Guidelines for Safe and Efficient Use
Please read this information before using your mobile phone.
Note Important: to avoid hearing impairment, answer call or lower volume before
placing this product to your ear.
Recommendations
• Always treat your product with care and keep it in a clean and dust-free place.
• Do not expose your product to liquid or moisture or humidity.
• Do not expose your product to extreme high or low temperatures.
• Do not expose your product to open flames or lit tobacco
products.
• Do not drop, throw or try to bend your product.
• Do not paint your product.
• Do not use your product near medical equipment without
requesting permission.
• Do not use your product when in, or around aircraft, or areas posted "turn off
two-way radio".
• Do not use your product in an area where a potentially explosive
atmosphere exists.
• Do not place your product or install wireless equipment in the
area above your car's air bag.
• Do not attempt to disassemble your product. Only Sony Ericsson
authorised personnel should perform service.
Antenna
Only use an antenna that has been specifically designed by Sony
Ericsson for your mobile phone. Use of unauthorised or modified
antennas could damage your mobile phone and may violate regulations, causing
loss of performance and SAR levels above the recommended limits (see below).
Efficient use
Hold your mobile phone as you would any other phone. Do not cover the top of the
phone when in use, as this affects call quality and may cause the phone to operate
at a higher power level than needed, thus shortening talk and standby times.
Radio Frequency (RF) Exposure and SAR
Your mobile 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, e.g. 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 mobile phone. The SAR
value is determined at the highest certified power level in laboratory conditions,
but the actual SAR level of the mobile phone while operating can be well below
this value. This is because the mobile phone is designed to use the minimum power
required to reach the network.
Variations in SAR below the radio frequency exposure guidelines do not mean that
there are variations in safety. While there may be differences in SAR levels among
mobile phones, all Sony Ericsson mobile phone models are designed to meet radio
frequency exposure guidelines.
Before a phone model is available for sale to the public, it must be tested and
certified to the 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 (that is, at the ear and worn on the body) as required by the
FCC for each model. For body worn operation, this phone has been tested and
