About the antenna
Your Nokia phone has a fixed-length antenna. Do not attempt 
to extend or remove it.
Normal position
Hold the phone as you would any other telephone, with the 
antenna pointed up and over your shoulder.
Tips on efficient operation
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.
Checking signal strength
Your phone operates on radio waves. Radio signal coverage 
is maintained by a wireless network, and the quality of calls 
on your phone depends on the strength of the wireless radio 
signal.
