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 0.60 W/kg*, and when
worn on the body is 1.06 W/kg* for speech
and 1.44 W/kg* for data calls. 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 Sony Ericsson accessory and
worn on the body.
For devices which include "WiFi hotspot"
functionality, body-worn SAR measurements
for operation of the device operating in WiFi
hotspot mode were taken using a separation
distance of 10mm.
Use of third-party accessories may result in
different SAR levels than those reported.
** Before a phone model is available for sale
to the public in the US, it must be tested and
certified by the Federal Communications
Commission (FCC) that it does not exceed
the limit established by the government-
adopted requirement for safe exposure*. The
tests are performed in positions and locations
(i.e., by the ear and worn on the body) as
required by the FCC for each model. The
FCC has granted an Equipment Authorization
for this phone model with all reported SAR
levels evaluated as in compliance with the
FCC RF exposure guidelines. While there
may be differences between the SAR levels
of various phones, all mobile phones granted
an FCC equipment authorization meet the
government requirement for safe exposure.
SAR information on this phone model is on
file at the FCC and can be found under the
Display Grant section of http://
transition.fcc.gov/oet/ea/fccid/ after
searching on FCC ID PY7A3880087.
