The miniature lamp, which is visible just over the camera hand grip is paired with
another lamp, located inside the camera. The inside lamp flashes whole frames
of film, during camera run-up time. The result is that the beginning of each take,
three or four frames of film are flashed. The start mark on the tape corresponds
with the point just past the last flashed frame on the film. Light from the interior
marking lamp in visible in the viewfinder, during run-up time. Note that the lamps
are activated only when a properly wired cable is plugged into the 5-pin Tuchel
outlet.
To remove the start marking lamps for
replacement, turn the plastic housing on
its metal base counterclockwise. The pair
of lamps are secured to the ends of the
black rod (P1) which may be lifted out.
These lamps are resistance matched
pairs, and must always be replaced with a
new, matched pair.

8 Volt DC Output
At the same time, during which the start mark lamps are energized, the camera
will supply 8 volts DC through pin 3 on the Tuchel outlet. (See schematic).
This voltage energizes a 1000 cycle oscillator built into the tape recorder. The
1000 cycle signal is recorded on the tape and serves as a start-mark in the
sound track. The oscillator is cut off simultaneously with the marking lamps in
the camera. Therefore, the point where the 100 cycle signal ends on the tape,
corresponds with the point where the flashed frames end on the film and
constitute the sync point.

Edge Marking System
The edge-marking lamp is mounted in the
base of the camera under the coin slotted
contact screw. The mating indicator lamp
for edge marking is located on top of the
small generator casting on the right side
of the camera. These lamps are also a
matched pair and should be replaced with
matched pairs.

At the start of a take, the edge-marking lamps work simultaneously with the full
frame marking lamps. However, these lamps mark the film at the edge only, and
the edge marking is displace on the film by about 3 ½ frames from the aperture in
direction of travel. The edge-marking lamp can be energized manually during a
take for event marks of various kinds.
