Event 70 - 79

Odometer Tracking & Flat Belt Replacement Event Codes:
Description
The flat belts require replacement every 100 million strides. The system keeps track of the accumulated
strides since the last belt replacement, and alerts the user that 100 million strides have elapsed and that it

was replaced, so a new feature was engineered to maintain the current odometer information after a board
replacement.
Event codes 70 through 79 are logged in the Error Log, but are really events and not errors. Event codes
70 through 77 are used to alert the unit that an upper or lower board has been replaced. The software
determines which board has been replaced and makes the odometer reading of the replacement board
