Authenticated Radio Disable

Authenticated Radio Disable is a standard feature in certain MOTOTRBO radios. This feature prevents a radio from being disabled by a Bad Actor.

Radio Disable is one feature supported by the majority of MOTOTRBO radios. This feature is useful to disable a lost or stolen radio, rendering it useless for the possessor to monitor radio communications. Similarly, someone with ill-intentions could use this feature to render radios inoperable.

Authenticated Radio Disable prevents the above by introducing a challenge-response mechanism. This means that in order to disable a destination radio, the source radio user needs to enter a passkey. If the passkey matches that which is provisioned into the destination radio, it will become disabled. If the passkey is no match, the radio ignores the received disable request.

Models Supported

Authenticated Radio Disable is standard in all ION; SL4010e; DP3xx1e; DP4000e and DM4000e series models shipped in EMEA after November 2019. Prior to this date, a SL4010e; DP3xx1e; DP4000e or DM4000e will need a CfS License. The same is true for the non-e SL4000; DP3xx1; DP4000 and DM4000 series. Authenticated Radio Disable is not available on lower tiered models (e.g. DP2400) or the first generation.

Configuration

Authenticated Radio Disable is mutually exclusive with (regular) Radio Disable in that only one can be enabled and used.

There are two options for the mode:

• User Authentication. The source radio user must enter the passkey.
• Device Authentication. The destination radio will be disabled if the passkey matches without the source radio user needing to enter the passkey.
