How to Enter Test Mode
Set all volume controls at their minimum positions.
Connect a DC plug to the adapter jack while pressing the pedal.
“CHECK” (amber) lights up, and you are in Test mode.
fig.test-dsp_50
500 mV/DIV, 1 mS/DIV
If “CHECK” LED (green) is lit, you are already in the next step of testing.
* If “CHECK” LED (red) blinks, operation stops, and you cannot go to the next
step.Possible causes include defect related to the DSP or CPU, and defective
soldering.Remove the DC plug from the adapter jack, and turn off the power of
the machine.
2. RES Volume Check(LED check
included)
Turn the volume control from the minimum position to the middle and
then to the maximum position clockwise. The “CHECK” LED changes
from green to amber, and then to green.
When the volume control reaches the maximum position, “CHECK”
(green) light up, and the MANUAL volume check starts automatically.
You cannot enter Test mode unless all the volume controls are at their
minimum
positions. You cannot enter Test mode if the minimum values of all the volume
controls are not detected due to some defect or other cause.
As for how to test only a specific item skipping other test items, refer to “5.
How to Test a Specific Item Only” described below after contents of tests are
explained.
Contents of Tests
1. Check of DSP and CPU
Release pedal.
The system checks the DSP and CPU automatically. “CHECK” LED
(green) lights up if no problem is found; “CHECK” (red) blinks if an error
is found.
Check waveforms output from both OUTPUTs A and B on the
oscilloscope.
Input square waves (200 Hz, 1 Vp-p) into GUITAR IN from the oscillator,
and check that the same square waves (200 Hz, 1 Vp-p, DSP through) as
shown in the figure are output.
* The maximum RES volume value and the minimum MANUAL volume value
are detected at the same time.Check the RES volume with the MANUAL volume
control at the minimum position.
3. MANUAL Volume Check (LED check
included)
Turn the volume control from the minimum position to the middle and
then to the maximum position clockwise. The “CHECK” LED changes
from green to amber, and then to green.
When the volume control reaches at maximum position, “CHECK”
(green) lights up, and the DEPTH volume check starts automatically.
The maximum MANUAL volume value and the minimum DEPTH volume
value are detected at the same time. Check MANUAL volume with the DEPTH
volume control at the minimum position.
4. DEPTH Volume Check(LED check
included)
Turn the volume control from the minimum position to the middle and
then to the maximum position clockwise. The “CHECK” LED changes
from green to amber, and then to green.
When the volume control reaches the maximum position, “CHECK”
(green) lights up, and the RATE volume check starts automatically.
The maximum DEPTH volume value and the minimum RATE volume value
are detected at the same time. Check DEPTH volume with the RATE volume
control at the minimum position.

Turn the volume control from the minimum position to the middle and
then to the maximum position clockwise. The “CHECK” LED changes
from green to amber, and then to green.
When the volume control reaches the maximum position, “CHECK “
(green)lights up.
6. CODEC (DAC) Check(Check of MODE
volume and jack-switch included)
Position MODE volume at “GATE/PAN”.
Check that “CHECK” LED (amber) is lit.
Connect a plug to GUITAR IN. (Waves are output even if no signal is
input.)
Check the waveforms output from both OUTPUTs A and B on the
oscilloscope.
Check that the output waveforms are the same square waves (200 Hz, 1
Vp-p) as those shown in the figure.
fig.test-dac_50
Check that the output waveforms are the same step-like waves (1Vp-p) as
those shown in the figure.

