Using Long Key
The long key function supports system features and defines a long key press to digits
between 0-9. The long key press can be defined as speed dials
or as predefined MSF
signals.
MSF signals are system dependent. The MSF signal is sent to a server and not a specific
number. If supported by the subscribed system, an MSF signal sent to the system could for
example return system features to the handset. Contact your system administrator for more
information.
Speed dials are phone calls. For speed dials you can define Push to talk, meaning that
talking requires pressing left softkey while talking. When not pressing the left softkey you are
muted. For more information, see "Handset Keys" on page 16.
Note:
The long key function is not related to Alarm features.
