[Note of Assembly]

[CONF.] Function Check

[NOTE] This confirmation should be done before installing the external parts.
[Required equipment] Regulated DC power supply, Circuit tester, Cable switch CS-205,
Power adaptor (Refer to the table of Jigs, Tools and Testers)
1. Short-circuit the Main SW lands of 0-T100 by soldering as shown in Fig.17.
2. Temporarily install the bottom cover.
3. [CONF.] Set the power source to DC5.5V/3A, and connect the Power adaptor with the
camera. Make sure not exist any shortage or leakage in the circuit.
4. [CONF.] Connect the Cable switch CS-205 with the camera, and then confirm the
operating and displaying for the shutter release, shutter and mirror.
5. After confirmation is done, remove the solder and bottom cover.
Current consumption:
Main SW/on (Light metering: off) ... Less than 380μA
While light metering ... Less than 150mA,
While exposure ... Less than 350mA
2. MAIN P.C. BOARD
[NOTE]
Assemble the Main P.C. board in reverse order of disassembly procedures in accordance with
"Note of assembly".
[Disassembly Procedures]
2-1. 0-J100
1） PT (17x20) x2 (PT: Polyester tape)
2） BT (10x30)
3） 7 lands on 0-J100
4） TY-CNL-G1.7x4.0, M5
5） Remove the adhesive applied 0-J100.
[Note of Assembly]
When replacing 0-J100, stick PT (12x20) on the flexible board.
After installation is done, the following confirmation and adjustments should be
required.
