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.

example, when your phone is in your bag.

Unlock
 and then 
 within 1.5 seconds to
