United States & Canada
THIS PHONE MODEL HAS BEEN CERTIFIED IN COMPLIANCE
WITH THE GOVERNMENT'S REQUIREMENTS FOR EXPOSURE
TO RADIO WAVES.
The C6833 Series mobile phones have been designed to
comply with applicable safety requirements for exposure to
radio waves. Your wireless phone is a radio transmitter and
receiver. It is designed to not exceed the limits* of exposure to
radio frequency (RF) energy set by governmental authorities.
These limits establish permitted levels of RF energy for the
general population. The guidelines are based on standards
that were developed by international scientific organizations
through periodic and thorough evaluation of scientific studies.
The standards include a safety margin designed to assure the
safety of all individuals, regardless of age and health.
The radio wave exposure guidelines employ a unit of
measurement known as the Specific Absorption Rate (SAR).
Tests for SAR are conducted using standardized methods with
the phone transmitting at its highest certified power level in all
used frequency bands. While there may be differences
between the SAR levels of various phone models, they are all
designed to meet the relevant guidelines for exposure to radio
waves. For more information on SAR, please refer to the
Important information in the Setup guide from your phone.
The highest SAR value as reported to the authorities for this
phone model when tested for use by the ear is 1.102 W/kg*,
and when worn on the body is 1.009 W/kg*. For body-worn
operation, the phone has been tested when positioned a
minimum of 15 mm from the body without any metal parts in
the vicinity of the phone or when properly used with an
appropriate accessory and worn on the body. For devices
which include "WiFi hotspot" functionality, SAR measurements
for the device operating in WiFi hotspot mode were taken
using a separation distance of 10 mm. Use of third-party
