Encryption 109
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.
Encrypting calls
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.
