Receiving an encrypted call
When you receive an encrypted call, your radio unmutes
and you can hear clear speech, so long as the key
required to decode the call is stored in your radio.
The name of the encryption key used to encrypt the
incoming call may briefly appear in the display, below
the name of the caller:
If the key required to decode the call is not stored in
your radio, then your radio remains muted.
Note:
Your radio may also remain muted if the
currently selected channel has ‘proper key detect’
programmed.
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:
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 .
