LED200:
Check it to find out the state of the composite power supply PCB is indicated by
flashing at different intervals. For details, see Table 13-601.
VR200:
Turn it to adjust the lamp intensity used when shading auto correction
(FUNCTION>CCD>MAN-ADJ) is executed in service mode. The result is good if
LED201 turns on. Its adjustment range is equal to 3 rotations.
If LED201 does not turn on after a single rotation, try rotating it in the opposite
direction.
LED201:
Check it to find out whether VR200 is correctly adjusted (it should turn on).
