CAMERA CONTROLS
AGC switch
In case of necessity, set the AGC switch to OFF position.
BLC (Black Light Control) switch
With the AGC switch at ON position, BLC are available. In case the back lighting is too bright
to shoot the main object clearly, set this switch to ON position.
INT/LL switch
• INT. (internal) control
switch
When the internal
synchronization is used,
set the switch to the INT
side.
• L.L. (Line-lock) control
switch
Matching the vertical
synchronization with
the power frequency is
called the line-lock.
When the AC24V
power supply is used,
set the switch to the LL side.
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
