Unlocking
If engaged, unlock the exposure device's
plunger lock with the key.
Rotate the selector ring to the OPERATE position.
Ensure there is no tension/force in either direction
on the control cable.
Push the lock slide GREEN MARKING laterally
from left to right (as seen behind the projector)
until the lock slide RED MARKING fully appears
on the right side of the selector ring and you
feel or hear the sleeve snap into the slide.
When the GREEN MARKING is visible,
the source assembly is locked into the secured
position within the exposure device.
When the RED MARKING is visible, the source
assembly is free to be projected from, and retracted
to, the projector.
Ensure all personnel leave the immediate area.
Go to the remote control crank.
If an odometer is fitted, adjust the reset knob
to read zero.
The source assembly can now be projected.
