Antenna
This phone contains a built-in antenna. Use of antenna devices not marketed by Sony Ericsson specifically for this model could damage your cell phone, reduce performance, and produce SAR levels above the established limits (see below).
Efficient use
Hold your cell phone as you would any other cell phone. Do not cover the top of the cell phone when it is in use, as this affects call quality and may cause the cell phone to operate at a higher power level than needed, thus shortening talk and standby times.
Radio frequency (RF) exposure and Specific
Absorption Rate (SAR)
Your cell phone is a low-power radio transmitter and receiver. When it is turned on, it emits low levels of radio frequency energy (also known as radio waves or radio frequency fields). Governments around the world have adopted comprehensive international safety guidelines, developed by scientific organizations, for example, ICNIRP (International Commission on Non-Ionizing Radiation Protection) and IEEE (The Institute of Electrical and Electronics Engineers Inc.), through periodic and thorough evaluation of scientific studies. These guidelines establish permitted levels of radio wave exposure for the general population. The levels include a safety margin designed to assure the safety of all persons, regardless of age and health, and to account for any variations in measurements.
Specific Absorption Rate (SAR) is the unit of measurement for the amount of radio frequency energy absorbed by the body when using a phone. The SAR value is determined at the highest certified power level in laboratory conditions, but the actual SAR level of the cell phone while it is operating can be well below this value. This is because the cell phone is designed to use the minimum power required to reach the network.
