Lone Worker
A operating function of a radio, associated with a user
profile, that allows a user working alone to indicate that
they are safe. When the user selects the Lone Worker
profile, the radio will periodically emit an audible alert.
Each time the user hears the alert he or she must press a
key on the keypad to prevent an alert being triggered. If
no key is pressed within a given time, the radio will send
an Emergency Status message will to a customised
location, for example to the Dispatcher. It can be
configured to send an emergency call or GPS co-
ordinates if an emergency situation is detected. See also
