Threshold values written in NVRAM display:
Cx1 Fx2 Rx3(x4)
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.
