● OVERVIEW
CAUTION
These servicing instructions are for use by qualified service personnel only.
To reduce the risk of electric shock do not perform any servicing other than
that contained in the operating instructions unless you are qualified to do so.
The BNC output port is used to monitor the installation process of the
network camera.
If you keep the BNC cable connected, a risk of lightening may cause damage
or malfunction to the product.
Please use the input power with just one camera and other devices must not
be connected.
Precautions about the operating temperature
The product does not work in an ambient temperature of below -50˚C.
Defrosting may not work at below -50˚C depending on the installation place.
Keep the product powered at all times so that the temperature inside the product stays over
-10˚C.
Even when you warm up the product by up to -20˚C after leaving it at below -50˚C, the prod-
uct does not output the video signal and just displays the blue screen for 30 minutes before
resetting the zoom module, during which the product does not work normally.
Then, it tries to initialize the lens module every 30 minutes until the temperature inside the
product increases to the normal operating temperature.
