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