We have a Bodyguard T340 treadmill. There is an error message to service the belt. The belt and table have been lubricated and the belt turns freely. The treadmill will not run, it has been turned on and off and the power has been disconnected trying to reset the error message. I do not have a manual. Looking for a manual online has shown many manuals saying they are for the T340 but all have different displays and once the manual is accessed they make no mention of the T340!! Do you know how to reset this model?
