Warning
This device complies with Part 15 of the FCC Rules 
and Industry Canada licence-exempt RSS 
standard(s).
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 of the device.
This transmitter must not be co-located or operated 
in conjunction with any other antenna or 
transmitter.
Under Industry Canada regulations, this radio 
transmitter may only operate using an antenna of a 
type and maximum (or lesser) gain approved for 
the transmitter by Industry Canada. To reduce 
potential radio interference to other users, the 
antenna type and its gain should be so chosen that 
the equivalent isotropically radiated power (e.i.r.p.) 
is not more than that necessary for successful 
communication.
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.

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.
You are cautioned that any changes or 
modifications not expressly approved in this 
manual could void your authority to operate this 
equipment.
