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.
