What do these codes mean when I start up my treadmill?
Hi all, I have an older keys 8800 treadmill. When I power it up 2 codes pop up on the digital display. They are usually different each time the unit is turned on. Today the codes were 873 & 3278. Where can I find out what exactly these codes mean? Keys is no longer in business and the manual for this model does not have that information. Thanks!
