Product Care and Maintenance
Your mobile phone is a highly sophisticated electronic device. To get the
most out of your mobile phone read this text about product care, safe and
efficient use.
Product care
• Keep your mobile phone dry.
• Avoid exposing your mobile phone to extreme hot or cold
temperatures.
• Avoid placing your mobile phone close to lit candles, cigarettes, naked
flames or any heat source.
• As with all sophisticated electronic devices rough treatment could
damage your mobile phone.
• Only use a soft damp cloth to clean your mobile phone.
• Do not paint your mobile phone as the paint could obstruct the
earphone, microphone or any moveable parts and prevent normal use.
• Do not attempt to disassemble your mobile phone, a broken warranty
seal will void the warranty. The phone does not contain consumer
serviceable components. Service should only be performed by
Certified Service Partners.
• Only use Ericsson original accessories. Failure to do so may result in
loss of performance, damage to the phone, fire, electric shock or
injury, and will void the warranty.
• Treat your mobile phone with care, keep it in a clean and dust free
place.
Antenna Care
• To avoid impaired performance please ensure your mobile phone’s
antenna is not bent or damaged.
• Do not remove the antenna yourself. If your phone’s antenna is
damaged please take it to a Certified Service Partner.
• Unauthorised antenna modifications, or attachments could damage the
phone and may violate the appropriate regulations causing loss of
performance and radio frequency (RF) energy above the
recommended limits.
Efficient Phone Operation
To enjoy optimum performance with minimum power consumption
please:
• Hold the phone as you would any other telephone. While speaking
directly into the mouthpiece, angle the antenna in a direction up and
over your shoulder. If the Globalstar antenna is deployed, it should be
vertical during a call.
• Do not hold the antenna when the phone is in use. Holding the antenna
affects call quality, may cause the phone to operate at a higher power
level than needed and shorten talk and standby times.
Guidelines for Safe and Efficient Use
General
Your mobile phone is a radio transmitter and receiver. When the phone is
turned on, it receives and transmits radio frequency (RF) energy.
Depending on the type of mobile phone you possess, it operates on
different frequency ranges and employs commonly used modulation
techniques. The system that handles your call when you are using your
phone controls the power level at which your phone transmits.
Exposure to Radio Frequency (RF) Energy
The International Commission on Non-Ionising Radiation Protection
(ICNIRP), supported by the World Health Organisation (WHO),
published during 1996 a statement and in 1998 guidelines which set
