5. Setup

5.1 Battery Installation

The ATXB8 remote control requires batteries for operation. It is compatible with 18650 Li-ion cells (2x) or other suitable power sources within the 4V-9V range.

1. Locate the battery compartment on the underside of the remote control.
2. Open the battery compartment cover.
3. Insert the batteries, ensuring correct polarity.
4. Close the battery compartment cover securely.

5.2 Receiver Binding

To establish communication between the ATXB8 remote control and the ARX88 receiver, a binding process is required.

1. Ensure both the remote control and the receiver are powered off.
2. Connect the binding plug (usually included with the receiver) to the "BIND" port on the ARX88 receiver.
3. Apply power to the receiver. The receiver's LED should flash rapidly, indicating it is in binding mode.
4. While holding down the bind button on the ATXB8 remote control (refer to the remote's diagram for exact location), power on the remote control.
5. The remote control's display should indicate "Binding..." or a similar message.
6. Once the receiver's LED becomes solid, the binding process is complete. Power off both the receiver and the remote control.
7. Remove the binding plug from the receiver.
8. Power on the remote control first, then the receiver, to confirm successful binding. The receiver's LED should be solid.
