(1) Any changes or modifications not expressly approved by the grantee of this device could
void the user's authority to operate the equipment.
(2) The modules FCC ID is not visible when installed in the host, or
(3) If the host is marketed so that end users do not have straight forward commonly used
methods for access to remove the module so that the FCC ID of the module is visible; then an
additional permanent label referring to the enclosed module: Contains Transmitter Module
FCC ID: AK81492549 or Contains FCC ID: AK81492549 must be used.
(4) This equipment must be installed and operated in accordance with provided instructions
and the antenna(s) used for this transmitter must be installed to provide a separation distance
of at least 20 cm from all persons and must not be co-located or operating in conjunction with
any other antenna or transmitter. End-users and installers must be provide with antenna
installation instructions and transmitter operating conditions for satisfying RF exposure
compliance.
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:
—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.
