Every phone has a limited number of hard keys. Phone users, however, have a myriad of different priorities and preferences when asked which functions they use most often and which functionalities they would like to access quickly. Snom has therefore designed the function keys to be

programmable, even the preprogrammed "hard keys" whose default function is printed on them.


There are four types of programmable function keys


Context-sensitive, programmable function keys.

For the default settings , see "At a glance". You can select a different key event to be available on each respective key when the phone is in idle mode.

You cannot change the functions that are available when the phone is active, for example when you are in a call, when the phone is ringing, etc. Depending on the activity, different functions will be available.

See "Appendix 1 - Display Symbols and Icons" for the lists of symbols and their description.
