Just came across an old style (separate power supply, which I don't have) ProS 6x7 power back. How do you set up the back for 120, the pressure plate currently says 220? Are there different pressure plates? I removed the pressure plate thinking maybe you just reversed the plate but that doesn't work. Thanks in advance.

Memory fading but yes they had two plates with 120 and 220 text, think there was a plastic box to protect the one not in the back.

The back can be used without the power supply using the lever.
