VIDEO MAIN SIGNAL PATH IN REC MODE
Precautions for maintenance of
timer/main C.B.A.
Disconnection of the flexible cable between P7502 and P7901
for maintenance or check of the timer/main C.B.A. without
applying any voltage will cause the loss of the back up +B of
the timer microcomputer. Be sure to apply a voltage of +4.5 V
E
to the connector of P7503 before disconnecting the flexible
cable.
If the back up +B is lost, the CH setting and data of the timer
will be initialized (reset).
