Turning on the power
Installing the battery:
1 Lightly press on “A” of the battery compartment in the bottom
panel of the DT-10, and open the lid upward.
2Attach the battery to the battery clip. Make sure that the polarity is
correct.
3Place the battery in the battery compartment, and close the lid.

The battery also backs up the settings, and maintains the calibration
and flat tuning settings. If you remove the battery from the DT-10 or if
the battery runs low, the calibration will be reset to 440 Hz and the flat
tuning setting will be reset to 0. (If an AC adaptor is used with the DT-
10, the settings will not be lost.)
When the battery nears the end of its life, the LED meter and note
display will become darker. Install a new battery as soon as
possible.

1. TUNER ON/OFF switch
Switches the tuner on/off.
This switch is valid if the instrument to be tuned is connected to the
INPUT jack.
2. INPUT jack (mono)
Connect the instrument to be tuned to this jack.
When not using the DT-10, disconnect the cable from this jack to extend
the life of the battery.
3. FLAT key
Specifies a flat tuning (semitone-dropped tuning).
4. CALIB key
Adjusts the calibration between 438-445 Hz.
5. DC power jack (DC 9 V IN)
An AC adaptor (9 V , 50 milliamps or greater) can be connected
to this jack.
6. BYPASS jack (mono)
Connect this jack to your amp etc. The signal from the INPUT jack will
always be output from this jack regardless of the on/off setting of the
tuner.
7. OUTPUT jack (mono)
Connect this jack to your amp etc. The signal from the INPUT jack will
be output from this jack only when the tuner is off. The signal will not
be output when the tuner is on.
8. LED meter
Indicates the difference between the reference pitch and the input sound.
9. FLAT mode LED
This will light if you have specified a flat tuning.
10. Note display
Shows an alphabetical character and a dot (indicating a sharp “#”) to
indicate the note name that is nearest the pitch that is input from the
INPUT jack. This display also shows the calibration or flat tuning
setting at power-on or while you are making the setting.
Connections
Turn off the power of all devices before you make connections.
The INPUT, OUTPUT, and BYPASS jacks are all mono. Stereo
cables cannot be used.

1 Connect a cable from the OUTPUT jack or BYPASS jack to your
amp etc.
OUTPUT jack: Use this jack if you want the sound to be muted while
tuning.
BYPASS jack: Use this jack if you want the sound to always be output,
regardless of whether you are tuning.
2 Connect a cable from the instrument to be tuned to the INPUT
jack.
When you connect a cable to the INPUT jack, the power will be turned
on, and the calibration setting will appear for several seconds in the
note display (lit → blinking). If you have specified a flat tuning (1–7),
the flat tuning setting will also be displayed (lit → blinking) following
the calibration setting.
Connecting a cable to the INPUT jack will turn the power on, but the
tuner will be off. Press the TUNER ON/OFF switch to turn on the
tuner. (☞ “Tuning”)
The input signal is sent to the OUTPUT and BYPASS jacks via a
buffer amp. If a cable is connected to the INPUT jack, the buffer
amp will be consuming the battery regardless of whether the tuner
is on or off. When you are not using the DT-10, we recommend that
you disconnect the cable from the INPUT jack in order to extend
the life of the battery.
Tuning
1 Press the TUNER ON/OFF switch to turn on the tuner.
The LED meter will light.
The TUNER ON/OFF switch is valid only if the instrument to be
tuned is connected to the INPUT jack.
2If necessary, set the calibration and/or flat tuning. (☞ “Adjusting
the calibration,” “Specifying a flat tuning”)
3Play a single note on your instrument.
The note name closest to the note you played will appear in the note
display. If it’s sharp such as A#, the dot will light.

Note name “A”

Note name “A#”
4Tune your instrument so that the desired note name appears.
5 When the note display shows the desired note name, tune your
instrument so that only the center indicator of the LED meter (the 0
position) is lit.
■ Adjusting the calibration
Here's how to adjust the calibration (the reference pitch for tuning,
shown as the middle A note on a piano “A4”). With the factory settings,
this is set to 0: 440 Hz.
1 Press the CALIB key.
The current setting will appear for several seconds in the note display.
2 While the setting is shown in the display, press the CALIB key to
set the calibration.
Each time you press the key you will cycle through the following
settings.
0: 440 Hz 2: 442 Hz 4: 444 Hz 8: 438 Hz
1: 441 Hz 3: 443 Hz 5: 445 Hz 9: 439 Hz
When you have made the desired setting, wait approximately two
seconds without pressing the key.
The indication in the note display will blink three times, and the
calibration setting will be completed. You will then return to tuning
mode.
The calibration setting is remembered even after the cable is
disconnected from the INPUT jack.
■ Specifying a flat tuning
You can specify a dropped tuning in the range of one flat (semitone) to
seven flats (a fifth) lower than standard tuning.
With the factory settings, this is set to 0: off (standard tuning).
1 Press the FLAT key.
The current setting will appear for several seconds in the note display.
2 While the setting is shown in the display, press the FLAT key to
set the flat tuning.
Each time you press the key you will cycle through the following
settings.
0: off (standard tuning) 4: four flats (major third lower)
1: one flat (semitone lower) 5: five flats (perfect fourth lower)
2: two flats (whole tone lower) 6: six flats (tritone lower)
3: three flats (minor third lower) 7: seven flats (perfect fifth lower)
When you have made the desired setting, wait approximately two
seconds without pressing the key.
The indication in the note display will blink two times, and the flat
tune setting will be completed. You will then return to tuning mode.
If a flat tuning has been specified, the FLAT mode LED above the note
display will light.
When tuning, the note display will show a note name that is higher
than the actually-input pitch by the flat tuning setting. (For example if
you have specified a flat tuning of 1, the display will indicate “A#”
when you input an “A” pitch.)
The flat tuning setting is remembered even after the cable is
disconnected from the INPUT jack.
