TIPS ON EFFICIENT
OPERATION: Your
phone has a built-in
antenna. As with
any other radio
transmitting device,
do not touch the
antenna unnecessarily when the
phone is switched on. Contact with
the antenna affects call quality and
may cause the phone to operate at a
higher power level than otherwise
needed. Not touching the antenna
area during a phone call optimises
the antenna performance and the
talktime of your phone.
