Repair manual

The rear blade which cover the lenses and terminates the exposure,
will be shown by the line “E” to “F”. If the blade is uniformly
slow, the picture will be:
D E
A F
If this blade starts slowly and then accelerates to normal speed,
the picture will be:
D E
A F
With this information all being shown by the oscilloscope picture,
it should be apparent that the operator must observe carefully the
oscilloscope trace on the 1/100 and 1/50 setting before attaching
the flash connection. If any abnormal condition exists, correct it
before continuing with the shutter and switch testing.
R - With the flash connection on the camera, Check the shutter
timing at 1/50 (should read from .018 to .044); then, at 1/10
(should read from .09 to .11) Check all shutter speeds after
the flash is adjusted.
24.200 Set Flash For Strobe
A strobe unit, which has an adjustable delay on it can be used
with the “Personal Camera” without any change to the camera simply
by adjusting the delay to 7 milliseconds. In order to use a
strobe unit that has no delay, a change in the flash switch
adjustment may be necessary. Remove bottom and back from camera.
It will be necessary to bend the switch drive blade so that it
looks thus:
Switch set for strobe Normal Switch
(Note difference in drive blade)
This adjustment is made to bring pint “B” (See diagram Section
24.100 – J) as close to “D” as possible. Follow instruction in
“Shutter timing” (Section 24.100) except for above noted change.
Adjustment can be double checked by connecting strobe unit to
camera and releasing shutter while looking through camera.
