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 76570 (For Digital adjustment, contained CD-R)
Computer (for Digital adjustment)
SD card 6 pieces (8MB or above)
SD card reader or USB cable (I-USB17) … For connecting with PC
1. Prepare SD card (6 pcs) for confirming adjustment
Prepare SD card (6pcs).
(1) For product FW (Firmware) of *istDS (2 pcs) : use for service and updating FW for customer.
(2) For switch test.
(3) For test mode ON.
(4) For test mode OFF.
(5) For Default setting. (Initialize)
2. Installing procedure of the Adjustment Software (Setting of the Computer)
(1) Copy the [76570] folder from the Programmed software contained in the CD-ROM to [C: drive]
as shown in the picture below.
(2) Copy the file from each folder (01~04) of [ModeSET] to each SD card.
[CAUTION] Since the name of all files is same, you should distinguish them by name label etc.
(3) Copy the each file of [kb392b.bin] and [fwdc137b.bin] from [GM_FW] holder to two SD cards
individually.
*[kb392b.bin] should be used for repairing the camera.
*[fwdc137b.bin] should be used for updating FW of customer’s camera.
[CAUTION] You should use latest firmware whenever creating the SD cards for updating.

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) This product is used lead-free solder.
Surface of solder will be white-tinged color. Solder quickly, because melting temperature
is high and so if heat to much, it is possible to damage to PC board.
Soldering iron requirement: The temperature can be adjusted up to 400º and exclusive
use for lead free solder.
Also it is desirable to use antistatic soldering iron.
The temperature for tip of soldering iron must set between 340º ~ 360º for lead free solder.
(3) Do not stress to the connector terminals and flexible boards because they are very delicate
parts.
Pay attention to the connector terminals and flexible boards
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.

*The manner of adjusting is the same as the other MZ-cameras. Adjust the desired value of Y
axis to ±0.
* Front housing must set mirror down position
(1) Positioning 1st mirror: Put the 1st mirror angle (45°) adjusting jig on the camera, and then
adjust the mirror seat so that the adjusting jig touches the mirror without gap.
Tolerance --- X-axis :±15
許容 Y-axis :±10
(2) Positioning 2nd mirror:
Attach the mirror positioning scope and the
2nd mirror angle adjusting jig to the camera,
and then adjust the mirror angle while looking
through the eyepiece lens.
(Refer to below tolerance for positioning scope)
(3) After adjustment is done, apply the super-glue to both B58.
