Operating Manual 
8.3  Lens Filter 
The CC640 camera is equipped with an IR cut filter on its lens. This is threaded 
onto the front of the lens and is required to filter out near-infrared light that can 
have an undesirable affect on the images. It is recommended that the filter always 
be left installed on the lens.

9.  Maintenance 
The CC640 requires little maintenance and no calibrations. Keeping the camera 
clean and in a dry environment is important for the longevity of the camera. 
 
9.1  Lithium Battery 
The Camera is equipped with a Lithium Thionyl Chloride Battery. The battery 
maintains the clock functionality for periods when power is not connected to the 
camera. The expected battery life is 2 years. If the camera is in operation and 
connected to a power supply, the battery life may be extended up to 10 Years.  
It is recommended that the battery be replaced by a certified repair facility. The 
sticker on the bottom of the camera indicates the date of battery installation.
