Main Features 7High Brightness mode enhances meter visibility outdoors.

7Accu-Pitch Sign function uses the motion of the meters lights to show when tuning is completed.

7Guitar/Bass mode lets you tune by string number, with support for 7-string guitars and 6-string basses.

7 Flat tuning is supported with Guitar Flat mode, which allows for down tunings up to six semitones below standard pitch.

7 Switching on the tuner automatically mutes the output signal, allowing you to tune without outputting the sound.

How to Use the Tuner 1. Connect the guitar or bass you want to tune to the INPUT jack.

(This switches on the power.)

2. Press the pedal switch to turn the tuner on. The CHECK indicator will light.

3. Play a single note on your guitar or bass, and tune it. The note name or string number closest to the tone being played appears in the display. Tune the instrument so that both Tuning Guide indicators are lit and the center of the meter is lit green. (Cent display) The meter will light farther toward the left as the pitch gets flatter, or farther toward the right as the pitch gets sharper.

* When the Accu-Pitch Sign function is on, the meter lights stream toward the center of the display when stable tuning at the correct pitch is reached.

* The meter behavior described here is when the CENT display is selected (the factory setting). The behavior is different when youve selected the STREAM display.

* The sound from the OUTPUT jack is muted when the tuner is on.

Convenient Functions

Having the Meter Indicate Completion of Tuning (Accu-Pitch Sign function) When the Accu-Pitch Sign function is on, the meter lights stream toward the center of the display when stable tuning at the correct pitch is reached.

1. While holding down the STREAM/CENT button, turn on the power (insert a plug into the INPUT jack).

2. Press the STREAM/CENT button again to toggle the Accu-Pitch Sign function on/off. On: The meter lights stream to the center from the left and right. Off: The meter lights up at the left and right.

* The TU-3 returns to its normal state when several seconds have elapsed without the STREAM/CENT button being pressed.

* This setting remains stored even after the power is turned off.

Changing the Reference Pitch You can adjust the reference pitch over a range of 436445 Hz. * 440 Hz is the factory default.

1. Press the MODE button and STREAM/CENT button simultaneously. The lowest digit of the current reference pitch (e.g., 0 when set to 440 Hz) blinks in the Note Name/String indicator.

2. Press the MODE button or STREAM/CENT button to change the reference pitch. MODE button: Raises the reference pitch by 1 Hz. STREAM/CENT button: Lowers the reference pitch by 1 Hz.

* If you allow several seconds to elapse without pressing the MODE button or STREAM/CENT button, the TU-3 will return to normal operation.

* When you turn on the power, the current reference pitch will be displayed for several seconds.

* This setting remains stored even after the power is turned off.

Changing the Meters Brightness (High Brightness mode) By switching the meter to High Brightness mode, you can increase its visibility when performing outdoors.

To switch to High Brightness mode, hold down the STREAM/CENT button for two seconds or longer. To return to normal brightness, hold down the STREAM/CENT for two seconds or longer once again.

7. INPUT Jack Connect the guitar or bass guitar to be tuned here.

* The INPUT jack doubles as the power switch. Power to the unit is turned on when you plug into the INPUT jack; the power is turned off when the cable is unplugged.

8. OUTPUT Jack Connect an effects processor, guitar amp, or other such device here.

* The output is muted when the tuner is on.

9. BYPASS Jack Connect an effects processor, guitar amp, or other such device here. This jack will always output the signal from the instrument connected to the Input jack. Use this jack if you want to be heard while you tune.

10. Pedal Switch This switch turns the effect on/off.

11. Thumbscrew When this screw is loosened, the pedal will open, allowing you to change the battery. For instructions on changing the battery, refer to Changing the Battery.

12. DC OUT Jack When an AC adapter is used, you can connect a PCS-20A parallel DC cord (optional) to supply power to effects processors and other PSA adaptor-compatible gear.

* Power cannot be supplied from the DC OUT jack when the TU-3 is running on batteries.

* The PSA series includes two different adaptor types; one with a maximum output current of 200 mA (0.2 A) and the other 500 mA (0.5 A). If you use the PCS-20A to supply power to devices that are compatible with PSA adaptors, make sure that the total current consumption of all devices (including the TU-3) does not exceed the maximum output current of the PSA series unit youre using. The maximum output current is listed in the OUTPUT field of the label affixed to the adaptor itself.

13. AC Adaptor Jack Accepts connection of an AC Adaptor (PSA series: optional). By using an AC Adaptor, you can play without being concerned about how much battery power you have left.

* Use only the specified AC adaptor (PSA series), and connect it to an AC outlet of the correct voltage. Do not use any other AC adaptor, since this may cause malfunction.

* We recommend that you keep batteries installed in the unit even if youll be powering it with the AC adaptor. That way, youll be able to continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.

Precautions When Connecting 7 To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.

7 Some connection cables contain resistors. When connection cables with resistors are used, the sound level may be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

7 If youll be using the TU-3 for an extended time, we recommend that you use an AC adaptor.

7Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices. When powering up: Turn on the power to your guitar amp last. When powering down: Turn off the power to your guitar amp first.

7 This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally.

7When operating on battery power only, the units indicator will become dim when battery power gets too low. Replace the battery as soon as possible.

Changing the Battery When the indicator goes dim or no longer lights while the effect is on, it means that the battery must be replaced.

Replace the battery following the steps below. * Please be sure to read the separate sheet USING THE UNIT SAFELY for details

on battery handling.

1. Hold down the pedal and loosen the thumbscrew, then open the pedal upward.

* The pedal can be opened without detaching the thumbscrew completely.

2. Remove the old battery from the battery housing, and remove the snap cord connected to it.

3. Connect the snap cord to the new battery, and place the battery inside the battery housing.

* Be sure to carefully observe the batterys polarity (+ versus -).

4. Slip the coil spring onto the spring base on the back of the pedal, and then close the pedal.

* Carefully avoid getting the snap cord caught in the pedal, coil spring, and battery housing.

5. Finally, insert the thumbscrew into the guide bush hole and fasten it securely.

Storefront Demo Display 1. While holding down the STREAM/CENT button and Pedal

switch, turn the power on (insert a plug into the INPUT jack). The storefront display appears. The storefront display remains until you turn the TU-3s power off and then on again, or until you press the Pedal switch.
