Guidelines for Safe and Efficient Use
Please read this information before using your GC89.
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 GC89. Use of
unauthorised or modified antennas could damage your GC89 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 GC89 to operate
at a higher power level than needed, thus shortening talk and standby times.
