Sepura SC21 Series User Manual

Cancelling false alarms
If the active sensors detect a possible ‘Man Down’ situation the Man Down Alert is sounded and a
Man Down Alert message is displayed on the screen. If you are safe (that is, this is a false alarm) you
need to switch off the alert, otherwise a genuine Man Down Emergency situation is considered to
have occurred and—depending on the customisation of your radio—various automatic actions are
initiated. For example, an Emergency Status message may be sent to a pre-defined destination.
To switch off the Man Down Alert (false alarm situation):
press a designated key (which is different from the soft key used to switch Man Down on and
off) or
move the radio vigorously for a short period of time (if customised).
For example shake the radio up and down or sideways, or tap it, or (if the radio is clipped to
your belt) move your hips rapidly from side to side.
After the Man Down Alert is switched off your radio may be customised to start recording and storing
the current position and/or angle to use as the new ‘steady’ position.
Man Down options
1. Press Menu then select Applications > Man Down.
2.
Select the Man Down sensors to use: Motion & Tilt sensors, Motion Sensor only, or
Tilt Only sensor.
If you enable Man Down from a User Profile, the Man Down Settings screen updates to reflect the
sensors defined as active in the Profile.
Lone Worker
If you are working alone you can use the Lone Worker feature to let your dispatcher know that you
are safe.
When Lone Worker is enabled your radio periodically sounds an alert which you must
acknowledge—usually by pressing a pre-programmed key—otherwise the radio can be
programmed to send either, or a combination of, emergency status, emergency call, and GPS
position.
To enable Lone Worker, scroll to a user profile which has Lone Worker enabled, then press the
Select context key. See User profiles on page94.
To disable Lone Worker mode, repeat the process and choose a different user profile.
