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.
