Safety Precautions
Introduction
E-5
English
● 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.
• Clean the dome cover lens using a lens
wiper cloth (or a tissue).
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.
● Do not install the unit in an environment
where there is cold air or near the air outlet
of an air conditioner. The dome cover will
cloud as a result.
● If the D/N switch is turned on, the mode
changes automatically to black and white
in dark places. As the sensitivity increases,
the image may look grainy and white spots
may appear. When changing modes, bright
portions of image may be emphasized but
this is not a failure of the camera.
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. It cannot be used outdoors.
● Do not install or use the camera in the fol-
lowing places.
• In a place exposed to rain or moisture.
• In a place with vapor or oil soot, for
example in a kitchen.
• In a temperature outside the operating
temperature range (–10°C to 50°C).
• Near a source of radiation, X-rays, strong
radio waves or magnetism.
• In a place where corrosive gasses are
generated.
• 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 trans-
former or an electric motor, the picture may
produce noise and the colors may be af-
fected.
● This camera incorporates an AGC circuit.
As a result, when it is used under low light
conditions, the camera sensitivity is auto-
matically boosted and the picture may look
uneven. This is not a malfunction however.
● When this camera is used in the ATW
mode, the recorded colors may be slightly
different from the actual colors due to the
operational principles of the auto-tracking
white balance circuit. This is however not
a malfunction.
