Upgrading your hardware
Upgrading your system's software
Adding new modules (optional)
Programming your upgraded system for BRI
Backing Up Your System's Programming
To backup your existing system's programming, you need to run the backup
program from the System Programming and Maintenance (SPM) utility. Verify
that your backup was successful and that you have all the necessary records
reprogram the system.
For more information on how to back up your MERLIN LEGEND system, refer to
the System Programming and Maintenance Guide (555-620-1 42).
