Radio Frequency (RF) exposure and Specifi c 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 scientifi c 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.
Specifi c 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 certifi ed
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 certifi ed 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, 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.
