I purchased this unit several years ago from a club that was going out of business. It has been a fantastic work out machine until today. This is the plug in version, not the 546i version.

I left it powered on for a couple weeks on accident and turned it off over the weekend. 

Today, when I turned it on, it begins the PRECOR banner message but only gets to PR and then displays 2 squares. No ne of the buttons work.

Any ideas on where to look?

I have a Q-Stress treadmill. The computer was damaged by high voltage. We replaced it, but I can't find the program. Can someone help me with a version for the treadmill? Please, I need help urgently.

So, during the exercise it is showing on the screen, for example 92 % MAX HR. However, when the report prints, it   reads, 79% MAX HR..... I am looking to see it there is a setting or something that can be changed to fix this so it     matches...
