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 safe and efficient use
chapter in the User Guide.
The highest SAR value as reported to the authorities for this
phone model when tested for use by the ear is 1.30 W/kg*, and
when worn on the body is 0.61 W/kg* for speech and 0.95 W/kg*
for data calls. Body worn measurements are made while the phone
is in use and worn on the body with a Sony Ericsson accessory
supplied with or designated for use with this phone. It is therefore
recommended that only Ericsson and Sony Ericsson original
accessories be used in conjunction with Sony Ericsson phones.
