How do I upgrade the RAM on the F1-style main board of a biometric F-Series HandKey?

The following technical note describes in detail the process for upgrading a biometric F-Series HandKey or a biometric F-Series HandPunch F1-style main board with additional RAM.  Please note that the F1 style main board has dip switches rather than a reset button.

Note: A RAM upgrade on a biometric hand reader will erase the user database of existing hand templates. Save existing hand templates before proceeding with the RAM upgrade instructions.
