DPI Adjustment
The mouse has a maximum sensitivity of 2000 dpi. While there isn't a dedicated DPI switch mentioned, sensitivity can typically be adjusted through your operating system's mouse settings for personalized control.
Maintenance
Cleaning
- Wipe the mouse surface with a soft, dry cloth.
- For stubborn dirt, lightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid harsh chemicals.

Troubleshooting
- Mouse not responding:
- Check if the power switch on the bottom of the mouse is ON.
