Some two-way radios have a 3 unique functions called ‘stun’, ‘kill’
and ‘revive’ which are used in situations where the radio has been lost
temporarily or stolen. These functions can disable and enable the device
remotely and are used to prevent the unauthorized use of the device by
If a 2-way radio has been lost, the user can send remote ‘stun’
signals from a second radio to the lost radio to inhibit all the
functions of the device making it practically unusable. The two way
radio can neither receive nor transmit any messages over any of the
channels if it has received a ‘stun’ signal.
Once the lost radio has been re-located, the device can be enabled
again by sending the ‘revive’ signal from another device to lost radio,
re-activating all its functions.
If a two-way radio is deemed to have been permanently lost, then the
user can send ‘kill’ signals from another device to the lost radio
permanently disabling all its functions. Such a ‘killed’ radio, if
recovered at a later time, can only be re-activated after re-programming
its internal circuitry.
Stun-Kill-Revive functions provide a safety feature to prevent its
