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.
