CAUTION:
The phase adjustment must be made by a qualified service person
or installer.
Line-lock is automatic when the camera is connected to a 24 VAC power
supply. If two cameras are connected to different AC supplies with
different phases, the cameras can be synchronized. Synchronize the
cameras 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.
Adjust the line-lock phase by pressing the line-lock phase adjust buttons
on the PC assembly (Figure 13).
