1. Handle the camera with care.
Be careful when handling the camera, do not drop it or subject
it to strong shock or vibration to prevent any damages to it. Do
not disassemble it or place it on an unstable base.
2. Do not install the camera near electric or magnetic fields.
Installed the camera away from TV, radio transmitter, magnet,
electric motor, transformer, audio speakers because the
magnetic fields generate from above devices will distort the
video image.
3. Do not install the camera in the high temperature environment.
Installed the camera away from stoves, or other heat
generating devices as the high temperature could cause
deformation, discoloration or other damages of the camera.
Install the camera at where the temperature range will stay
between 0℃to 50℃ (32℉to 122℉).
4. Never face the camera toward the sun.
Never aim the camera at the sun or other extremely bright objects
whether it is in use or not.
5. Cleaning
Do not touch the surface of CCD sensor by hand directly. Use
a soft cloth to remove the dirt from the camera body. Use lens
tissue or a cotton tipped applicator and ethanol to clean the
CCD sensor and the camera lens. When the camera is not in
use, put the cover cap on the lens mount.

1. Focal Length Adjustment Ring
Use this ring to adjust the appropriate focal length according to the type of
lens. Rotate the ring clockwise for the CS-mount lens, rotate it
counterclockwise for the C-mount lens. The factory setting is C-mount.
2. Lens Mount
To mount an appropriate C-mount or CS-mount lens.
3. Locking Screw
Use the locking screw to fix the focal length.
4. Lens Connector (4 pin socket)
To connect to the lens plug of the auto IRIS lens.
5. Control Switches
There are 6 control switches located on the sideboard, which are for the
setting of the special features. The switches in orders are for Flickerless,
Back Light Compensation, Electronic Shutter, Automatic Gain Control,
Line-Lock and Auto Iris Lens type.
FL(Flickerless) On/Normal
When picture flicker fiercely, turn FL on, then the camera will stabilize the
speed of electronic shutter at 1/100(EIA) or 1/120(CCIR) automatically, and
reduce the flicker immediately. The default setting is Normal.
BLC (Back Light Compensation) On/Normal
When BLC is turned on, the AGC, ES and IRIS operating point is
determined by averaging over the center area instead of entire field-of-view,
so that a dimly-lit foreground object at center area can be clearly
distinguished from brightly-lit backgrounds.
BLC should not be used unless it is needed to compensate for back-lit. The
default setting is Normal.
5

ES (Electronic Shutter) Off/On
ES ON: The camera continuously adjusts the shutter speed from 1/60 (EIA),
1/50(CCIR) second to 1/100,000 second according to the
luminance conditions of the scene.
ES OFF: The shutter speed is fixed at 1/60 (EIA), 1/50 (CCIR) second.
Set ES OFF, when auto iris lens is used or flicker is observed under a very
bright fluorescent lamp. Otherwise, turn ES on for optimum performance.
The default setting is ON.
AGC (Automatic Gain Control) Off/On
AGC ON: The sensitivity increases automatically when light is low.
AGC OFF: A-low-noise picture is obtained under a low light condition.
The default setting is ON.
LL (Line-Lock) Off/On
To select the sync mode between Internal Sync.(LL off) and Line-Lock
(LL on).
Set the line-lock off, the camera will synchronize to the internal time base.
Set the line-lock on, the camera’s vertical synchronization can be driven by
the AC signal in the power lines.
Note: Line-Lock sync mode operation is possible only when used with an
AC power source; it’s not possible with a DC power source.
