This setting is done with the GE LX Handset
Master controller (MRCl) maintains the truck hour meter. If MRC1 is replaced, the truck hour meter reading can be programmed into the replacement controller by adjusting function codes 29 and 30. Function code 29 maintains the 1 ‘s and 10’s location while function code 30 maintains the 100’s and location. (i.e. A function code 29 setting of 15 and ‘1000’s a function code 30 setting of 20 displays an hour meter reading of 2015.)
