TD-10M

■ TUNING PROCEDURE

1. Press the POWER switch to turn the power on.
2. When the POWER is switched on, the tuner is set to the Auto Mode and the
previously selected Standard Pitch setting.
* In the Auto Mode, the tuner automatically displays the closest note played by the
instrument and whether that note’s pitch is high or low.
3. To change the Standard Pitch, press the CALIB switch. Each time the switch is
pressed, the Standard Pitch will increase by 1Hz (430 – 449Hz).
4. To tune an electric or electronic instrument, use the contact mic, an external
mic or pickup. Use the INPUT jack to connect the instrument or mic’s cable to
the tuner. (When a plug is connected to the INPUT jack, the internal
microphone does not operate.)
* The contact mic can be used on brass and other similar acoustic instruments. Use
the clip on the contact mic to attach the mic to the instrument (bell or other part of
the instrument that vibrates). The round silicon pad on the clip contains the
pickup mic.
If it is not possible to attach the contact mic to the instrument, use the internal mic
and play the note as close to the mic as possible.
5. When a note is played on the instrument, the tuner automatically selects the
closest note.
* At this time, another note can be manually selected by pressing the NOTE switch
(each time the switch is pressed the note is increased by one-half step :Manual
Mode). Press the AUTO switch to return the tuner to the Auto Mode.
6. Once the selected note is displayed, tune your instrument until the middle
tuning guide (green) lights and the needle of the meter display points to “0”.
