• If you are not sure of your dialing
system, set the unit to tone dialing.
Make a trial call. If the call connects,
leave the setting as is; otherwise set
the unit to pulse dialing.

tones in certain situations during a call,
you may switch over to tone dialing

the handset to the base to register. You
must re-register the handset before you
