TIPS ON EFFICIENT OPERATION: Your phone has two
internal antennas (blue areas in the picture). As with any
other radio transmitting device, do not touch the antennas
unnecessarily when the phone is switched on. Contact with
the antennas 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.
