C- 58. INPUT 1 RIM TRIGGER
[Initial indication]
[Test content]
Add looped signal from PHONES to the right side of
IN01 (SNARE) and check that the inputted signal is
being inputted into the CPU at the correct gain. Take
care, however, to cut off DC by installing a capacitor
(approx. 0.1 F) on the signal line (right-hand) side.
[Test method]
Maximize PHONES VR. Connect the looped signal
from PHONES to IN01 (SNARE) using a stereo cable.
[Check item]
Check LCD test results.
[Indication of judgment result]
In case of OK
In case of NG
[Content of FAIL judgment]
In case of NG, no further step will take place.
[Completing the test]

C- 62. TRIGGER SW IN 5
[Initial indication]
[Test content]
Add looped signals to IN2(TOM1) ~ IN5 (TOM4)
from PHONES and check that the trigger switch works
correctly. Take care, however, to cut off DC by
installing a capacitor (approx. 0.1 F) on the signal line
(right-hand) side.
[Test method]
Maximize PHONES VR and put in a looped stereo cable
from PHONES in order from IN2 (TOM1) to IN5
(TOM4). Take care, however, to cut off DC by inserting
a capacitor (approx. 0.1 F) on the signal line (right-hand)
side.
[Indication of judgment result]
Check LCD test results.

[Initial indication]
[Test content]
Set all attenuator switches in the H-position state and put
the signals looped from PHONES in IN01 to IN16. Check
that the signals are being inputted into the CPU with the
correct gain.
[Test method]
Put all attenuation switches at H position and maximize
PHONES VR. Put in a looped cable in order from IN01
to INI16.
[Check item]
Check LCD test results.
[Indication of OK]
If the above appears, connect a cable to IN02 (TOM1).
(Go on to the next test.) Repeat in order until IN16 is
reached and confirmed.
