Guidelines for safe and efficient use
Please read this information before using your PC300 Mobile BroadbandPC Card.
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 PC300. Use
of unauthorised or modified antennas could damage your PC300 and may violate regulations, causing
loss of performance and SAR levels above the recommended limits (see below).
Efficient use
Do not cover the antenna when in use, as this affects call quality and may cause the PC300 to operate
at a higher power level than needed, thus shortening talk and standby times.
Radio Frequency (RF) exposure and SAR
Your PC Card is a low-power radio transmitter and receiver (transceiver). 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 organisations, e.g. ICNIRP (International Commission on Non-Ionising 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 transceiver. The SAR value is determined at the highest certified
