About the antenna
Your Nokia phone has a
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.
