PRECAUTIONS

•If an AGC switch is turned on, the sensitivity increases automatically in dark places. It is not a failure when the image looks grainy.

•If a zoom lens is used, check the back focus before mounting the camera. This also applies to lens ALC and LEVEL. (See the instructions on lenses for details.)

•If a high-intensity object (such as a lamp) is shot, the image on the screen may have vertical lines (smear) or blur (blooming) at its periphery (especially in AES mode). This is a characteristic of the CCD, and is not a defect.

•If an EE lens is used, set the automatic electronic shutter switch (AES) to OFF. If set to ON, flickering may occur. If a manual iris lens is used, set the AES to ON.

•When used in hot places, vertical lines may appear on the screen of this camera. This is a characteristic of the CCD and not a failure of the camera.

•The automatic tracking system may not function properly when shooting with non-standard lighting or lighting with a color temperature which exceeds the capability of the camera. In such a case, set to the “MANU” position.

•If the camera subject is a single solid color (other than white), the auto white circuit will normally attempt to change this color to white. In the case of this camera, if it cannot make a correct prediction, the previous white balance setting will be maintained until the subject colors become more varied.

•Where there are strong electromagnetic waves or magnetism, for example near a radio or TV transmitter, transformer, motor, etc., the picture may contain noise and the colors may be incorrect.

•Beware of the instruction of noise when installing the twisted pair cable that is used as a connection.

•To save energy, be sure to turn off the system when not in use.

MOUNTING A LENS
1. Before mounting a lens, check whether it is a C-mount or CS-mount lens.					∆A
If a C-Mount lens is used, loosen the back-focus locking screw (M 2.6) using a Phillips
head screwdriver, turn the back-focus adjusting ring with your fingers or the screw-
driver and change the mounting method.
2. Dimension (b) of the lens shown in the illustration must be as shown in the table
below. If (b) exceeds the value in the table, it may damage the inside of the camera					∆B
or correct mounting may be impossible; never use such lenses. Do not attach the C-
mount lens when using a CS-mount.
Lens	Flange back (c)		Dimension (b)
C mount lens	17.526mm		10mm or less
CS mount lens	12.5mm		5.5mm or less
The F mark indicates a focal point.
3. Mount the lens on the camera by turning the lens clockwise. Adjust its position.					∆C
4. When using an auto-iris lens with an EE amplifier, turn the switch to the “VIDEO”
side. When no EE amplifier is equipped, turn the switch to the “DC” side.
5. If the lens has an auto-iris mechanism, connect the lens cable after checking the pin
arrangement.
If the lens cable has a different type of plug, use the 4PIN PLUG supplied.					1	3

•Never connect the DC 12V and AC 24V power inputs simultaneously.

•Be sure to observe the correct +, – polarity when connecting a DC 12V power input.

2.Connect the VIDEO OUT +/- terminals, which are on the rear panel, to the +/- terminals on the receiver using twisted pair cable.

3. MONITOR Terminal
The MONITOR Terminal is for connecting to a video monitor. The MONITOR Termi-
nal is used for adjustment of screen framing.
*The VIDEO OUT and MONITOR Terminal cannot be used simultaneously.

4.When mounting the camera on a fixer, pan/tilt, etc., use the camera mounting screw hole (d) located on the camera-mounting bracket.

CAUTION: Use the screw with a length shorter than 7mm from a camera-mount-

ing face.∆D Furthermore, make use of the rotation prevention hole (e) to prevent the camera

from falling and securely mount the camera.

Special precautions must be taken for mounting the camera on a wall or a ceiling.

We are not liable for any damage caused by improper installation.∆E

5.Installation of camera

•Mounting from the bottom

This camera is originally designed to be mounted from the bottom, as shown q. The hole is standard photographic pan-head screw size (1/4-20 UNC). Example the Fixing unit or Pan/Tilt unit.

•Mounting from the top

Remove the CAMERA MOUNTING BRACKET (f) from the bottom of the camera by removing two fixing screws as shown w. Attach the CAMERA MOUNTING BRACKET (f) to the top, then mount the camera on the Fixing Unit as shown e. Make sure that two original screws are used when mounting the CAMERA MOUNTING BRACKET (f). Be sure to use a 6 mm long locking screw for the camera-mounting bracket.

(This camera is used indoor and under similar conditions.)

Fall Prevention

•	Exercise maximum caution when installing the unit to the wall or ceiling. You should
	not engage in the installation work yourself. Ask a professional to do the job, since	∆F
•	the fall of the unit can result in injuries and accidents.
	When installing the unit on a fixer, turn table, etc., make sure to install it firmly using
•	a rotation-preventing hole provided to prevent fall.
	To prevent fall, connect the unit to a section with sufficient strength (ceiling slab or channel)
	using a fall prevention wire such as a wire chain and the like. Use the screw hole on the back of
	the unit for installation.
	Pay utmost attention to the length of the wire, too.
