Common questions about manuals, registration, and support for this brand.
Open the battery cover, insert the battery, and remove the USB nano receiver. Plug the receiver into a USB port on your computer and turn on the devices. They should connect automatically via the 2.4GHz band.
Use the multi-mode switch buttons (often labeled BT1/BT2). Short press to switch modes, and long press for 3 seconds to enter the Bluetooth pairing state until the indicator flashes. Then select the keyboard in your device's Bluetooth menu.
Ensure the batteries are properly installed and sufficiently charged. Unplug and replug the USB receiver, or try a different USB port. To reset the connection, refer to the manual for specific key combinations to re-pair the receiver.
Place the new remote near the receiver circuit. Press and hold the desired button on the new remote, then simultaneously press the corresponding button on your existing remote until the indicator light changes to confirm the signal is copied.
