Service Manual

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 rear section of the contact flex
containing the PRS.
Untighten the two screws (Pos. No. 12, page 9:1) and carefully change the
position of the flex in the direction required. Tighten the screws and recheck.
7:2 PANEL: Check the control panel functions.
7:3 DISPLAY: Check the display indications.
Note! The sync cable must be connected to the TTL connector.
7:4 CURRENT: Check the consumption (max. 10 mA at 5.6 volt) and the drain (max.
20 uA at 5.6 volt).
7:5 LENS: Check the communication between a lens and the camera body. (F-stops)
7:6 MAGAZINE: Check the communication between a magazine and the camera body.
7:7 SHUTTER: Start by adjusting the travel times. Use 1/1000 sec. and adjust the spring
housing until both curtains have a speed between 9.6 - 9.9 ms. (0 ± 0.11 ms).
At this point, also make a final adjustment of the braking mechanism if necessary.
The brake is checked as follows: Release the camera. Rotate the 2nd shutter gear
(Pos No. 18, page 16:1) and count the number of times the catch (Pos No. 4, page
17) and the brake plate (Pos No. 3, page 17) engage. (Min. 4 times). For an
adjustment use the nut driver 903755 or 903474. (See page 3:4).
Check/adjust the speed 1/1000 sec. Use the "shutter speed" potentiometer for
an adjustment. (See page 3:4). Max. deviation ± 0.3 EV.
7:8 LIGHT METER: Check/adjust the light meter. Use the "light meter" potentiometer
for an adjustment. (See page 3:4). Max deviation ± 0.3 EV. Do not use any
other light output except EV 15, since the camera is not mounted in the shell.
7:9 FLASH SYNC: Check/adjust the flash sync. The delay is adjusted to 0 - 0.20 ms by
altering the position of the first sync contact. (See page 3:4).
7:10 FLASH METERING: Check/adjust the flash meter. Use the "flash meter"
potentiometer for an adjustment. (See page 3:4). Max. deviation ± 0.3 EV. Use ISO
setting 100 and light output EV 15.
8. Remove the control panel. Make sure the four centering screws (Pos. No. 7 and 10,
page 10:1) are screwed in and put the camera body in to the shell.
Do not forget the pre-release button.
