(See Fig.17.)
(4) Disconnect the amplifier 1 board from the bridge board in
the direction of the arrow while releasing the claw
k
of the
connector
CN201
on the bridge board. (See Fig.18.)
Note:
When releasing the claws (
j
,
k
), take care not to break
them. (See Figs.17 and 18.)
(5) Take out the amplifier 1 board and amplifier 2 board togeth-
er from the main body.
