• Matching the vertical synchronization with the power frequency is called the Line Lock.
• To activate the line lock, set the LL switch to ON.

• When two or more cameras are switched by the video switcher for viewing with a display monitor

the vertical synchronization phase can be locked to the power frequency for a stable vertical
synchronization.

Note:
• 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 a generator, etc.

• It takes approximately 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.

• Refer to section 7. "LINE LOCK PHASE" for adjustment instructions.
