The elevation function is not working properly.
- Unplug the treadmill from the outlet. Wait approximately 60 seconds, allowing the lower board to discharge built-up energy.
- Remove the motor cover.
- Verify that there are no lights lit on the lower circuit board (this indicates built-up energy has discharged and it is safe to check it).
- Verify that all wires are securely and correctly placed on the lower circuit board, especially the large wire harness on the top of the circuit board with 12 different colored wires coming out of it.
- Double check that all connections are secure, especially the console cable. Unplug and reconnect the console cable at the top of the console mast – see the assembly instructions in the owner’s manual for this step.

Can’t acquire/read heart rate.
- Good contact with the grip is essential. Before taking pulse, stop walking and step on side rails and place hands on contacts.
- Try gripping the handlebar contacts over the top, with your thumb next to your index finger instead of gripping it with your thumb under the handlebars.
- Verify that there are no lights lit on the lower circuit board (this indicates built-up energy has discharged and it is safe to check it).
- Contact heart rate grips are not intended for continuous reading. Rather, try holding the grips for 10-20 seconds at a time for an accurate reading.
- Static electricity can damage the heart rate grip receiver and/or grips and cause either an “HR” or no reading at all.
- Refer to the product manual that came with your machine for more information on the heart rate function.
