Camera body 201F
Checks & Adjustments 3:6
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 - 5 without camera shell.
1. To avoid damage to the coaxial and the ribbon cable, temporarily fit the control
panel to the camera body with a piece of tape.
2. The camera body´s focal length is checked and adjusted by using the tool V-2229.
The focal length is 71.40 mm ± 0.03 mm.
3.* Check the mirror 45° angle using above tool in combination with the sighting tube.
Adjust the four supports in the mirror box by using the tools 901046
(front supports) and 904018 (rear supports).
4. 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.
5. Connect the camera body to the Service Test System and go through all checks in the
given order according to the 201F menu. Note! Point 5:1 to 5:5 can be checked
without sensor head and light source.
5:1 CAMERA STATUS: Make sure all switches are working properly with the speed ring
in C-position.
Note! If the self timer board has been removed at any time, the timing between the
pre-release switch (PRS) and the mirror must be checked.
Make sure that the speed ring is set to shutter speed mode.
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. At the same time (not before) the PRS should change from "open"
to "closed" on the screen. A slight delay is acceptable. This corresponds to 1.5
divisions on the scale.
Adjust, if necessary, by altering the position of the self timer board (Pos No. 42,
page 9:2). Untighten the two screws (Pos. No. 40, page 9:2) and carefully change the
position of the board in the direction required. Tighten the screws and recheck.
5:2 SPEED RING: Make sure all speed ring settings are indicated correctly.
5:3 TIMER INDICATOR: Check that the self timer LED is lighthing up.
