How to revert to the previous release of software

The following procedure describes how to revert to the previous release of
software, Feature Set, Customer data and ISM Parameters using the Undo
Installation option.
This option requires that the same Software Delivery (PCMCIA) card that
was used to upgrade this Option 11C Compact be installed and used to revert
it to its former database. The Software Delivery (PCMCIA) card must not
have been used to upgrade a subsequent Option 11C Compact, since the
Security ID will no longer match this system.
Note: When upgrading, the existing Option 11C Compact database is
saved (backed-up) on the Software Delivery (PCMCIA) card. The card
contains only the backed-up database and Security ID of the last Option
11C Compact with which it was used.
Summary of steps
The steps to revert to the previous database are summarized in the following
list. They consist of:
• Checking to make sure the correct Software Delivery (PCMCIA) card is
installed.
• Selecting the Utilities menu.
• Selecting Undo Installation option.
• Reverting to the previous database.
