Per Lippert:
SETTING ZERO POINT
Before “AUTO-LEVELING” or utilizing the TOUCH PAD as the level indicator for MANUAL LEVEL, the LEVEL ZERO POINT must be set. This process is done initially at the factory but may need to be done again in the event of loss of power or the owner wishes to reset level.
MANUALLY LEVEL the coach. Turn the TOUCH PAD “OFF”. Turn the TOUCH PAD “ON” again. This readies the TOUCH PAD for reprogramming the LEVEL ZERO POINT.
Push the “FRONT” button 5 times
Push the “REAR” button 5 times.
All lights on TOUCH PAD will now flash and the buzzer will be off. The TOUCH PAD is now in IDLE MODE.
Push the “RETRACT ALL” button 3 times. The “WAIT” light will flash. This sets LEVEL ZERO POINT.
When the “WAIT” light goes off, the “LCI LOGO” will flash waiting for the operator to chose which mode to level the coach with, “MAN” or “AUTO.”
