option #41 sets battery voltage which should be either 72v or 80v
option #46 is battery voltage adjustment which has to be adjusted manually according to the actual battery voltage read by a voltmeter. This allows the display to set the proper voltage range according to the actual voltage from the battery.

when in this option range during setup you can move the direction lever to F or R to increase or decrease voltage increments by 0.01v +or- , and while the direction lever is in F or R you can depress the accelerator pedal to move the voltage increments by a factor of +10v or -10v.
F moves in + direction
R moves in - direction

once you have the correct battery voltage set on the display by what the voltmeter shows then you can exit out of the setup, cycle the power and everything should return to normal.

If you cannot get these settings to set going through the dash access then you will have to use the laptop program.
