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.
