SERVICE CAUTIONS AND DISASSEMBLY
1.1 REPLACEMENT OF FUSE
Before replacing the fuse, the reason why it blew should be
investigated to prevent trouble from spreading. The malfunc-
tion should be repaired before replacing the fuse.
When replacing the fuse, make sure to disconnect the power
supply from the camera beforehand and to replace it with new
one of the specified part number for safety and protection of
the set.
1) Remove two screws 1, and then open the rear panel A and
escutcheon B.

When replacing a fuse, make sure to use new one of the speci-
fied part number for safety and protection of the set.

When disconnecting the card fit cable, pull the cable stoppers
in the direction of the arrows. To secure the connection, push
