1-1-2. Preparations
Note 1:
For details of how remove the cabinet and boards, refer to “2.
DISASSEMBLY”.
Note 2:
When performing only the adjustments, the lens block and boards
need not be disassembled.
1)
Connect the equipment for adjustments according to Fig. 5-1-5.
2)
Connect the Adjustment remote commander to PK-45 board
CN701 via CPC-12 jig (J-6082-436-A). (See Fig. 5-1-3.)
3)
The shutter button (RL-52 board) is need not be connected. To
remove it, disconnect the following connectors.
FC-67 board CN702 (7P, 1.0mm)
4)
The ST block (Electronic viewfinder, FLASH UNIT and MIC
UNIT) is need not be connected except during “Strobe White
Balance Adjustment” and “Strobe Light Level and White
Balance Check”. To remove, disconnect the following
connectors.
1. FC-67 board CN001 (5P, 1.0mm)
2. FC-67 board CN704 (13P, 1.0mm)
3. FC-67 board CN601 (21P, 0.5mm)
Note 3:
As disconnecting the FC-67 board CN602 means disconnecting
the lithium 3V power supply (PK-45 board BH701), data such as
date, time, user-set menus will be lost. After completing
adjustments, reset these data. If the FC-67 board CN602 has been
disconnected, the self-diagnosis data will be lost. Before
disconnecting, note down the self-diagnosis data (data of page: 3,
address: 2A to 3C). (Refer to “SELF-DIAGNOSIS FUNCTION”
and “5-4.Service Mode” for the self-diagnosis data.)
Note 4:
Setting the “Forced Camera Power ON” Mode
1) Select page: 0, address: 01, and set data: 01.
2) Select page: F, address: 10, set data: 01, and press the PAUSE
button of the adjustment remote commander.
The above procedure will enable the camera power to be turned
on. After completing adjustments, be sure to exit the “Forced
Camera Power ON Mode”.
Note 5:
Exiting the “Forced Camera Power ON” Mode
1) Select page: 0, address: 01, and set data: 01.

3) Select page: 0, address: 01, and set data: 00.
1-1-3. Discharging of the flashlight power supply
The capacitor which is used as power supply of flashlight is charged
with 200V to 300V voltage. Discharge this voltage before starting
adjustments in order to protect service engineers from electric shock
during adjustment.
Discharge procedure
1.
Press the FLASH button (PK-45 board S703) and turn off the
FLASH LED (PK-45 board D702).
2.
Fabricate the discharging jig as shown in Fig. 5-1-4 locally by
yourself. Connect the discharging jig to the positive (+) and
negative (-) terminal of the flash voltage charge capacitor. Allow
ten seconds to discharge the voltage.
