3.0 INSTALLATION
Proceed with the installation of the fixed mount after you have installed the back
box.
If a camera/lens package has not been installed on your fixed mount, you can in-
stall the camera/lens either before you install the fixed mount in the back box or
after you install the fixed mount. If you want to install the camera/lens first, proceed
to Sections 3.2, LENS WIRING, and 3.3, CAMERA/LENS INSTALLATION, then
return to Section 3.1, FIXED MOUNT INSTALLATION.

2. Remove the hairpin clips from the two latches inside the back box (refer to
Figure 1) and open the latches.

The 25-pin connector on the fixed mount will go into its mating connector

the back box.
The two guide pins on the back box will go into the bushings on the upper
bracket of the fixed mount.
b. Push the fixed mount into place and close the latches.
c. Reinstall the hairpin clips in the latches to prevent the latches from open-
ing.
Proceed to Sections 3.2, LENS WIRING, and 3.3, CAMERA/LENS IN-
