Keep Your Trackball Rolling Smoothly
Is your trackball feeling sticky, jumpy, or less responsive? Over time, dust, oil, and dead skin cells build up inside the mechanism, causing the ball to drag or the cursor to skip. In this video, we’ll show you how to give it a proper clean. Regular maintenance restores that silky-smooth glide, ensures precise cursor control, and extends the life of your device. A few minutes of care makes all the difference!

Warm Tips for EM01 NL Wireless Trackball Mouse
The trackball mouse offers a distinctly different feel compared to traditional mice and may require some time to get used to. For first-time users, we recommend starting at 200/400 DPI and adjusting only once you feel comfortable.This product does not support horizontal scrolling (tilt function).This product is not recommended for tasks that demand extremely fine cursor control or high precision, such as image editing or CAD design.For users with smaller hands (measured less than 17.5 cm from the base of the palm to the center), the size of this product may be too large to hold comfortably.Please note that using a USB charging cable purchased separately may not charge the device. Always use the included USB cable.All the buttons are non-programmable and the backward forward buttons are not compatible with Mac OS system.

Precise Thumb Mouse: ProtoArc trackball mouse provides accurate and smooth tracking, allowing for easy navigation through documents and web pages. You no longer need to move your arm for the movement of the cursor. Your thumb will control the cursor instead via the trackball. It will effectively reduce fatigue and strain on your wrist and arm. More productive in the narrow space, such as the messy desktop, couch, bed etc. Note: this trackball mouse is not an ordinary traditional mouse.
Bluetooth & 2.4 G Wireless Connection: PLUG and PLAY. This trackball mouse has triple connection modes. You can control three devices at the same time, switch freely between PC, laptop and iPad with just one button to improve your efficiency.

Please remember to turn it off if you do not use it for a long time. 5 DPI levels (200/400/800/1200/1600) allows you to change the cursor sensitivity easily and track more smoothly
Quiet Clicking: Smooth frosted surface and quiet clicks can bring a better user experience and free your worry about bothering others and keep you stay focused while working.

After using the trackball for a period of time, please clean the trackball and the three white rollers inside the hole to ensure that the trackball is always smooth. Note: When the computer is just started or a large application is running, it may also cause the trackball to not run smoothly
Warm Tips: Since it takes a learning curve to get used to the control method when using our trackball mouse for the first time, it may cause inconvenience to your mouse grip, you can experiment with different hand positions to find what is most comfortable for you. We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort
