1) SW1(L/L):
If this switch is set to OFF, the camera will
operate in the internal synchronization mode, and
if the switch is set to ON, the camera will operate
in the line lock mode.
If you are monitoring in the automatic switching
mode with multiple cameras connected to a
sequential switcher, and the cameras are set to
INT (internal synchronization) mode, then picture
rolling or flickering will occur during switching
from one camera to another.
Such picture rolling on the monitor can be
remedied by setting this switch to ON and then
adjusting the vertical sync phase with the
V-Phase Control.
When using DC 12V power, set the L/L switch to
OFF.
If the L/L switch is set to ON, the camera will not
operate normally.
2) SW2(BLC):
This switch turns on or off the back light
compensation (BLC) function. When there is a
spotlight or strong light from behind the subject,
the subject may appear dark on the monitor. In
such backlighting conditions, set this switch to
ON for clear viewing.
3) SW2 (ELC):
Use this switch with the Manual Iris Lens. While
this switch is ON, the speed of the electronic
shutter varies with the brightness of the subject
from 1/60 to 1/100,000 sec for automatically
controlling the brightness of the screen.
However, with the Auto Iris Lens (DC or Video
Control), be sure to switch OFF.
4) SW4(AGC):
This switch turns on or off the automatic gain
control (AGC) function, which is a function that
automatically increases the camera's sensitivity
when ambient light drops below a preset level.
Set this switch to ON to automatically adjust the
"gain".
⑤ DC Iris Level Control
When the ALC Lens Selection Switch is set to
DC, adjust this Iris Level Control using an
adjustment rod such as a screwdriver.
➅ Video Output Terminal
This is a terminal to be connected to the Input
Terminal of the monitor. Through this terminal,
the video signals are output.
