This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15  
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a  
residential installation. This equipment generates, uses, and can radiate radio frequency energy, and if not installed  
and used in accordance with the instructions, may cause harmful interference to radio communications. However,  
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful  
interference to radio or television reception, which can be determined by turning the equipment off and on, the user  
is encouraged to try to correct the interference by one or more of the following measures:  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  
• Consult the dealer or an experienced radio/TV technician for help.  
To assure continued FCC compliance, the user must use grounded power supply cord and the provided  
shielded video interface cable with bonded ferrite cores. If a BNC cable is going to be used, use only a  
shielded BNC(5) cable. Also, any unauthorized changes or modifications not expressly approved by the  
party responsible for compliance could void the user's authority to operate this device.
