OPERATING THE TRANSCEIVER
USING ENCRYPTION
ENVOY® TRANSCEIVER GETTING STARTED GUIDE 103
Using encryption
You may have access to encryption/scrambling if these options are
enabled in your transceiver, and appropriate hardware fitted, if
required.
Switching the secure feature on or off
The 2220 Handset and 2230 Desk Console have a hot key that
accesses the secure feature directly. With the 2221 Handset, you
access the secure feature by pressing (Options), or via
(Functions) on the main menu screen. When you switch on
secure mode, all encryptors/scramblers that are activated in your
transceiver go secure. When AES-256 DV and data encryptors are
used at the same time, they use the same secure key.
If you want secure to remain on at all times, you set this in
Settings > Security > Secure Start State.
NOTE: For detailed information on setting up encryption
and scrambling, please see the Reference Manual
(Codan part number 15-04176-EN issue 7).
