may be a vertical roll of the images when
switched. In such a case, set as described
below.

Set the SYNC switch to the L-L position.
2
Switch the display on the monitor from
camera 1 to camera 2.
Adjust the LINE PHASE volume on
camera 2 until the vertical roll of the
image stops.
If more than two cameras are used,
please repeat this procedure for all the
cameras.
CAUTION:
If the vertical roll cannot be corrected by
setting the LINE PHASE volume on camera
2, try setting the LINE PHASE volume on
camera 1. If it still cannot be corrected,
please check that the polarity of the power
cords of all connected devices is correct.
