If you use more than one handset with the base station, here are a few special
hints.
Internal or external call?
When you receive a call, there is a different ring signal for internal and exter-
nal calls:
• An internal ring signal has a two-second signal followed by a four-second
pause.
• An external ring signal is the same as usual.
During an internal call, the number of the caller’s handset is displayed.
You can set the tune of the ring signal for internal and external calls yourself.
This makes it easier for you to recognize the ring signal of your own handset.
For more information, please read “Ringer tones or melodies” on page 42.
Call back
The base station calls you back when you transfer an external call to another
handset without waiting for an answer but the third party does not respond
within 30 seconds.
You can select different ring signals when being called back by the base sta-
tion. For more information, please read “Ringer tones or melodies” on
page 42.
To make an internal call, you use the
INT key on the handset. If you receive an
internal call, the number of the caller appears in the left-hand side of the dis-
play. If the caller’s number is included in your handset phone book, the corre-
sponding name appears instead.
