You may have to purchase the belt from a Precor dealer in you area, if you don't have one then call Precor directly @ 1-800-347-4404 and they will help you. Most of these part have not hit the secondary market yet and Precor pretty much call the shots.

It doesn't always say low battery - check the battery first. If the battery is fine, then check the lower board and the incline motor.

You definitely can but you'll have to buy a 12V lead acid battery charger, the best option for a dead battery is just replacing it. With lead batteries there is a chance you'll get it to charge once and it'll just go dead again.

Hope this helps!

I would definitely check the battery first. The battery may not have enough charge to power everything plus the lift motor.

Here's a link to the various 546i models:

Drill it down on the left side under "narrow your search" and look for the serial number prefix. This will let you find all the correct parts and information specific to your model and serial number.

Probable Cause 1. A key is permanently depressed on the display.
2. An interface chip (IC) has failed in the upper PCA's keypad.
3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display.
Corrective Action
  1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
  2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
  3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

DO NOT PLUG THE DATA CABLE IN TO THE CSAFE PORT. It needs to be plugged into the 'lower board' port. Error 30 is a communication problem - check to see that the cable did not get damaged in the move. Hopefully you did not blow out the upper board by plugging it in incorrectly.
