7.AGC ON/OFF Switch

This switch is provided for the AGC circuit. The AGC circuit incorporated into the camera boosts the sensitivity automatically when the scene illumination is insufficient.

8.INT/LL Switch (LL is ON; INT is OFF)

This camera can operate independently, using its internal crystal-controlled sync generator, or it may be synchronized using line-locking.

To select one or the other of these sync modes, set the DIP switch on the rear panel to either INT or LL. Switch 4 is set to ON for LL and OFF for INT.

If line-lock is selected, all the cameras in the system must be adjusted to begin the video field scan at the same time. This is described in procedure ⑩.

9.FL ON Switch (Flickerless ON/OFF)

This function is only used in JAPAN. In order to use FL mode, set EE/AI switch to AI first and then FL ON/OFF switch to ON.

When the DIP switch on the rear panel is set to ON, the shutter speed is fixed at a rate of 1/100(120)(sec).

10.V-Phase Adjustment Potentiometer

This potentiometer is set full counter clockwise at the factory. If two or more cameras are connected to a switcher and the picture on the monitor rolls while switching from camera A to B, adjusting the vertical phase (V-phase) of the cameras will probably eliminate the rolling. If this adjustment is necessary, it should only be performed by a qualified technician. Before making any adjustment, confirm that cameras A and B are connected to the power supply with the same polarity.

To make an adjustment, follow the steps below.
