CAUTION! When handling the circuit boards a grounded bench mat

and a wrist strap must be used to prevent ESD damage.

Carry out the following checks/adjustments when a camera body is

reassembled after a repair.

Note! Point 1 - 7 without camera shell.

1. The camera body focal length is checked by using the gauge V-2229 together with

the ruler and indicator clock. The focal length is 71.40 mm ± 0.03 mm. Adjustment

slots on the chassis and the bottom mechanism plate.

2.* Secure the camera in the gauge V-2229 by the adapter 904759. Check the 45º

mirror angle with the sighting tube. The image seen, should be symmetrical. Adjust,

if necessary, the four supports in the mirror box by using the tools 901046 (front

supports) and 904018 (rear supports).

3.* Check the flatness of the screen. Use the screen adapter V-4705 and the ruler with

the indicator clock. The same measurement should be obtained at all four corners.

Adjust, if necessary, by the four screws (Pos No. 26, page 14:1).

4.* After the screen is correctly levelled the height must also be checked. Use the

collimator V-4151, the screen adapter V-4705 and the microscope V-2236.

The image seen in the microscope should be the red line central between the two

green lines. Recheck the flatness.

5. Use the tool 902658 or V-2075/2151 for checking of the front key angle. Adjust if

necessary. Cocked position 8° - 9° 3 Ncm. Overtravel 12° - 14° 14 Ncm.

6. Temporarily fit the control panel to the camera body and secure it with a piece of

tape. Use the nut driver 903755 or 903474.

7. Connect the camera body to the Service Test System and go through all checks in the

given order according to the 202 menu. Note! Pos. 7:1 to 7:6 can be checked without

sensor head and light source.

7:1 CAMERA STATUS: Make sure all switches are working properly.

Note! If the contact flex has been removed at any time, the timing between the

pre-release switch (PRS) and the mirror must be checked.

Mount the test shell, 905002, with four screws. Fit the exposure gauge V-2354 in

the release button and slowly rotate the micrometer clockwise and observe when the

mirror is released.
