Accessing Functions

... With Codes

You can activate the functions of your system by
entering codes such as:
qmk DND (do not disturb) on.
rmk DND (do not disturb) off.
All codes to activate or enable functions are always
introduced by pressing the star key, and all codes to
deactivate, disable or delete functions are always
entered starting with the pound key.
An alphabetically ordered overview of all functions and
their corresponding codes can be found in the
Appendix (Quick-Reference Operating Instructions).

... With Function Keys

Functions for which a key has been set up can be
accessed directly as follows.
Press the "consultation hold" key. The function is
executed, provided this is possible in the current
situation.
If your service personnel has changed the default
assignments and saved functions on keys in ac-
cordance with your requests or requirements,
you can execute these functions by pressing the
appropriate keys.
