This section describes procedures for repairing and replacing parts.
It includes opening the optical unit, and replacing the lamp, filter,
film disc cutout assembly, optical unit, and L-823 cordset. It also
describes how to close the optical unit.
To open the optical unit, perform the following procedure:
1. Turn the light unit upside-down.
2. See Figure 6-1. Remove the pressure release screw (E11).
NOTE: Removing the pressure release screw equalizes the
pressure inside and outside the fixture, making it easier to break
the seal and remove the inner cover.
