When using more than one camera power supply, a brief vertical roll may occur on the monitor

It may be necessary to have two people in communication when synchronizing the cameras–one
person at the camera and another person at the monitor to observe the vertical roll and the effect
of any adjustments made at the camera.
person at the camera and another person at the monitor to observe the vertical roll and the effect
of any adjustments made at the camera.
To synchronize the cameras do the following:
1. Choose a camera to which all of the other cameras will be synchronized.
2. Select a second camera that is out of synchronization with the first camera.
3. Adjust the camera phase by pressing the LL switches up or down.
4. Switch the cameras back and forth, observing the roll between the cameras when they are
switched.
5. Press the LL switches up or down and observe the roll each time an adjustment is made.
6. Repeat this process as many times as necessary for each camera in the system.
