1. Display the version number
The version number is displayed by the blinking/off combination of the
green and red LEDs of [SELECT], the red LED of [EFX] ON/OFF.
❍
: Blinking
●
: Off.
2. DSP check: (automatically judged)
Press the foot switch once for SELECT switching (white side) during
version display to turn off the LEDs and start automatic checks.
The LEDs come on in the order of green, red of [SELECT] and red of
[EFX] during the checks.
If all the checks are completed and the results are OK, all LEDs blink.
If the results are NG (no good, fail), only the [EFX] LED blinks.
The automatic checks take approximately 5 - 6 seconds.
If the check results are OK, press the foot switch for SELECT switching
(white side) to proceed to the next check.
If the results are NG, the next check cannot be started.
3. Switch check:
When the switch check starts, all LEDs go out.
1.
[SELECT] switch operation check
Press the [SELECT] button.
If the check results are OK, both of the green and red LEDs of [SELECT]
come on.
If the check results are NG, none of the LEDs come on. The next check
cannot be started, either.
2.
Operation check for “AMP TYPE switching” of LEAD rotary switch
Shift the switch slowly in the following order to check if the switch
setting is read correctly.
At this time, check if the green and red LEDs of [SELECT] come on
alternately as follows.
ACOUSTIC (green, red)
→
BLACK PANEL (green)
→
BRIT COMBO
(red)
→
TWEED (green)
→
CLASSIC STACK (red)

METAL STACK

METAL STACK (green)
→
CLASSIC
STACK (red)
→
TWEED (green)
→
BRIT COMBO (red)
→
BLACK
PANEL (green)
→
ACOUSTIC (red)
If the check results are OK, both of the green and red LEDs of [SELECT]
come on.
If the check results are NG, the green and red LEDs do not come on
simultaneously. The next check cannot be started, either.
If the switch knob is shifted too fast, the green and red LEDs blink.
In this case, repeat the operation slowly to allow the switch settings to be read
at all positions.
3.
Jack switch (foot switch terminal [EFX], [RECORDING OUT/PHONES]
terminal) check
a.
Foot switch terminal [EFX] check
Press the foot switch for EFX (red side) on/off switching to check if the
green LED of [SELECT] comes on.
Then disconnect the PCS-31 plug from the [EFX] terminal to check if the
green LED of [SELECT] goes out and the red LED comes on.
Then insert the PCS-31 plug again to check if the green LED of [SELECT]
comes on.
b.
[RECORDING OUT/PHONES] terminal check
Then insert the headphones plug into the [RECORDING OUT/PHONES]
jack to check if the green LED of [SELECT] goes out and the red LED
comes on.
Finally, disconnect the headphones plug.
If the check results are NG, the next check cannot be started.
If the 2. - 4. checks are completed, both of the green and red LEDs of
[SELECT] blink.
After completing the checks, press the foot switch for SELECT switching
(white side) to proceed to the next check.
5. Volume check:
When the volume knob is shifted, the DSP starts self-transmission, and
sound is output from the speaker if connected during the check. The sound
volume varies depending on the position of the knob during the volume
setting reading.
When the volume check starts, all LEDs go out.
The following confirmation is done for the volume check.
Readings of the respective volumes are detected at (1) “0” or “OFF”, (2)
center, and (3) “10” or the maximum position. Check the results by
means of the green LED of [SELECT] as follows.
(1)
Detection at “0” or “OFF” Green LED of [SELECT] goes out.
(2)
Detection at the center Green LED of [SELECT] blinks once.
(3)
Detection at “10” or “maximum” Green LED of [SELECT] comes
on.
Turn the volume knob slowly from position (1) to position (3).
Volume reading for check in (3) is completed.
After the volume reading is completed, the green LED of [SELECT]
remains on and waits for the next check.
The checks are done in the following order.
After each volume check is completed, be sure to keep the knob in position (3)
(all the way clockwise). Otherwise, the next volume check cannot be started.
Order of checks
JC CLEAN [VOLUME]
→
LEAD [GAIN]
→
LEAD [VOLUME]
→
[BASS]
→
[MIDDLE]
→
[TREBLE]
→
[EFX]
→
[REVERB]
If a check is done in the wrong order, the operation is neglected and only the
volume to be checked is detected.
If one of (1) - (3) cannot be detected at the respective volume levels, the next
check cannot be started.
When all VR checks are completed, all LEDs blink.
If all the check results are OK, the green and red LEDs of [SELECT] blink.
This completes the checking process.
Turn off the power.
