Common questions about manuals, registration, and support for this brand.
Push the trackball out from the bottom of the mouse. Use a damp cloth to clean the trackball, inner housing, and sensor. Use a cotton swab to clean the dust on the white rollers. Do not use alcohol or alcohol wipes near the optical sensor to avoid damage.
First, check if the DPI button was accidentally pressed to a lower setting. You can cycle through the DPI settings. If the maximum DPI is still too slow, you will need to adjust the cursor speed directly in your computer's system mouse settings.
Use the included USB-C cable to connect the mouse to a standard 5V computer USB port. Do not use a high-power fast charger, as using an improper adapter may burn out the mouse's internal chip.
Press the DPI button on the mouse to cycle through the available levels (e.g., 200, 400, 800, 1200, 1600). The indicator light will flash a certain number of times to confirm which level is currently selected.
