Dialling mode

The telephone can be operated in analogue exchanges (PULSE) as well
as new, digital exchanges (TONE/DTMF). The dialling mode is controlled
via the menu. Refer to Page 70 for the sequence of menu option selec-
tions.
Temporary tone dialling
If you only operate the telephone using the PULSE dialling mode, you can
still make use of the advantages of the TONE dialling mode (e.g.: remote
access of the answering machine in the telephone network). During a call,
you can temporarily switch to Tone dialling.
