5.
Starting at the REVERB ONLY position, slowly turn clockwise, one click
at a time, to make one full turn (i.e., returning to the "REVERB ONLY"
position).
* To conduct the testing correctly, first set MODE SELECTOR at the 1 position.
Next, turn MODE SELECTOR to the REVERB ONLY position, then execute
the test.
• The LEDs light up in the sequence shown below as the MODE
SELECTOR control is being turned.

Turn MODE SELECTOR in the direction opposite that of step 5 (i.e., turn
it counterclockwise).
Starting at the REVERB ONLY position, slowly turn counterclockwise,
one click at a time, to make one full turn (i.e., returning to the REVERB
ONLY position).
• The LEDs light up in the sequence shown below as the MODE
SELECTOR control is being turned.

If the volume check ends normally, execution automatically advances to
the next test.
* The leftmost Virtual Tape Display LED flashes for 1 second, then remains
steadily illuminated.

4. EXP Pedal Check
1.
Set the MIN volume on the EV-5 to 0.
2.
Depress the heel end of the EV-5 pedal.
3.
Connect the EV-5 to the "EXP PEDAL" jack.
4.
Slowly depress the toe end of the EV-5 pedal.
5.
Verify that the "Virtual Tape Display" LEDs smoothly light up
successively.
If all Virtual Tape Display LEDs light up and EXP (expression) pedal
verification ends normally, execution automatically advances to the next
test. (The EFFECT ON/OFF LED flashes for 1 second, then remains
steadily illuminated.)
* Detach the EV-5 from the RE-20's EXP PEDAL jack.
5. DIRECT Type Selector Switch Check
Verify that the DIRECT switch on the back of the unit is functioning correctly.
• DIRECT type switch: OFF
EFFECT ON/OFF only illuminated
1.
Switch the DIRECT type switch to ON.
Verify that only the TAP LED lights up.
2.
Switch the DIRECT type switch to OFF.
Verify that only the EFFECT ON/OFF LED lights up.
3.
Switch the DIRECT type switch to ON.
Verify that only the TAP LED lights up.
If the check of the DIRECT type selector switch ends normally, execution
automatically advances to the next test.
* After the TAP LED goes dark, the rightmost Virtual Tape Display LED remains
steadily illuminated.
6. ANALOG BYPASS Waveform Check
1.
Input a signal to only INPUT A (MONO).
• INPUT A (MONO): Rectangular wave -- 200 Hz, 500 mVp-p
• INPUT B: No connection
• OUTPUT A (MONO): Oscilloscope channel 1
• OUTPUT B: Oscilloscope channel 2
2.
Adjust INPUT VOLUME to the maximum setting.
3.
Verify that the waveform shown below is output.
fig.check001.eps_48
500 mV/DIV,1 ms/DIV
* Thereafter, make the settings for OUTPUT A (MONO): channel 1 and
OUTPUT B: channel 2, and for the waveform image, set the upper section to
channel 1 and the lower section to channel 2.
