<PWB Adjustments>
1. Setting and confirmation before adjustment
(1) For the adjustment and inspection of the MAIN PWB (PWC-4418) unit, TP9701 and TP9702 should be
short-circuited.
* By this treatment, the action for [6-8. Fan stop detection] is made invalid (disregarded).
If a DC fan or a dummy is used, this short-circuit action is not required.
(2) For the adjustment and inspection of the VIDEO PWB (PWC-4417), or for the adjustment and inspection
using this PWB, the DS connector (73B4V002) to be used for the set Assy should be connected to the DC
connector of the VIDEO PWB (PWC-4417). (If this connection is not made, no signals are generated for the
VIDEO system.)
(3) Confirm that each terminal voltage specified below is kept within the standard range.
