To pair your hand controller, first attach the magnet key of the board leash into its fitting on the back of the board.
Then, press the controller throttle all the way down for up to 5 seconds until the LED lights begin to flash. When the lights stop flashing, the controller is paired with the board.
When the magnet key is connected to its fitting on the back of the board, the jetpack is on and the steady LED lights show the state of charge of the board battery.
The hand controller adjusts the speed and acceleration of the jetboard via an easy-to-use thumb throttle. Apply pressure to go faster, and release pressure to slow down.
In order to ride the jetboard, the magnet key—attached to your leg via the velcro board leash—must be connected into its fitting. Should you fall off the board while riding, the board leash will pull the magnet key off and the board will automatically stop.
When the magnet key is disconnected from its fitting on the back of the board, the jetpack is off and the blinking LED lights show the state of charge of the hand controller.
Note that latest firmware update for your hand controller are made available under "Your Hand Controller" on the home screen of the app. Here's a tutorial on how to update the hand controller.
