132  Encryption
The name of the encryption key that your radio is 
using for the transmission may briefly appear in 
the display.
While you are transmitting, the LED glows red and 
 appears in the display.
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.
Your radio may also remain muted if the currently 
selected channel has ‘proper key detect’ 
programmed.
Changing the radio’s encryption 
key
You may be able to use the Change All menu to 
change the encryption key that encrypts your outgoing 
calls. You can then use the Preset Keys menu to 
change the encryption keys back to the default 
encryption key for each channel.
