What to do when "Kill All Locked" appears on your H3 radio?

If you have two H3 radios, please press "*" on your other H3 radio to turn on DTMF, enter the "activation code + #" you set, and then press the PTT button to send it. For example: the Kill/Stun code is 12345, and the unlock code is 12345# (Add the # as unlock code, no need to set it)

But if you only have one H3 radio, please click HERE to view video tutorial the video operations on the frequency writing software. Download address click HERE. Click HERE to buy view or buy H3 radio.


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 unscrupulous persons.

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.

The Stun-Kill-Revive functions provide a safety feature to prevent its unauthorized use.
