If encryption is on and you receive a clear call (unencrypted),
the MTH800 will display a Call & Data Not Encrypted
message.
You cannot manually disable Air Encryption (if fitted) from the
menu. This sub-menu only indicates if Air Encryption is enabled
at that moment.
The Air Encryption feature is ONLY enabled depending on your
Service Provider.

Please check with your Service Provider whether the
terminal is provided with air interface encryption keys.
You can delete the air interface encryption keys from the
terminal by entering the following sequence from the keypad:
* * 0 0 # #
Deletion should be performed in idle TMO/DMO or Emergency
Operation.
Using this feature will disable the terminal,
and your Service Provider will need to re-
enable the terminal.
