Try changing the batteries, insert the USB into a different port, unplug other inserted USB receivers, and then try to re-pair the product. Check if the light will flash normally during re-pairing.

Re-pairing steps:

• Keyboard: Remove the receiver, turn on the keyboard switch, and simultaneously press the ESC and Q keys for about 3-5 seconds. Once the power indicator light starts to flash rapidly, release the keys and quickly insert the USB (within 20 seconds). Place the keyboard close to the USB. The power indicator light will stop flashing when the connection is successful.
• Mouse: Remove the receiver, turn off the mouse switch, and simultaneously press the mouse wheel and right button for about 3 seconds. Then turn on the mouse switch. Note that you should not release the buttons immediately. After turning on the mouse switch, continue to hold the buttons for another 3-5 seconds before releasing. The indicator light between the left and right buttons will flash rapidly to indicate that the mouse has entered pairing mode. Quickly insert the USB (within 20 seconds) and place the mouse close to the USB. The indicator light will stop flashing when the connection is successful.
