speaking

when you recall a
contact
Possible Solution
Be sure that your phone is switched on. Be sure that you are
accessing the network service. Be sure that you have not set an
incoming call barring option.
Be sure that you have switched off the loudspeaker. Be sure that you
are holding the phone close enough to your mouth. The microphone
is located at the bottom of the phone.
Check the signal strength indicator on the display. The number of
bars indicates the signal strength. Try moving the phone slightly or
moving closer to a window if you are in a building.
Use the phone book search feature to ensure the number has been
stored correctly. Resave the number, if necessary.
