Encryption Key Deletion
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:
**00##
K Validity
From the main menu, select Security > K Validity.
K (Key) is a secret key the infrastructure uses to authenticate
the MTH800 in the system. It is part of the authentication that
provides service confidentiality between your MTH800 and
the system.
To verify K validity, press
Select. The display will show one of
the following messages:
•
K is Valid—the infrastructure can authenticate your
MTH800.
•
K is Invalid—the infrastructure shall not authenticate your
MTH800. Please call your Service Provider to restore K to
your MTH800.
CAUTION!
Using this feature will disable the terminal, and your Service Pro-
vider will need to re-enable the terminal.
Deletion should be performed in idle TMO/DMO or Emergency Operation.
