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.
