Radio Wave Exposure and
Specific Absorption Rate (SAR)
Information
United States & Canada
THIS PHONE MODEL HAS BEEN CERTIFIED IN
COMPLIANCE WITH THE GOVERNMENT'S
REQUIREMENTS FOR EXPOSURE TO RADIO
WAVES.
The SO-04D 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 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 0.74 W/kg*, and when
worn on the body is 0.72 W/kg* for speech
and 1.07 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 Mobile Communications
AB 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 accessories may result in
different SAR levels than those reported.
