INTRODUCTION

Features

A new DSP (Digital Signal Processor) features a Extended Dynamic Range (ExDR) and enables to shoot both bright and dark locations.

The use of a new CCD with a SENSE UP (X32) function realized the minimum luminous flux density for subject of 0.8 lx (F1.2, 50%, AGC 20dB) and 0.025 lx (at slow shutter).

A motion detector function detects the motion inside an image and emits alarm signals.

The equipped Y/C terminals and RS- 422A/RS-485 terminals allow intended compatibility with diversified systems.

Before starting an important recording, be sure to perform a test recording in order to confirm that a normal recording is possible.

We do not accept liability for the loss of a recording in the case of it becoming impossible to record due to a problem in the video camera, VCR or video tape.

We do not accept liability for any damage to the camera in cases when it is dropped because of incomplete installation due to not observing the installation instructions correctly. Please be careful when installing the camera.

The motion detector is not a feature to prevent theft, fire, etc. Even if an accident should occur resulting in damage, we do not accept any liability.

Operating Precautions

●	To save energy, when it is not being used
	turn the system’s power off.
●	This camera has been designed for indoor
	use. When you use it outdoor, be sure to
	use a housing and the like.
●	Do not install or use the camera in the
	following places.
	• In a place exposed to rain or moisture.
	• In a place with vapor or oil soot, for
	example in a kitchen.
	• When the ambient temperature rises
	above or falls below the acceptable
	range (from –10°C to 50°C).
	• Near a source of radiation, X-rays,
	strong radio waves or magnetism.
	• In a place subject to vibration.
	• In a place with excessive dirt.
●	If this camera and the cables connected
	to this camera are used where there are
	strong electromagnetic waves or where
	there is magnetism present, for example
	near a radio or TV transmitter, power
	transformer or an electric motor, the picture
	may produce noise and the colours may
	be affected.
●	This camera incorporates an AGC circuit.
	As a result, when it is used under low light
	conditions, the camera sensitivity is
	automatically boosted and the picture may
	look uneven. However, this is not a
	malfunction.
●	While AGC activated, if use kind of transceiver
	which cause strong electromagnetic wave at
	close distance, picture might have influence
	for beat and etc.
	So please kindly use camera more than three
	meters apart from such transceivers.
●	When this camera is used in the ATW
	mode, the recorded colours may be slightly
	different from the actual colours due to the

●Observe the following when carrying out camera maintenance.

• Turn the power OFF before proceeding

to carry out maintenance. If it is contaminated seriously, clean the contaminated part with a cloth (or a tissue) which has been soaked in a solution of water and a neutral detergent.

●	TK-C1480U and TK-C1480E
	The unit is to be powered by a DC 12 V or
	an AC 24 V power supply.
	The AC 24 V power supply should conform
	to the following:
	TK-C1480U Class 2 only
	TK-C1480E Isolated power supply only
	TK-C1481EG Connect the power cable
	to the commercial power supply of 230V.
●	Caution for operating the video iris lens
	In case the video iris lens is set to an
	extremely low level, malfunction – such as
	the hunting phenomenon in which the iris
	opens or closes unintentionally – can
	occur.
	In such a case, first set the “LEVEL”
	potentiometer on the lens to the H position
	(iris open), and then adjust it to an optimum
	level.
●	A CCD is made by high technology,
	boasting an exceptionally high level of
	precision with an effective pixel of more
	than 99.99%. Although there is a less than
	0.01% pixel defect (whitish flaw, blackish
	flaw), this does not mean that the CCD is
	out of order.
●	The cable stopper on the terminal block
	can come off sometimes. Therefore, be
	sure to take enough time and fix the cable
	securely.
●	When a highly bright subject is shot,
	sometimes undulations can be observed

	white balance circuit. However, this is not
	a malfunction.
●	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. This is a characteristic of
	the CCD, and is not a defect.

	However, this phenomenon is peculiar to
	the unit and is not a sign of malfunction.
●	The beat may sometimes appear on the
	screen if gain is raised when the line lock
	is in use, but the phenomenon takes place
	due to the fluctuation of power frequency
	and is not a malfunction.
