• When using a zoom lens, it is recommended to run the camera
with your zoom lens attached and check the backfocus before
camera installation. The same applies to lens attached and check
the backfocus before camera installation. The same applies to lens
level adjustment. (See the lens instruction manual for details.)
• Be sure to attach the provided ferrite core to the lens cable or
power cable to be connected with this camera to minimize unnec-
essary radiation.
• Avoid istalling in places where there is radiation.This could damege
CCD and other components and cause a malfunction.
• Avoid installing in places where there are strong electro-magnetic
waves or magnetism. the picture could be distorted.
• Avoid instanning in places where the camera would be subject to
strong vibrations. This could damage components and degrade
the picture.
• Avoid installing the unit in following locations.
• Places exposed to rain or moisture
• Places with an ambient temperature outside the range of –10
to 50°C (operation) or from 0 to 40°C (recommended).
• Places subject to excessive dust or to oil or gas.
• When this unit is used with AGC ON, an image recorded in a dark
place may look noisy due to the automatic boost in sensitivity.
This is not a malfunction.
• When this unit is used with the AUTO white balance control, the
recorded colours may differ slightly from the actual colours due to
the operation of the automatic-tracking white balance control cir-
cuit. This is not a malfunction.
• When a bright object (such as a lamp) is shot, a white, comet-tail
phenomenon may be observed above and below the bright object
on the screen. This is a phenomenon (called smear) inherent in
CCD image pickup devices and is not a malfunction.
• The electronic shutter speed of this unit has been set to 1/50 [1/
60] second at the factory. If you use this unit under fluorescent
lamps in an area with the local power frequency of 60 [50] Hz,
switch the shutter speed to 1/120 [1/100] sec. (The sensitivity will
be degraded slightly at 1/120 [1/100] sec.) E type [U type]
• Lens aperture will be open when the electronic shutter is oper-
ated on AUTO mode with an auto iris lens in use, To avoid this, set
the shutter to any mode other than AUTO or use a manual (fixed)
iris lens.
• When the electronic shutter is set to the AUTO mode while this
unit is used under fluorescent lamp illumination, flickering may be
observed in the picture. This is a phenomenon caused by the rela-
tionship between the light’s power frequency and shutter speed,
and is not a malfunction.
