Sound
You can adjust the volume of the speaker and increase the sensitivity of the microphone (see
Whisper mode on page22) so that you can speak more quietly. Your radio also uses sound to alert
you to the various operational states.
Adjusting the volume
Rotate the Navi-knob to adjust the volume. A vertical volume meter displays to indicate the current
volume level. The radio sounds an audible tone at the new volume level.
Muting audio
Soft keys may be customised to mute the audio output of loudspeakers and earpieces connected to
the radio or consoles. In an installation with two consoles connected, audio devices can be muted on
the local and remote console.
Individual soft keys may be customised specifically to:
Mute the primary loudspeaker(s) connected to the radio
Mute the secondary loudspeaker(s) connected to console(s)
Mute all connected loudspeakers and earpieces, including Bluetooth devices
Pressing the same soft key again will cancel the mute and restore audio to the previous volume
levels.
An icon is displayed on the status line to indicate the current audio mute mode:
