- Step 1: Ensure the power switch on the electric riding vehicle is turned OFF.
- Step 2: On the remote control, simultaneously press and hold the "▲" (Forward) and "▼" (Back) keys for 3 seconds to initiate the matching code process. The first LED indicator on the remote will begin to flicker.
- Step 3: While the LED is flickering, turn ON the power switch on the electric riding vehicle.
- Step 4: The red indicator light on the remote control will stop flashing, indicating that the code matching is successful.
Note: This product has a memory function. Once successfully paired, you generally do not need to match the code again, even after replacing batteries.
