- Prepare the Treadmill: Ensure your treadmill is powered on.
- Unplug Safety Lock: Locate and unplug the safety lock (or safety key) from the treadmill's console. This action typically causes the treadmill display to show an error message or enter a pairing mode.
- Initiate Pairing: Within 10 seconds of unplugging the safety lock, point the remote control directly at the display window of the treadmill.
- Press and Hold: Simultaneously press and hold down one of the "Start/Pause" buttons (either top button) on the remote control for approximately 3 seconds.
- Confirmation: Listen for an audible beep from the treadmill. A beep indicates that the pairing process was successful.
- Re-insert Safety Lock: Once paired, re-insert the safety lock into the treadmill console. The treadmill should now be ready for operation with the remote control.
Note: If pairing is unsuccessful, repeat the steps, ensuring the remote is pointed directly at the display and the buttons are held for the specified duration.
4. Operation
After successful pairing, you can use the remote control to operate your treadmill.
- Starting the Treadmill: Press either of the top "Start/Stop" buttons. The treadmill will typically start at a low speed.
