5. Synchronisation failure.
Adjusting the flash synchronisation.
EXA
Dismantle the camera, as under Camera Disassembly A.1 - A.4.
a) Set the exposure time lever to the 1/25 sec position and cock the shutter.
b) Holding the leading edge of the shutter flap with a finger, fire the shutter and let the leading
edge of the shutter flap run slowly. The X-contact must fire near the position shown in Fig.
5, and the F-contact near the position shown in Fig. 6. If they do not do so, the contact
spring must be bent at the flash contact accordingly.
c) Reassemble the camera, see Assembly of Camera B.1 - B.5.
Adjusting the flash synchronisation.
EXA I/63
Note:
The setting of both flash contacts (X and F) depends on the linkage between the time setting
disc 350.21 U 3 and the contact disc 350.22-13 on insulating-part I 350.22 U 4. Because of
this, setting the shutter times causes at the same time a changeover of the contacts.
The X-synchronisation takes place at shutter speeds of 1/60 sec and B.
The F-synchronisation will operate at shutter speeds of 1/175 sec, 1/125 sec and 1/30 sec.
