exchanges
If you have connected your telephone to a PBX, you can use all the special functions such
as call forwarding and automatic call-back. These can be accessed using the "R" button.
For a PBX, a FLASH time of 90 ms (FLASH 1, factory setting) or 250ms (FLASH 2) is
required (Adjustment, see 8.11). To check whether your telephone will function correctly
with your PBX, consult the supplier of the PBX.
7.1 Using
Pause
With private exchanges, it is necessary to dial a certain number (e.g. "9" or "0") in order to
obtain a dialling tone for an outside line on the extension. With some, older private
exchanges, it takes some time before the dialling tone can be heard. Especially for these
private exchanges, an automatic pause can be inserted after connecting to the outside line
so that you can dial directly without waiting for the dialling tone.
Entering a pause when dialling manually
Press the redial button
once between the number for the outside line and the actual
telephone number. After connecting to an outside line your telephone will wait for 3 seconds
before dialling the actual telephone number.
The pause can also be saved with numbers in the phone book.
