E-6

 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 0.6 lx

(F1.2, 50%, AGC 20dB) and 0.019 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.

 Electronic zoom

The 10x electronic zoom allows

monitoring in far greater detail.

Features

 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 where

it is dropped because of bad installation

due to failure to observe the installation

instructions correctly. Please be careful

when installing the camera.

 The motion detector is not a feature

which prevents theft, fire, etc. Even if

an accident should occur resulting in

damage, we do not accept any liability.

E-7

● 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 outdoors, be sure

to use a housing or 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 the AGC is activated, if a transceiver

which causes strong electromagnetic wave

is at close distance, the picture might suffer

from beat.

So please use the camera more than three

meters 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

operational principles of the auto-tracking

white balance circuit. However, this is not

a malfunction.

Operating Precautions

● 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.

● 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.

● The unit is to be powered by a DC 12 V or

an AC 24 V power supply. (TK-C1480BE)

The AC 24 V power supply should conform

to the following: Isolated power supply only

TK-C1481BEG Connect the power cable

to the commercial power supply of 230V.

● Caution for operating the video iris lens.

If the video iris lens is set to an extremely

low level, a malfunction – such as the

hunting phenomenon where the iris opens

and closes involuntary – 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.

● 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

on the vertical lines of the subject.

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.
