1. Take out the receiver from the mouse.
2. Place the receiver into a PC or laptop USB port.

After you unplug and replug the USB receiver, within 30 seconds, turn off the mouse and then turn it on with the left key pressed.

It is not possible to provide a replacement receiver for this product.
This is because during production the product and the Nano USB receiver (dongle) are assigned a unique code, so the product can only communicate with the bundled original receiver. This production process is also performed for security reasons.

The USB receiver is stored inside the battery compartment of the mouse. The special receiver storage compartment is located there so you can always store the dongle safely when not in use to prevent damage or loss.

1. Use a mousepad or a piece of paper to check if the surface may be the reason.
2. Try using the mouse on a different surface.
3. Clean the sensor on the bottom of the mouse with a dry cloth.

1. Move other active wireless devices away from the mouse and the USB receiver.
2. The PC can not respond immediately because the CPU is under full load.
3. Try changing the battery.

1. Make sure the device is turned on.
2. Make sure the USB receiver is plugged into the PC/ laptop’s USB port.
3. If the PC/ laptop cannot initially recognize the USB receiver, please replug the receiver.
4. Check if the battery is installed correctly.
5. In case of a low battery, please try changing the battery.
6. Move other working wireless devices away from the mouse and the USB receiver.
7. Please keep away from walls or big objects because this may reduce the range.
