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 airbag.
• Do not attempt to disassemble your product. Only Sony Ericsson authorized
personnel should perform any service.
Antenna
Only use an antenna that has been specifically designed by Sony Ericsson for your
mobile phone. Use of unauthorized 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 Com-
mission on Non-Ionizing Radiation Protection) and IEEE (The Institute of Electri-
cal and Electronics Engineers Inc.), through periodic and thorough evaluation of
scientific studies. These guidelines establish permitted levels of radio wave expo-
sure 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 certi-
fied 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 meets FCC RF
exposure guidelines when the handset is positioned a minimum of 15 mm from the
body without any metal parts in the vicinity of the phone or when used with the
original Sony Ericsson body worn accessory intended for this phone. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.
A separate leaflet with SAR information for this mobile phone model is included
with the material that comes with this mobile phone. This information can also be
found, together with more information on radio frequency exposure and SAR, on
www.SonyEricsson.com.
