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.

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.

Your radio may be able to turn encryption on and off. 
While encryption is on, your outgoing calls are 
encrypted on channels programmed for encryption, 
and the encryption icon   remains in the display.

This setting only affects outgoing calls. Incoming calls 
will still be decoded by your radio so long as the key 
required to decode the call is stored in your radio.
