Frequently Asked Questions - Mydo 21871 TRUST
How do I connect the Trust Mydo 21871 mouse to my computer?
Insert one AA battery into the mouse, then plug the included nano USB receiver into an available USB port on your computer. The mouse will automatically pair and be ready to use within a few seconds. No software installation is required.
What kind of battery does the mouse use and how long does it last?
The mouse uses one standard AA battery (not included). Under typical usage, the battery can last up to 12 months. When the cursor becomes sluggish or the mouse stops working, replace the battery with a fresh one.
Can I change the DPI/sensitivity of the mouse?
The Trust Mydo 21871 has a fixed DPI of 1000, which is suitable for everyday tasks. There is no DPI switch or software to adjust sensitivity. If you need adjustable DPI, consider a different model.
My mouse cursor is jumping or not moving smoothly. What should I do?
First, check that the optical sensor on the bottom is clean and free of dust or debris. Wipe it gently with a dry cloth. Also, ensure you are using the mouse on a suitable surface (e.g., a mouse pad). Low battery can also cause erratic behavior—try replacing the battery.
How do I clean the mouse?
Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Do not use harsh chemicals or abrasive materials. Avoid getting moisture into the openings. For the sensor, use a dry cotton swab.
Is the mouse compatible with macOS or Linux?
Yes, the Trust Mydo 21871 works with Windows (7/8/10/11), macOS, and Linux because it uses a standard HID profile. It is plug-and-play on these systems; no additional drivers are needed.
The mouse stopped working. What can I do?
Check the battery: Replace it with a new one. Re-pair the receiver: Unplug the receiver, wait 10 seconds, plug it back in, and turn the mouse off and on. Try a different USB port. If the issue persists, the mouse may be defective; contact Trust support.
How do I store the nano receiver?
The mouse has a built-in compartment for the receiver. Open the battery cover, and you will find a slot to store the USB receiver securely when not in use. This helps prevent loss during travel.
Can I use the mouse while it is charging?
No, the Trust Mydo 21871 uses a disposable AA battery and cannot be recharged. You must replace the battery when it dies. Do not attempt to recharge the battery or the mouse.
What should I do if the scroll wheel is not working properly?
First, ensure there is no debris around the wheel. Gently clean it with a soft brush or compressed air. Check if the issue occurs in all applications—if only in one, the software may be the cause. Restart your computer. If the wheel is physically stuck, contact support.
