Matching the vertical synchronization with the power frequency is called the 
This function is activated when the LINE LOCK switch is set to ON.
When two or more cameras are switched by the video switcher for viewing by a monitor TV, the vertical sync. phase can be locked with the power frequency, and a stable vertical sync. is obtained without being disturbed at the time of switching.
) POWER CORD (twisted pair line)
The camera is synchronized to the power frequency of 60 
1 Hz covering a normal fluctuation of the power frequency. However, the camera may not cover a large fluctuation caused from the power generated by an engine generator, etc.
It takes about 10 seconds or more until a stable synchronization is obtained after the power is turned on. This is normal, because several seconds are required to stabilize the camera against power noise.
