FCC Caution
This device complies with part 15 of the FCC Rules. O peration is subject to the following two conditions:
(1) This device may not cause harmful interferenc e, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Any Changes or modifications not expressly appro ved by the party responsible for compliance could void the user's
authority to operate the equipment.
Note: 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 int erference 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 i n a parti cular installation. If this equipment does cause harm ful
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 dif ferent from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV t echni cian for help.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .
This equipment should be installed and operated wi th minimum distance 20cm between the radiator & your body.
