CAUTION:
The phase adjustment must be made by a qualified service person
or installer.
The vertical phase of the camera video signal can be synchronized to the
phase of the AC power line by using a dual-trace oscilloscope to observe
the video output signal (V-rate) of the camera and by adjusting the line-
lock phase control buttons to line up the phases of both signals, or by
using a KTS-56 V-Phase Adjustment Tool. In line-lock mode, this
synchronization is automatic.
