Soft keys (dynamic function keys)

1.5.1

Principle

These are keys SK1 to SK5 (SK stands for Soft Key), located below the set display. By
convention, keys SK1 to SK5 are numbered from left (SK1) to right (SK5).
Soft keys are dynamic keys are keys whose function is determined by the system according to
the current operating or programming status. They cannot be programmed by the user.
Keys SK1 to SK5 are mainly used for telephone operation. The operation is enabled in the
system when the label is displayed on the screen. The attendant can activate the feature by
pressing the key corresponding to the label.
Pressing a key for which no label is displayed has no effect; this helps avoid inadvertent
activation of features.
The dynamic keys are also used to:
- Implement operating features (callback, text messaging, etc.).
