Activating/deactivating DTMF mode
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. 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.
You can specify whether the DTMF mode should be generally activated or deactivated
(see Chapter "Configuring the DTMF mode", page 77). DTMF is activated as the default
dialling mode.
If the DTMF mode is generally deactivated, you can activate it and deactivate it again
temporarily during a call.
You're in a call and the DTMF mode is generally deactivated. You want to
activate the DTMF mode temporarily:
DTMF
Press the DTMF Foxkey.
➔The display shows Enter number DTMF. You can now enter the DTMF charac-
ters.
Reset
Resetting DTMF mode:
Press the Reset Foxkey.
Note:
When you hang up, the DTMF mode is automatically deactivated again.
