List of Test Items
1. DSP and EEPROM check
2. WAH RANGE volume check
3. DRIVE volume check
4. Pedal calibration
5. BYPASS check
6. CODEC (DAC L ch) check
7. CODEC (DAC R ch) check
8. CODEC (DAC MIX) check
9. CODEC (ADC L ch) check
10. CODEC (ADC R ch) check
11. CODEC (ADC MIX) check
12. Normal waveform check
13. Noise check
14. Battery operation check
Entering the Test Mode
1. Set all the volume knobs to the left.
2. Connect a DC plug to the AC adaptor jack while pressing down the
[MANUAL/MEMORY] button.
(The MEMORY indicator blinks red.)
3. Press the [MANUAL/MEMORY] button twice while it is blinking red
(for 2 seconds).
(The MEMORY indicator lights up green, enabling to enter the first test
item.)
Note: The test mode cannot be entered unless all the volume knobs are set to
the left.
Note: The test mode cannot be entered unless the button is operated while the
indicator is blinking red.
Test Items
1. DSP and EEPROM check
1. After entering the test mode, DSP/EEPRO check is performed
automatically.
(The MANUAL/MEMORY indicator lights up green while checking.)
2. If no problem occurs, the “MANUAL/MEMORY” indicator lights up
yellow after about 5 seconds and the “ON/OFF” indicator lights up red.
3. If any problem is present, the relevant indicator blinks in the following
manner:
4. Input a square wave (2000Hz, 400mVp-p) and check the output
waveform (DSP through) with an oscilloscope.
fig.wave0_45
2. WAH RANGE volume check
1. Input a square wave (2000Hz, 400mVp-p).
2. Turn the volume knob from the lowest position to the center and to the
highest position.
The “MANUAL/MEMORY” indicator should light up, changing the
color from yellow to green and to red, in this order.
3. Operate the volume knob to check that the oscillation of the output
waveform (DSP through) also changes from 0 to 400mVp-p or above.
4. After confirming that the indicator lights up red at the highest volume
position, move on to [DRIVE] volume check.
(In [DRIVE] volume minimum value detection, [WAH RANGE] volume
maximum value detection is also performed. Leave the [WAH RANGE]
volume knob set to the highest position.)
3. DRIVE volume check
1. Test in the same manner as for [WAH RANGE] volume check, and check
how the “MANUAL/MEMORY” indicator behaves as well as how the
output waveform (DSP through) changes.
4. Pedal calibration
1. Press the [MANUAL/MEMORY] button to proceed to the test items in
the pedal calibration mode.
(All indicators go off.)
2. Step down the pedal all the way back and hold it depressed.
Note: Accurate calibration cannot be performed if the pedal is off the base or
depressed beyond that point.
fig.test4-1_30
3. Press the [MANUAL/MEMOY] button and check that the “MEMORY”
indicator lights up red.
Note: If the “MEMORY” indicator blinks red, go back to step 2 and check the
pedal position, and then perform checking again. If the indicator blinks
red each time checking is repeated, it indicates a faulty sensor circuit.
Indicator behavior by error type
MANUAL/MEMORY blinking red: DSP IRAM error
MANUAL/MEMORY blinking yellow: DSP ERAM error
MANUAL/MEMORY blinking green: DSP IPRAM error
ON/OFF blinking red: EEPROM error

4. Release the pedal so that the pedal stops at its initial pedal position.
Note: Accurate calibration cannot be performed if the pedal is off the base or
depressed beyond that point.
fig.test4-2_30
5. Press the [MANUAL/MEMOY] button and check that the “MEMORY”
indicator lights up green.
Note: If the “MEMORY” indicator blinks green, it indicates a faulty sensor
circuit.
6. Step down “the toe side” of the pedal hard and operate the switch on the
toe side.
Then check that the “MEMORY” indicator lights up yellow.
fig.test4-3_30
7. Step down “the heel” of the pedal hard and operate the switch on the heel
side.
Then check that the “MEMORY” indicator lights up red.
Note: Factory Reset is being performed while the indicator is blinking red. Do
not disconnect power from the unit.
fig.test4-4_30
8. When completed, the “MEMORY” indicator lights up yellow, and the
“ON/OFF” indicator lights up red.
5. BYPASS check
1. Set the [TYPE] volume knob to ‘VOICE.’ (The “MEMORY” indictor lights
up red.)
2. Check the output waveform (analog bypass) with an oscilloscope.
fig.wave1_45
6. CODEC (DAC L ch) check
1. Set the [TYPE] volume knob to ‘MO-WAH.’ (The “MEMORY” indictor
lights up green.)
2. Check the output waveform (DSP internal oscillation, L ch) with an
oscilloscope.
fig.wave2_45
7. CODEC (DAC R ch) check
1. Set the [TYPE] volume knob to ‘VO-WAH.’ (The “MEMORY” indictor
lights up red.)
2. Check the output waveform (DSP internal oscillation, R ch) with an
oscilloscope.

11
PW-10(T)
fig.wave2_45
8. CODEC (DAC MIX) check
1. Set the [TYPE] volume knob to ‘CBY-WAH.’ (The “MEMORY” indictor
lights up green.)
2. Check the output waveform (DSP internal oscillation, MIX) with an
oscilloscope.
fig.wave3_45
9. CODEC (ADC L ch) check
1. Input a sine wave (1kHz, -20dBm).
2. Set the [TYPE] volume knob to ‘BASE MIX.’ (The “MEMORY” indictor
lights up red.)
3. Check the output waveform (ADC L ch) with an oscilloscope.
fig.wave4_45
10. CODEC (ADC R ch) check
1. Set the [TYPE] volume knob to ‘ADVANCED.’ (The “MEMORY”
indictor lights up green.)
2. Check the output waveform (ADC R ch) with an oscilloscope.
fig.wave4_45

12
Mar.2002
11. CODEC (ADC MIX) check
1. Input a sine wave (1kHz, +5dBm).
2. Set the [TYPE] volume knob to ‘CUSTOM.’ (The “MEMORY” indictor
lights up red.)
3. Check the output waveform (AF-AD DSP through) with an oscilloscope.
fig.wave5_45
12. Normal waveform check
1. Input a sine wave (200Hz, 400mVp-p).
2. Power off and on the unit again to enter normal operations, and use an
oscilloscope to check the waveform generated when the initial pedal
position is restored.
fig.test4-2_30
fig.wave7_65
3. Step down the pedal and check that the waveform changes smoothly.
4. Check the waveform generated at the pedal position when it stops, using
an oscilloscope.
fig.test4-1_30
fig.wave6_65
5. Press the [MEMORY/MANUAL] button to check the waveform.
fig.wave8_65
13. Noise check
1. Insert a 47 k ohm short plug into the INPUT jack.
2. Set the [TYPE] volume knob to ‘ADVANCED,’ the [WAH RANGE]
volume knob to the central position and the [DRIVE] volume knob to
‘OFF.’
3. Using a noise meter, check that the residual noise level is ‘-87dBm’ or
below.
4. Connect the monitoring speaker and check that no shock noise is
generated.
14. Battery operation check
1. Remove the DC plug and install a battery.
2. Insert a plug into the INPUT jack and check that power can be applied to
the unit.
3. Next, check that the unit operates normally.
This completes the test mode.
