Part 3: Repair Information
4. Command Dial Tool
To operate the camera without the top cover in place, you should construct this
"Command Dial Tool" by modifying a Top Flex (CHl-6658). Place jumpers between
GND and MAIN 2 and MAIN 3, and jumper GND to X.GND on the Main Flex. Plug
this modified Top Flex into the connector on the main Flex. The camera will now be
in the MANUAL (M) mode.
