PREPARATION
The following preparations are required before disassembling and assembling the camera.
1. Prepare the Jigs, tools and testers. (Refer to the Table of Jigs, tools and testers.)
2. Make the preparation for the digital adjustment. (Refer to the Preparation of digital adj.)
Preparation of Digital Adjustment
[Required equipment]
Programmed software 76180 (for Digital adjustment, contained 95901 P401-00B)
Computer (for Digital adjustment)
CF card 6 pieces (8MB or above)
CF card reader
1. Preparation for the adjustment and confirmation of CF cards (6pcs.)
1) Product FW (Firmware) of *istD (2 pieces): use for service and updating FW
2) Switch function checking
3) Default setting
4) FW version check [ON]: use for service
5) FW version check [OFF]: use for service
2. Installing procedure of the Adjustment Software (Setting of the Computer)
① Turn on the test computer.
② Place the Programmed software of 76180 (95901 P401-00B) into the CD-ROM drive.
③ Copy the [76180] folder from the Programmed software contained in the CD-ROM to [C:
drive] as shown in the picture below.
④ Copy the file from each folder (01~04) of [ModeSET] to each CF card.
[CAUTION] Since the name of all files is same, you should distinguish them by name label etc.
⑤ Copy the file from [GM_FW] to two CF cards (for FW).
[CAUTION] You should use latest firmware whenever creating the CF cards for updating.
⑤ Rename one of two CF cards which were created for updating firmware from [kb321b.bin]
◆ The CF card named [kb321b.bin] should be used for repairing the camera.
◆ The CF card named [fwdc112b.bin] should be used for updating FW of customer’s camera.
to [fwdc112b.bin].

DISASSEMBLY AND ASSEMBLY
Outline of Disassembly and Assembly
1. Caution
1) Be sure to use the conductive mat and wrist strap to prevent static failure of circuits.
2) Do not stress to the connector terminals and flexible boards because they are very delicate
parts. And, we recommend marking to the flexible board before disconnecting them. This will
be helpful to reconnect the flexible board to the connector terminal properly.
