Pelco Manual C2410M-H (10/05) [ 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.

3 Install Dome and Trim Ring
Place the trim ring and dome over the back box. If the
dome has a liner, position the viewing window over the
lens of the camera. Tighten the tamper-resistant screws
with the supplied 1/8-inch hollow screwdriver bit. Note
that the screws are installed at an angle.
