FCC Warning:
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:
o Reorient or relocate the receiving antenna.
o Increase the separation between the equipment and receiver.
o Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
o Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications to this device not explicitly approved
by manufacturer could void your authority to operate this equipment.
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment complies with FCC radiation exposure limits set forth for
an uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator and your body.
This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.
