Threshold values written in NVRAM display:
where:
v x1 is the threshold for manual path
v x2 is the threshold for front path
v x3 is the threshold for rear path and rollers closed
v x4 is the threshold for rear path and rollers open
v x1, x2, x3, x4 are numbers in hexadecimal format corresponding to the threshold voltages with resolution
of 20 mV.
