First, fully charge the mouse, then turn it on and off, and re-pair according to the steps for different connection methods. It is also recommended to try another connection channel to see if it works.

Re-pairing methods:

• 2.4G re-pairing
  Remove the USB receiver, turn on the mouse switch, and briefly press the channel selection button on the bottom of the mouse to select the 2.4G channel (red light). Then, simultaneously press the left button, scroll wheel, and right button for 5-8 seconds. After releasing, observe the bottom laser light flashing rapidly, which indicates that the mouse has entered pairing mode. Quickly insert the USB receiver and place the mouse close to the receiver. The flashing will stop once the pairing is successful.
• BT re-pairing
  First, delete the Bluetooth connection record on the computer, then turn the mouse on and off. Briefly press the channel selection button to choose any Bluetooth channel (blue light). Long press the channel selection button for about 3 seconds until the corresponding channel indicator light flashes rapidly, indicating that the mouse has entered pairing mode. Then, go to the computer's Bluetooth list to find and connect to the mouse. The connection is successful when the channel indicator light stops flashing.

First, confirm whether the light behind the DPI is the power indicator light and whether it will stay on after the device is fully charged.

It is recommended to use another A-C charging cable to charge the device via a computer's USB port. Check if the device can be fully charged in 3-4 hours.

Note (Power Light Indicators):

• The power indicator light stays on red during charging.
• When the battery is low, the power indicator light will flash ten times at a frequency of once per second.
• After the device is fully charged, the power indicator light stays on green.

First, fully charge the device, then press the non-working button firmly for 5-7 seconds. Alternatively, connect the mouse to another device to see if it can work normally.

How to Adjust DPI Levels:

Adjust the DPI levels by briefly pressing the DPI button located at the back of the scroll wheel. There are a total of three levels.

DPI Indicator Light:

The DPI indicator light is the same as the 2.4G channel indicator light. You can also observe the power indicator light. If the white light flashes a certain number of times, it indicates which level the DPI has been adjusted to.
