Thus, this-behavior is normal, and does not indicate a malfunction. OPERATION OFF -j I I-H CHROMATtC (tv~H) Set the MODE SELECT/POWER Switch to LorH. TUNING RANGE < L > B5 < H > = B6 $ At the range of L, TU-12H is available from C1 to B5. At the range of H, TU-12H is available from C2 to B6. In the tuning range from C2 to B5, either position LorH,can be selected, but preferably use the position L. At the position of H, it tends to take longer time to indicate lower tone, and/or have unstable indication. © A = 440 Hz Ï 445 Hz Select the pitch. The TU-12H has the preset pitch, A=440Hz. (Refer to "Selection of pitch") © Microphone Input Produce a (single) tone. a) If tuning the acoustic instrument, put it close to the Microphone. b) If tuning the electronic/electric instrument, connect it to the Input Jack by using a connecting cord. The indicator nearest to that tone will flash. 0 pitch 440 441 442 443 444 445 BATT. | r~l I I I I I Î •C D L CHHOMATSC F G A B pitch 440 441 442 443 444 445 BATT.

(Example 2) If the Indicators above "G" and "#" light simultaneously, it means the tone near "G#" is produced. Tune it referring to mentioned later. Selection of Pitch PITCH 440 441 442 443 444 445 BATT. I -la aaaaa o' E F G A B While you hold the Pitch button down, the Indicator will blink showing that the preset pitch is A=440Hz. PITCH DOWN o o UP ? Select the desired pitch by pressing the UP (or DOWN) button while the Pitch button is held down. The blinking of the Indicator will case when you release the Pitch button. However, the selected pitch will remain until the POWER Switch is turned off. How to check a tone with Meter and Tuning Guide When a tone is produced, the Indicator shows the name of the tone (C~B) and the Meter shows its pitch at the same time. (Example 1) Pitch A=440Hz ► lower just tuned (Example 2) Pitch A=443Hz lower just tuned riA" 1lJ ► -Ul higher higher If you need Pitch of A=430~440Hzor A=445—450Hz, tune the instruments according to the meter of TU-12H, disregarding Tuning Guide Indicators.

(C.~Bs) CHROMATIC H (Cz-Bs) mmn Battery Replacement (9V x 1) If the indicator above B starts flashing during operation, proper tuning function is no longer available. Please replace the battery with a new one. How to replace the battery 1 Remove the lid of the Battery Housing. 2 Take out the battery and separate it from the Battery Connector. 3 Place a new battery. (Be sure that the polarity is correct.) 4 Close the lid securely. Important • If the TU-12H is not to be used for a long time, remove the battery to prevent the trouble caused by battery leakage. AC Adaptor For AC operation, be sure to use the BOSS AC Adaptor PSA-1 20, 220 or 240 depending on the voltage system in your country, and never use one Adaptor for two units simultaneously. Note • If the B indicator starts flashing while the TU-12H is being operated with the AC Adaptor, tuning is not possible. If this happens, turn the TU-12H off, then turn it on again. • When an amplifier is connected to the TU-12H, set the POWER switch of the TU-12H to OFF immediately after tuning is completed to avoid unnecessary consumption of the battery. Moreover, increasing the volume of the amplifier with the TU-12H on may cause noise.
