1-3. Notes on Replacement of Circuit Board
1-3-1. AT-195 Board, VIF-75 Board and Power Unit (RE-345 Board)
AT-195 board, VIF-75 board, and RE-345 board store the important information including the model name and serial
number.
After replacing the AT-195 board, VIF-75 board, and RE-345 board, perform RESTORE on the [04 <SERIAL
NUMBER>] page of the SERVICE menu. (Refer to “4-2-2. Description of SERVICE Menu”.)

1-4. Cautions when Replacing the Lithium Battery
The lithium battery is installed on the SY-467 board. This lithium battery is used to back up the real-time clock (RTC).
RTC stops operating when the battery life expires. Replace the battery and reset the DATE (M03) of the
MAINTENANCE menu. (Refer to OPERATION MANUAL.)
Part No. Name Usage
!
1-756-134-1X Lithium Battery (ML621 (U)) For internal clock
CAUTION
Ensure that the battery is installed with + and – poles connected to the correct terminals. An incorrect
connection may cause an explosion or leakage of fluid.
1-4-1. Replacing Procedure
Preparation
1. Remove the top cover. (Refer to “2-2. Top Cover”.)
2. Remove the optical cable. (Refer to step 1 in “2-4-1. LEMO Connector Assembly”.)
3. Remove the top chassis. (Refer to step 1 in “2-5. Top Chassis/Air Distributor Assembly”.)
4. Remove the SY-467 board. (Refer to steps 1 and 2 in “2-7. SY-467 Board/AT-195 Board”.)
Procedure

1-5. Cleaning of Connector/Cable
• Lit in two green indicators (right): Receive signal condition is very good.
• Lit in one green indicator (2nd from right): Receive signal condition is OK.
• Lit in one yellow indicator (2nd from left): Receive signal level is weak.
• Lit in one red indicator (left): Receive signal level is severely degraded.
When lit in red, be sure to clean the optical contact portions.
When lit in yellow, cleaning is recommended.
The attenuation of the photo-receptive level may cause transmission error. Clean optical contact portions proceeding as
follows.
The optical contact portion exist in the optical connector on this unit or camera control, and in the optical/electrical
cables.
1-5-1. When the Optical Connector Cleaner (Commercially Available) is
Available
Fixtures
• Optical connector cleaner (commercially available)
-Product name: CLETOP ®
- 14100402 or 14100403 or equivalent (stick type)
- 14100402: 2.0 mm
- 14100403: 2.0/2.5 mm double ended
Tip
• Alcohol is not necessary during cleaning.
• Number of possible wipes is one cleaning per a piece. Do not reuse it.
Cleaning Procedure
Male connector
Clean the tip of the optical contacts (white) using the optical connector cleaner.
Optical contacts (white)
Female connector
1. Insert the optical connector cleaner straight.
2. Apply sufficient pressure (approximately 600 g to 700 g) to ensure that the optical contact is a little depressed.

3. While pressing the optical connector cleaner against the tip of the optical contact, rotate the optical connector
cleaner by 4 to 5 turns clockwise. Holding the optical connector cleaner at around its support facilitates to apply
the pressure.

1-5-2. When the Optical Connector Cleaner (Commercially Available) is not
Available (Connectors/Cables of LEMO)
Clean the LEMO connectors and cables using the following procedure.
Fixtures
• Alignment sleeve remover HC-001 (for female connector)
Sony Part No. : J-6480-010-A or DCC.91.312.5LA manufactured by LEMO, or equivalent
Note
Insert the shorter nose end when removing/installing the alignment sleeve. This fixture contains shock absorber
portion. Grasp not the shock absorber portion of the remover but the handle in use.

absorber portion
Insert the shorter nose end
Handle
• Alcohol (commercially available)
• Cotton swabs (commercially available)
Note
Use a cotton swab whose diameter is about 4 mm. If a cotton swab whose diameter exceeds 5 mm is used, the
cotton swab cannot be inserted into the end of the connector and the tip of the optical contact cannot be cleaned.
