Using a Password
q
If you forget the system password, you will not be able to use your
computer. To regain access, it is necessary to disconnect the back-up
battery for an extended period. This operation should only be performed
by an authorized Texas Instruments dealer. Any other attempt to
perform this operation could result in damage that will void the
warranty and is not recommended.
Note: Always make a note of the password you installed incase you forget it. Store the
password note in a secure place away from where you store or operate your computer.
