buildings, or near neon signs

Inside a vehicle Near refrigerators or other household appliances, near office equipment, mobile phones or wireless LAN devices.

Near a construction site, airport, or other sources of electrical noise, underground or in tunnels, near railroads, highways, or radio stations with interfering frequencies.

Near high-tension power lines

Among or behind mountains

Signal reception is normally better at night than during the day. Radio interference can make signal reception impossible. Strong electrostatic charge can result in the wrong time being set. The alarm does not operate during signal reception.

USING THE CLOCK Any of the following procedures can be used to set current date and time. Auto receive of the time calibration signal Manual receive of the time calibration signal Manual setting without using the time calibration signal

Auto Receive The clock receives the time calibration signal eight times each day (1:00, 4:00, 7:00, 10:00, 13:00, 16:00, 19:00,

22:00). A signal receive operation takes from two to ten minutes under good signal conditions. A receive indicator shows the current status of the receive operation.

Antenna Icon Receive in progress: Icon flashes Receive failed: Icon not displayed Receive successful: Icon displayed

Wave OK Indicator Receive in Progress: OK not displayed All receives over the past 24 hours failed: OK not displayed At least one successful receive over the past 24 hours: OK displayed

Unsuccessful Signal Reception The antenna icon disappears from the display when a signal receive operation is unsuccessful. If this happens, try changing the position or orientation of the clock, and press the WAVE button (4) to receive again.

Manual Receive Press the WAVE button (4) to start a calibration signal receive operation. Use the WAVE button (4) to perform a receive operation after replacing the clocks batteries or if the auto

receive operation was not performed correctly for some reason. The clock beeps and display illumination flashes for about three seconds when a receive operation trigged by the

WAVE button (4) is successful.

Important! Do not perform any button or switch operation while a signal receive operation is in progress. The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data. The DST indicator appears on the display when Daylight Saving Time (summer time) data is received.

Setting the Time and Date Manually When using the clock in an area that is outside of the range of the transmitter in Rugby or in an area where signal

reception is impossible for some reason, you need to manually adjust the time as required. 1. Press the SET button (3) to cycle through the setting screens as shown below.
