Problem: Mouse does not work as expected (pointer jittery, jumpy, slow or fast;
mouse buttons not working properly).
Troubleshooting and problem resolution:
1. Change the mouse properties to adjust pointer movement speed.
2. Try using a different surface to see if the mouse's performance improves
(Recommend to use a mouse pad).
3. Turn the mouse over and check the sensor window. If there is any dust or
debris, clean the sensor window gently.
4. If multiple Bluetooth wireless devices are in use nearby, try turning them off to
see if performance improves.
