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 cover using the supplied
2.Adjust the vertical phase, iris level, focus, or switch settings (refer to procedures below).
3. Replace the cover.
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 transformer, this should solve the problem.

transformers, 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. | Figure 11. Vertical Phase Adjustment |
AUTO IRIS LEVEL ADJUSTMENT
