Operating Instructions
Using the Elliptical Peddler:

Using the Digital Monitor:
- The digital monitor automatically activates when you begin pedaling.

- Use the SCAN function (if available, typically a button on the monitor) to cycle through these metrics automatically, or press the button to manually select a specific display.
- To reset the monitor, typically press and hold the button for a few seconds, or remove and reinsert batteries.
