Warning: Do not switch the phone on when wireless phone use is prohibited or when it may cause
interference or danger.

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.
