Soft keys
Some keys on your radio may be customised to provide one-touch access to regularly used features.
These programmable keys are referred to as soft keys.
To activate the soft key function:
assigned to a programmable soft key, press and release
assigned to other keys (such as the Cancel/Home and Select/Send keys), press and hold for
one second
The following keys can be customised as soft keys:
the Select/Send key
the Cancel/Home key
the Emergency Button (if not assigned to Emergency operation)
the programmable side buttons
all radio keypad keys (1–9, *, 0, #,)
NOTE: During full-duplex PSTN/PBX calls, take care when trying to activate soft
keys (designated as 0–9,* and # keys) because they also generate DTMF tones.
There are many functions that can be assigned to a Soft key. Some functions are activated
immediately, such as the keypad lock/unlock or loudspeaker on/off. There are some special functions
that use a navigate to screen’ function. This means that on activation, a screen displays and you
need to take some additional action, such as activating a SmartMenu where you have to select an
option.
Context keys
Your radio has a left, centre and right context key which you use to select options displayed adjacent
to them.
Context labels appear at the bottom of the screen, directly above each context key. These labels
show the action of the key when it is pressed; either activating a feature or performing a function such
as clearing a call (Clear) or selecting an option (Select).
