SYSTEM BOOTS UP OKAY, BUT DISPLAY KEYS DON’T RESPOND
Electrical interference or noise could cause this problem. Make sure the IB and the Display Head each have a
good ‘Earth Ground’ and the ground/shield between the IB and Display Head is connected. Try to find the source
by turning on and off motors/pumps and other equipment in the area. Make sure this equipment is well grounded.
