¥ When connecting to DC power supply, the Line Lock function is not activated.

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.
