LINE-LOCK CONTROL (TSE270X/TSE272X)
Matching the vertical synchronization with the power frequency is called the line-lock.
When two or more cameras are switched by the video switcher to 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.
Caution:
1.The camera is synchronized to the power frequency of 60Hz ±0.5Hz covering a normal fluctuation of the power
frequency.The camera may not compensate for large fluctuation caused by power generated by an engine
generator, etc.
2.It takes about 10 seconds or more to obtain a stable synchronization after the power is turned on. This is
necessary to stabilize the camera against the power noise.
