Antenna
Use of antenna devices not marketed by
Sony Mobile Communications Inc. could
damage the phone, reduce performance,
and produce SAR levels above the
established limits. Do not cover the antenna
with your hand as this affects call quality,
power levels and can shorten talk and
standby times.

Radio Frequency (RF) exposure and
Specific Absorption Rate (SAR)
When the phone or Bluetooth handsfree is
turned on, it emits low levels of radio
frequency energy. International safety
guidelines have been developed through
periodic and thorough evaluation of
scientific studies. These guidelines establish
permitted levels of radio wave exposure.
The guidelines include a safety margin
designed to assure the safety of all persons
and to account for any variations in
measurements.
Specific Absorption Rate (SAR) is used to
measure radio frequency energy absorbed
by the body when using a mobile phone.
The SAR value is determined at the highest
certified power level in laboratory
conditions, but because the phone is
designed to use the minimum power
necessary to access the chosen network,
the actual SAR level can be well below this
value. There is no proof of difference in
safety based on difference in SAR value.
Products with radio transmitters sold in
the US must be certified by the Federal
Communications Commission (FCC). When
required, tests are performed when the
phone is placed at the ear and when worn
on the body. For body-worn operation, this
phone has been tested and meets the FCC
RF exposure guidelines. Please use an
accessory designated for this product or an
accessory which contains no metal and
which positions the handset a minimum of
1.5 cm from the body.

frequency exposure, go to:
