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.

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 symbol

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.

To turn encryption on or off:
