E-6
Ⅲ A new DSP (Digital Signal Processor)
features a Extended Dynamic Range
(ExDR) and enables to shoot both bright
and dark locations.
Ⅲ 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).
Ⅲ A motion detector function detects the
motion inside an image and emits alarm
signals.
Ⅲ The equipped Y/C terminals and RS-
422A/RS-485 terminals allow intended
compatibility with diversified systems.
Features
Ⅲ Before starting an important recording,
be sure to perform a test recording in
order to confirm that a normal
recording is possible.
Ⅲ 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.
Ⅲ 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.
Ⅲ 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.

● 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
operational principles of the auto-tracking
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.
Operating Precautions
● 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
on the ver tical 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.