500 mV/DIV, 1 mS/DIV
7. CODEC (ADC) Lch Check (MODE
volume check included)
Set MODE volume at “STANDARD”.
Check that “CHECK” LED (green) is lit.
Input 1kHz, -20dB sine waves into BASS IN from the oscillator.
Check the waveforms output from both OUTPUTs A and B on the
oscilloscope.
Check that the output waveforms are the same as those shown in the
figure.
500mV/DIV, 1mS/DIV
To check the GUITAR IN jack-switch, remove the plug from GUITAR IN
and connect it to BASS IN.
Check the waveforms output from both OUTPUTs A and B on the
oscilloscope.Check that the output waveforms are the same square waves
(400 Hz, 1 Vp-p) as those shown in the figure.
fig.test-bassin_50
500 mV/DIV, 1 mS/DIV
To check the OUTPUT B jack-switch, remove the plug from OUTPUT B.
Check the waveforms output from OUTPUT A on the oscilloscope.
fig.test-lch_50
OUTPUT A : 50mV/DIV, OUTPUT B : 500mV/
DIV, 1mS/DIV
Measure the output levels of both OUTPUTs A and B with a noise meter
(JIS-A).
Check that the output from OUTPUT A is between -22.5 dbm and -20.5
dBm, and the output from OUTPUT B is -100 dBm or lower.
8. CODEC (ADC) Rch Check(Check of
MODE volume and battery operation
included)
Set MODE volume at “ULTRA”.
Check that “CHECK” LED (amber) is lit.
Input 1kHz, -20dB sine waves into BASS IN from the oscillator.

BF-3T
Check the waveforms output from both OUTPUTs A and B on the
oscilloscope.
Check that the output waveforms are the same as those shown in the
figure and that they are not distorted.
fig.test-lch_50
OUTPUT A : 50 mV/DIV, OUTPUT B : 500 mV/
DIV, 1mS/DIV
Measure the output levels of both OUTPUTs A and B with a noise meter
(JIS-A).
Check that the output levels are the same as those shown in Test Item 7
above.
Remove the DC plug quickly from the adapter jack, and check battery
operation.
How to Exit Test Mode
Press the pedal to exit Test mode.
During volume checks 2 through 5, however, you exit volume check if
you press the pedal.
Press the pedal again to exit Test mode.
If an error is found during the DSP or CPU check mentioned in Test Item 1
above, you cannot exit Test mode by pressing the pedal. Remove the DC plug
from the adapter jack, and turn off the power of the machine.
The noise check mentioned in “9. Noise check” above is not done in
Test mode, it is done in Normal mode.
How to Test a Specific Item Only
Enter Test mode.
Release pedal. The system checks the DSP and CPU automatically as
mentioned in “1. Check of DSP and CPU” above. The “CHECK” LED
(green) light up if no problem is found.
Choose the next test item you want with MODE volume.
MOMENTARY: 2. - 5. Volume check
GATE/PAN: 6. CODEC(DAC)check
STANDARD: 7. CODEC(ADC)L ch check
ULTRA: 8. CODEC(ADC)R ch check
Remove the plug quickly, or the machine will be reset. If the machine is reset
every time you remove the plug, the adapter jack contact or some other part
may be defective.
Check that the same waveforms are output and that “CHECK” LED (red)
is lit.
If the battery is exhauted, LED will light up gloomily.
Check again that the output waveforms are not distorted.
Remove the plug from BASS IN, and check that the “CHECK” LED goes
out with no waveforms shown (power off).
9. Noise Check
Connect a DC plug to the adapter jack, and a 47 k? short-plug to GUITAR
IN.
Set all the volume controls at to their maximum positions.
Check that “CHECK” LED (red) is lit.
Measure the residual noise of both OUTPUTs A and B with a noise meter
(JIS-A).
Check that the noise is -92 dBm or lower.
Press the pedal to turn off the “CHECK” LED (to form a bypass).
Measure the residual noise of both OUTPUTs A and B with a noise meter
(JIS-A).
Check that the noise is -100 dBm or lower.
Connect a monitor speaker to OUTPUT.
Drop the machine twice from a height of 10 cm to apply it shock.
Check that no abnormal noise occurs.
Turn the pedal on and off and turn each volume control, then check that
no abnormal noise occurs.
You can only do a volume check in the following order: RES -> MANUAL ->
DEPTH -> RATE.
If you do the noise check mentioned in “9. Noise check” above, don’t enter Test
mode, but do it in Normal mode after turning on the power of the machine.
Be sure to check all the test items before you ask for repair or when you check
and service the machine.
