Man Down
Man Down is a licensed customisable feature which uses motion sensors to detect motion in three
dimensions. When your radio is powered on it stores it's current angle of inclination (orientation). If it
moves more than a customised angle from the original inclination or is stationary for more than a
customised length of time, the radio sounds an alarm and displays a Man Down Alarm message. In
other words the radio can detect conditions indicating that you have become incapacitated. If you do
not respond to the alert within a customised time period, your radio initiates a Man Down Emergency
and takes action depending on its customisation.
Although Man Down is intended to increase the chances of incapacitated users being detected, you
should not regard it as a substitute for compliance with appropriate risk assessment and other safety
procedures and practices. Do not entrust your safety to the Man Down Alarm.
Test the Man Down Alert and Alarm regularly to ensure they are functioning correctly.
Once started the Man Down Alarm sounds either until you switch it off or until the battery runs down.
Ensure that the battery is charged regularly and check that it has as much charge as possible before
activating Man Down.
Man Down is disabled if the radio is placed in a car kit or charger.
The Man Down feature may be customised so that you do not have access to the following:
—the soft key On/Off toggle or a user profile to switch the feature on and off;
—the Man Down screen to select the sensor or combination of sensors used as described below.
To toggle Man Down on/off:
1. Activate Man Down using one of the following methods:
Press a customised soft key to toggle Man Down on. The sensors activated are those
set in Man Down options on the next page.
Select a user profile which uses Man Down (see User profiles on the previous page).
The sensors activated are those customised in the profile.
From the Home screen, press the Shortcut context key, then select the Man Down
icon.
A message (‘Man Down Starting’) is displayed and an alert sounds (a succession of beeps).
2. Attach your radio in a comfortable wearing position on your body. When a two second
continuous tone finishes the radio’s ‘normal wearing position has been recorded. An icon
indicates that Man Down is switched on and which sensors are active.
To deactivate Man Down, either select a user profile which does not use Man Down, or press the
customised soft key to toggle Man Down off.
