Can't set om controller from mm to inch.

[rgrow1]

The battery went dead on our old mill with om control. I cleared the control and reloaded all parameters and diagnostics (we had these backed up)
Everything appears to be working fine except I cannot change the system to inches. Using the handy page setting, it will not change from 0 to 1, with or without pwe enabled.
When I input G20 in mdi, it gives me alarm 10 (invalid G code)
Any thought from the experts here?

Please check you have the option parameter switched on 900 bit5

Am I not mistaken or can't you just press the Offset key, go to the Setting page and change the relevant option from mm to inch?
