To solve the problem, please refer to the following steps:
1. After turning on the mouse, press the Function button to switch to the 2.4GHz channel;
2. Press and hold the Left, Right and Function button for 3 seconds. When the Channel indicator blinks quickly, the 2.4GHz channel starts to pair, which will last for 3 minutes;
3. Insert the new receiver into the computer’s USB port. After the computer system detects and installs the driver and prompts that the device is available, bring the mouse within 30cm of the receiver. The indicator changes from blinking to always-on status, indicating that the pairing is successful and the device can be used normally.
