About encryption

The encryption feature is available for digital and 

dual-mode channels only.

To make communications with other users on your 

system completely private, your radio may be able to 

encrypt outgoing calls, using a confidential encryption 

key. The radio receiving your call must have the same 

encryption key installed before it can hear your 

encrypted call.

About the proper key detect feature

Your radio may be programmed with ‘proper key detect’. 

This means that you can only hear an encrypted call if 

the key used to encrypt the incoming call matches the 

key used to encrypt your outgoing calls on that channel.

Note that encryption does not need to be turned ‘on’ for 

the radio to unmute.

For example, you are encrypting your outgoing calls 

using encryption key 7. Although key 1 and key 2 are 

also stored in your radio, your radio has been 

programmed so that it will only unmute for incoming 

calls encrypted using key 7.
