If the display stays at 1, then the UP button may be at fault, in which case you would need a new keypad.

This could be caused by either a bad lower electronic board or the brake/generator. I am attaching a link to the service manual for you for further reference. http://www.sportsmith.net/images/product_support/precor/Service%20Manuals/Commercial%20EFX/Service%20Manual,%20C546i%20Self%20Powered%20EFX.pdf

You can't with this type of trainer. You have to have a trainer where you can manually adjust the resistance. The closest you can do is shift your gearing.

Fluid trainers work by providing resistance that increases as your effort increases, much like riding on the road. There is not a switch or lever to increase the resistance with this specific trainer. So in short you have to put in a bigger effort to get more resistance. Putting in more effort and increasing your Cadence (rpm's) will provide a harder resistance and will decrease your duration attainable. This is OK. One of the benefits of using a trainer is that you can get more accomplished in less time.

I cannot get the timer to work on the olympus sport ascent cross trainer.

i too have this problem am under the impression there is a problem with the resistance but am waiting on areply from reebok technical support
