Function Description
Switches the control panel on/off.
When the control panel is turned on, the key is highlighted in
green.
In the case of an error the key will blink red.
Provides the standby operation to save energy.
By pressing this button, the standby is activated, and the button is
highlighted in orange.
While in standby, the brightness of the display’s backlight is
driven down to a defined value (configurable in the “Setup” page,
s. 6.4.2.8), but the system continues monitoring the
corresponding (emergency) frequency. The display will be turned
on again if an event occurs (e.g., signal level rises above squelch
level, alarm occurs, scan algorithm finds an active frequency).
Pressing any button will return the system from standby to normal
operation mode (the function of the pressed button will not be
executed).
The volume adjustment button contains two keys (+ and -).
Pressing any of the two keys opens a dialog for adjusting the
internal and external speakers (s. 6.5.2).
Switches the volume off/on (mute function).
