SERVICE CAUTIONS AND DISASSEMBLY
1.1REPLACEMENT OF FUSE
Before replacing the fuse, the reason why it blew should
be investigated to prevent trouble from spreading. The
malfunction 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.

1.2CARD FIT CABLE
Pay careful attention to the connecting side of the card fit cable. When connecting it, insert it so as to contact the copper
leaf on its edge to the connector's conductive surface as shown
in Fig. 1-3.
When disconnecting the card fit cable, pull the cable stoppers
in the direction of the arrows. To secure the connection, push
the cable stoppers in the reverse direction of the arrows after
inserting the cable.

ELECTRICAL ADJUSTMENTS
To change the setting of adjustment items, use a computer with the adjustment software to change the set value of the EVR for each
adjustment item as well as to store the changed data into the memory of the camera. If any of the following parts is replaced or the
camera needs to adjust settings of itself such as auto white balance, etc., it requires adjustment of the EVR with a computer.

2.1.2 Applicable lens for adjustments
• Manual zoom
• Manual iris
• Filter diameter
The infinity adjustment lens (YTU92001B) is provided with five kinds of screw-in adapters that make it attachable to camera
lenses of five different filter sizes (∅=37, 43, 46, 49 and 52 mm, pitch=0.75 mm each). Use a camera lens whose filter size is any
of the above-mentioned diameters. If is desirable to use a zoom lens that covers the focal length of 20-40 mm (for to the 2/3-inch
image size) or so as an intermediate focal length of its zoom ratio.
• Recommended lens (example)

2.4 NOTES
2.4.1 Installation
To install the adjustment program, perform the following procedure.
1) If you have any programs currently installed in the serial I/O
port, remove them.
2) Insert the adjustment program diskette into a floppy diskette
drive.
3) From Windows 95, select “Run” from the “Start” button
and type “a:\setup (or b:\setup)” depending on which drive
contains the diskette.
4) Follow the instructions on the screen.
2.4.2 How to adjusting the EVR
Click the “䊱” or “䊲” button to the right of the adjustment
items displayed on the screen to adjust EVR to the required
value.
2.4.3 What is “Initial Data”
The initial data loaded at “2.5 INITIALIZE” consists of preset
adjustment values. Therefore, once the adjustment procedure
is started, all adjustment should be done from beginning to the
end. Otherwise, the preset adjustment values would be written
as the adjustment data.
2.4.4 How to write adjusted data to EEPROM in camera
The adjustment values are written in the EEPROM of the camera when you click “YES” from the “Are you sure to write
EEPROM?” message box which is displayed at the end of the
adjustment.
These buttons
If you abort the adjustment in the middle, the adjustment
values in the camera are not changed (the adjustment values which have been set before the start of the adjustment
remain unchanged).
