undesired operation of this device.
This transmitter must not be co-located or operated in conjunction with any other
antenna or transmitter. The Bluetooth antenna cannot be removed (or replaced) by
user. This equipment complies with FCC/ IC radiation exposure limits set forth for
an uncontrolled environment and meets the FCC radio frequency (RF) Exposure
Guidelines and RSS-102 of the IC radio frequency (RF) Exposure rules. This
equipment has very low levels of RF energy that it deemed to comply without
maximum permissive exposure evaluation (MPE). But it is desirable that it should
be installed and operated keeping the radiator at least 20 cm or more away from
person's body (excluding extremities: hands, wrists, feet and ankles). Alteration
or modifications carried out without appropriate authorization may invalidate the

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 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:
□ Relocate or reorient 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
