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 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.
• Refer to "7. LINE-LOCK PHASE" for adjustment.
