Using the 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 or telebanking. For these services you need the DTMF mode.
When DTMF is activated, you hear a tone every time you press a key. When you make a call, DTMF is
automatically activated: If you enter a phone number while in a call, your call partner will also hear the
tones.
You can deactivate the DTMF mode in the configuration mode using "OFF". DTMF is then deactivated as
default. You can then use the *-key to activate and deactivate the DTMF mode during a call. If DTMF is
activated in the configuration mode using "ON", you cannot deactivate it during a call using the *-key.
Unlocking the Phone for One Call
You want to make a call on a phone that is locked or restricted for chargeable calls, for example a corridor
phone or a phone in a meeting room.
Authorized subscribers can activate such phones so they can make one chargeable call. To do so, you will
need your own phone number and a PIN. Any call charges incurred will be charged to you on a "user
pays" basis.
Situation
DTMF is deactivated in the configuration mode using "OFF".

During the call you can activate and deactivate the DTMF mode by repeat-
edly pressing the *-key and holding it down for a moment.
