How to access batter on kettler condor elliptical machine?

Maybe there is something interfering with the difficulty plus button it may be stuck. try holding the difficulty minus and see it that hold it level and if it increases when you release its a faulty button.

I have had a lot of success searching manufacturer's websites for User's Manuals. Nearly all have them online in PDF format, A second source would be the Sears PartsDirect website.

Check for a small adapter hole on the bottom side of the keypad/control console.

Do you still have your manual? I kind of remember running into this, I think it was something simple( sorry I can't recall!) like lubrication or uneven alignment (fixed by adjusting the feet). I don't see the condor on the kettler USA site, but they still may be able to help.

Here's what I posted for someone else, I had to change my batteries this morning:
If you look behind the unit, (directly behind the digital readout) you'll see a small rectangular inset, if you look up in that (I used my cell phone light), you'll see a tab that you can pry with a screwdriver gently to release the computer section. Just keep one hand on top, when you pry it you'll feel the unit pop up, then you can lift it out. It takes 2 AA batteries, thankfully not some bizarre disk batteries :)
Btw when you look at the readout, you'll notice it's set in a silver square- that square is the computer module that pops out.
Hope this helps!
