Product Line
Power logic P1

Environment
2.E.22 or newer
_____________________________________________________________
Root Cause
From the version history in P1 manual, we can see that in 2.E.22 firmware, our R&D team “add enable soft-switch of the keys O/I on front-panel in menu;” and the default value is “disable”, it means when this “control keys mode” setting is “disable”, the I/O key on front panel is not working, we need to modify the “control keys mode” setting to “No confirm” or “with confirm” to use the I/O key.

Solution
Modify the “control keys mode” setting to “No confirm” or “with confirm” to use the I/O key on front panel.
