Issue
When my FR3000/4000 powers off due to power interruption, I need the Remote Button to remain enabled on Power Up.

Resolution
Assign the programmable button as a "Lock" key in Key & Display window. With this key assigned as Lock, it will cause the Remote key feature to retain its state after power up.
