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.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- 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. User should avoid un-intended operation of usage when it is collocated with other transmitters or antenna.
Specific Absorption Rate (SAR) information
This Walkie talkie meets the government’s requirements for exposure to radio
waves. The guidelines are based on standards that were developed by
independent scientific organizations through periodic and thorough evaluation
of scientific studies.
The standards include a substantial safety margin designed to assure the
safety of all persons regardless of age or health. FCC RF Exposure Information
and Statement the SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of
tissue. Device types: Walkie talkie has also been tested against this SAR
limit. This device was tested for typical body-worn operations with the back
of the handset kept 25mm from the body. To maintain compliance with FCC RF
exposure requirements, use accessories that maintain an 25mm separation
distance between the user’s body and the back of the phone. The use of belt
clips, holsters and similar accessories should not contain metallic components
in its assembly. The use of accessories that do not satisfy these requirements
may not comply with FCC RF exposure requirements, and should be avoided.
