■ Normal operating position
Use the phone only in its normal operating position.
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.
