FCC Exposure to Radio Frequency (RF) Signals
For Handset
This is a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for
exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S.
Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy
for the general population. The guidelines are based on the safety standards previously set by both U.S. and
international standards bodies. These standards include a substantial safety margin designed to assure the
safety of all persons, regardless of age and health. This device and its antenna must not be collocated or
operating in conjunction with any other antenna or transmitter. This product has been shown to be capable
of compliance for localized specific absorption rate (SAR) for uncontrolled environment/general population
exposure limits specified in ANSI/IEEE Std. C95.1-1992 and had been tested in accordance with the
