Pelco Manual C2407M-G (5/03) [ 7 ]
ADJUSTMENTS (COLOR CAMERA ONLY)
If you have a color camera, it is set up at the factory and normally requires no adjustments. Sometimes,
however, adjustments may be necessary.
1. Remove the dome and trim ring using the supplied 1/8-inch hollow screwdriver bit.
2. Adjust the vertical phase, iris level, focus, or switch settings (refer to procedures below).
3. Replace the dome and trim ring.
Vertical Phase (24 VAC Operation Only)
Adjustment is required if there is vertical roll when switching between two cameras.
1. Reverse the 24 VAC connections on one camera. If both cameras are connected to the same trans-
former, this should solve the problem.
2. If reversing the connections does not solve the problem, or if cameras are connected to different trans-
formers, turn the adjustment screw on one camera (while switching as rapidly as possible between the
two camera views) until the switching is clean and there is no vertical roll. If more than two cameras are
out of synchronization with each other, choose one camera and synchronize all others to it.
4 Install Dome and Trim Ring
1. Align the screw holes in the trim ring with
those in the camclosure base.
2. Domes with Liners (only) –
Position the viewing window over the
lens of the camera.
a. Loosen the three Phillip screws
located in the dome.
b. Insert the blade of a standard screwdriver
in one of the adjustment grooves. Move dome
into position.
c. Tighten the three Phillip screws to lock liner in place.
3. Tighten the tamper-resistant screws with the supplied 1/8-inch hollow screwdriver bit.
