(Currently does not support infrared photos and NFC functions; cannot play fitness ring) The handle is connected to the console and the charging method is as follows: Insert the left and right handles into the left and right guide rails on the left and right sides of the Switch console. After inserting, you will hear a locking sound (accompanied by messages). Connect and identify the handle insertion. Disconnect Bluetooth connection and Bluetooth return: If the handle is disconnected in the Bluetooth connection state, you can short press the sync button on the guide rail to disconnect the Bluetooth connection of the handle, and the handle will be in a dormant state. Long press the sync button on the handle for 3 seconds, and you will see the player number lights on the horse running, then press any button (except the 3D button) on the handle (except 3D buttons). Handle Bluetooth connection: Disconnect the two handles from the console (press the guide rail lock key before you can pull out the handle). After disconnecting, the handle will automatically enter the Bluetooth connection mode. The player number light will stop the horse race and light up the LED light (the number of lights and the position of the lights represent the handle channel number corresponding to the Bluetooth connection), and at the same time the four LEDs on the Bluetooth connecting handle. The light green square grid is the same as the corresponding player's handle number light. When the Bluetooth connection is OK, the handle can be used for related game operations. The Bluetooth reception distance is normally 8~10 meters. Due to different lighting, a certain amount of color error is allowed.
