114 Guidelines for Safe and Efficient Use
• 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.
• Only use an antenna that has been specifically designed for your phone.
Unauthorized antennas, 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.
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 antenna is extendable/retractable, it should be extended
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. If your mobile phone is
equipped with an infrared eye, never direct the infrared ray at anyone’s eye
and make sure that it does not disturb any other infrared units.
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.
