10.	designed to operate from battery power, refer to the operating instructions.
	This appliance system is equipped with a 3-wire grounding type plug (a plug having a third (grounding) pin). This
	plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into
	the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding
	plug.
11.	For added protection for this product during a lightning storm, or when it is left unattended and unused for long
	periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent
	damage to the product due to lightning and power-line surges.
12.	Do not allow anything to rest on the power cord. Do not locate this appliance where the cord will be abused by
	persons walking on it.

COLOR VIDEO CAMERA			Instructions
Thank you for purchasing the JVC color video camera.
To obtain the best results from your new camera, read these instructions carefully before use;
retain the manual for future reference.
WARNING:
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOIS-
TURE.
Information for USA
This device complies with Part 15 of the FCC Rules.
Changes or modifications not approved by JVC could void the user’s authority to operate the equipment.
INFORMATION (FOR CANADA) RENSEIGNEMENT (POUR LE CANADA)
This Class [B] digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe [B] est conforme à la norme NMB-003 du Canada.
PRECAUTIONS
•	This unit incorporates the AGC (Auto Gain Control) function, which increases the sensitivity
•	automatically in dark places. It is not a malfunction when the image looks grainy in dark conditions.
	Before mounting the camera, first mount the lens to be used with the camera, and then operate
•	it in order to check the back focus.
	If a high-intensity object (such as a lamp) is in 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.
	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.
	This unit assumes that the light source being used is either natural lighting (sunlight) or
	incandescent lamps (color temperature 2300K-10000K).		Under special light sources, such as
•	sodium lamps, colors may appear different compared to what is visible to the eye.
	Noise may appear in the picture and/or the colors may be incorrect if the camera is used near a
	radio or television transmitting antenna, in places where strong electromagnetic waves are
	generated by transformers, motors, etc., or near devices emitting radio waves, such as
•	transceivers or cellular phones.
	This unit accepts only a DC iris lens.
•	To save energy, be sure to turn off the system when not in use.			∆A
MOUNTING A LENS
1.	Before mounting a lens, check whether it is a C-mount or CS-mount lens.
	If a C-Mount lens is used, loosen the back-focus locking screw (M 2.6) using a Phillips			∆B
	head screwdriver, turn the back-focus adjusting ring with your fingers or the screw-
2.	driver and change the mounting method.
	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
	or correct mounting may be impossible; never use such lenses. Do not attach a C-
	mount lens when using the 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	∆C
	The F mark indicates a focal point.

3.Mount the DC IRIS lens on the camera by turning the lens clockwise. Adjust its position.

4.If the lens has an auto-iris mechanism, connect the lens cable after checking the pin assignment.

CONNECTION
1.	When the camera is powered, the POWER LED lights up.
	CAMERA type			Power
	TK-C750U	AC 24V ` (class 2 only)
	TK-C750E	AC 24V ` (isolated power only)
2.	Connect to a video monitor, etc. (75 Ω)							∆D
3.	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 a screw shorter in length than 7mm from the camera-mounting
	face.
	Furthermore, make use of the rotation prevention holes (e) to prevent the camera
	from falling and be sure to mount the camera securely.
	Special precautions must be taken when mounting the camera on a wall or a ceiling.
	JVC is not liable for any damage caused by incorrect installation.
4. Installation of camera								∆E
	• With the mounting plate on the underside
	This camera is originally designed to be mounted from underneath, as shown q.
	The hole is standard photographic pan-head screw size (1/4-20 UNC, as is found
	in a typical camera fixing point or pan & tilt head.
	• With the mounting plate relocated to the topside
	Remove the CAMERA MOUNTING BRACKET (f) from the underside of the camera
	by removing the 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.
	These instructions assume the camera will only be mounted indoors.
Fall Prevention								∆F
•	Exercise maximum caution when installing the unit to a wall or ceiling. If in any doubt
	ask a professional to do the job, because if the unit were subsequently to fall, it
•	could result in personal injuries or accidents.
	When installing the unit on a fixer, turn table, etc., be sure to install it firmly and to
•	use one of the rotation-preventing holes (e) provided.
	As a failsafe against falling, attach the unit by chain, wire cable or other safety restraint
	to an appropriate anchor point. Attach the fall prevention wire using the black screw
	on the upper surface of the camera as shown in figure F. When changing the side at
	which CAMERA MOUNTING BRACKET is installed, be sure to change the attachment
•	side of the fall prevention wire also to the appropriate side.
	Specified screw (M2.6 × 4 mm)
	Never use any screw longer than the specified length as the inside can be damaged.
