Usage such as switching the power ON/
OFF frequently could lead to failure of the
camera.
Handle this product with care.
Do not drop this product, nor apply shock or
vibration to the product. Failure to observe this

About the automatic status detection function
When this product malfunctions due to exoge-
nous noise, etc. for 30 seconds or more, the
product will automatically restart and will return
to normal state. When the product is restart,
initialization will be carried out as when the
power of the product is turned on. When the
product repeatedly resets, exogenous noise
level around the product may be high and that
may cause malfunction. Contact your dealer
for instructions.
Periodically images on the screen appear
to be distorted
When the camera is installed in a location
where it is subject to small vibrations (for exam-
ple, when it is installed near devices that
vibrate), images may appear distorted and
stretched lengthways. This phenomenon is a
characteristic of image pickup devices that use
CMOS sensors and is caused by the relation-
ship between the periodic movements of the
camera and the timing that the image sensor
reads images. This is not a problem with the
camera. To reduce the possibility of this phe-
nomenon occurring, install the camera in a
secure location.
About the ventilation opening
• This product has ventilation openings to
keep the inside of the camera at a low
humidity level.
• Depending on conditions such as temper-
ature, humidity or the climate, condensa-
tion may form and it may take time to
dehumidify.
