Using the DTMF Mode. Activating / deactivating DTMF
You want to be able to use your phone to control other equipment or to access certain services, such as
remote polling of an answering machine or telebanking. For these services you need the DTMF mode.
In the DTMF mode each key press generates a tone. If for example you key in a call number during a call,
your call partner will hear the tone signals.
Your system administrator will determine whether the DTMF mode should be generally activated or
deactivated.
If the DTMF mode is generally deactivated, you can use the *-key to activate it temporarily (and deactivate
it again) during the call. If the DTMF mode is generally activated (factory setting), the *-key does not have
any function during the call.
Situation You're in a call and the DTMF mode is generally deactivated. You want to
activate the DTMF mode temporarily.
If you already made a number of entries during the call, clear them first by
pressing the "C" key.
<long> To activate the DTMF mode temporarily: Press the *-key and hold it down
for a moment.
The display shows "DTMF _". You can now enter the DTMF characters.
Press the "Reset" Foxkey to reset the DTMF mode.
Note When you hang up, the DTMF mode is automatically deactivated.
