When checking the P.C.B.:

• Reconnect all cables (connectors) that have been

disconnected.

Be sure to use the extension cable for servicing for

the following section.

POWER (1) P.C.B. CB601 – FUNCTION (1) P.C.B. CB307:

MF117350 (17P 350mm)

• When connecting the flat cable, use care for the

polarity.

• The P.C.B. removed from the rear panel does not

work because its grounding is loose. Be sure to

connect the ground of each P.C.B. to the chassis or

GND with a jumper wire or the like.
