following two conditions: 

(1) this device may not cause interference, and 

(2) this device must accept any interference, including interference that may cause 

undesired operation of this device.

This transmitter must not be co-located or operated in conjunction with any other

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 user’s

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
