8.11. SPEAKER MUTE
The speaker mute function key will mute the audio output to the speaker. Pressing the

8.12. MAN DOWN
The Man Down function provides support for the radio’s automatic alarm sequence to
be executed if the radio’s inbuilt accelerometer senses certain unusual patterns in the
orientation and movement of the radio.
The detection process uses an orientation “learning” period, immediately after the
man down function is enabled, to establish how the radio is normally held.
Once this is established, any significant and prolonged deviation from this orientation
or an unexpected acceleration is considered to be an alarm event.
The radio also senses normal walking movement. If this stops for a period of time, this
is also considered an alarm event.
Once the Man Down function is triggered, a warning beep will sound and the operator
has a set time to disarm the sending of an Alarm Status using a programmed “Man
Down” button (see buttons).
The Man Down system sequence is:
• The radio’s man down system is enabled by pressing the allocated Man Down
button.
