Specic Absorption Rate (SAR) certication

information

Your device conforms to U.S. Federal Communications

Commission (FCC) standards that limit human exposure to radio

frequency (RF) energy emitted by radio and telecommunications

equipment. These standards prevent the sale of mobile devices

thatexceedamaximumexposurelevel(knownastheSpecic

Absorption Rate, or SAR) of 1.6 W/kg.

During testing, the maximum SAR values recorded for this model

were:

1. When used with accessories that contain no metal and provide at least 1.5

cm separation between the device (including the antenna, whether extended

or retracted) and the wearer’s body.

In normal use, the actual SAR is likely to be much lower, as the

device has been designed to emit only the RF energy necessary

to transmit a signal to the nearest base station. By automatically

emitting lower levels when possible, your device reduces your

overall exposure to RF energy.

The FCC has granted an Equipment Authorisation for this model

device based on the compliance of all reported SAR levels with

the FCC RF exposure guidelines. The authorisation can be found

ontheFCCOfceofEngineeringandTechnologywebsiteat

www.fcc.gov/oet/ea (search for grantee code A3L and product

code GTC3750)
