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.

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. Pole 4 is set to ON for LL and OFF for INT.
If line-locking 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 (

FLON Switch (FLICKERLESS ON/OFF)
This function 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).

V-Phase Adjustment Potentiometer
This potentiometer is set full counterclockwise 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.
