The ZELOTES T-20 mouse features a unique vertical design for enhanced ergonomics and a total of six programmable buttons for versatile control.

Figure 1: ZELOTES T-20 Mouse Button Functions
- Left Button: Standard left-click function.
- Right Button: Standard right-click function.
- Middle Button (Scroll Wheel): For scrolling and middle-click actions.
- Forward Button: Navigates forward in web browsers or file explorers.
- Back Button: Navigates backward in web browsers or file explorers.

Figure 2: Ergonomic Comparison: Vertical vs. Horizontal Mouse
The vertical design of the ZELOTES T-20 allows your hand and wrist to rest in a more natural, handshake-like position. This posture reduces the twisting of the forearm and wrist, which is common with traditional horizontal mice, thereby minimizing strain and discomfort during prolonged use.
4. Setup
- Connect the Mouse: Plug the USB cable of the ZELOTES T-20 mouse into an available USB port on your computer.
- Driver Installation: The mouse is typically plug-and-play, meaning your operating system (Windows 2000/ME/XP(x64)/Vista/7/8 or Mac OS X over V10.4) should automatically detect and install the necessary drivers. If additional software or drivers are required for advanced customization (e.g., button remapping, macro settings), please visit the official ZELOTES website at http://www.zelotes.cn/en/ to download the latest drivers.
5. Operating Instructions
- Basic Movement: Move the mouse across a flat surface to control the cursor on your screen.
- DPI Adjustment: Press the dedicated DPI button (Button 6 as shown in Figure 1) to cycle through the available DPI settings: 1200, 1600, 2400, and 3200 DPI. This allows you to adjust cursor sensitivity to suit your task or preference.
- Navigation Buttons: Use the Forward (Button 4) and Back (Button 5) buttons for quick navigation in web browsers, file explorers, and other applications that support these functions.
- LED Lighting: The mouse features dynamic LED lighting. The lighting colors may cycle automatically or be fixed, providing an aesthetic enhancement to your setup.
6. Maintenance
To ensure the longevity and optimal performance of your ZELOTES T-20 mouse, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the surface of the mouse. For stubborn dirt, slightly dampen the cloth with water or a mild cleaning solution. Avoid using harsh chemicals or abrasive materials.
- Sensor Maintenance: Keep the optical sensor on the underside of the mouse clean and free from dust or debris to ensure accurate tracking.
- Cable Care: Avoid sharply bending or twisting the USB cable. Store the cable neatly when not in use to prevent damage.
- Mouse Pads: The mouse features durable Tieflon material pads for smooth gliding. Ensure your mouse pad or surface is clean to prevent excessive wear on these pads.
7. Troubleshooting
- Mouse Not Responding: Ensure the USB cable is securely plugged into your computer. Try connecting the mouse to a different USB port or a different computer to rule out port or system issues.
- Inaccurate Tracking: Clean the optical sensor on the bottom of the mouse and ensure your mouse pad or surface is clean and free of obstructions.
- Buttons Not Working: If specific buttons are not responding, ensure no software conflicts are present. Reinstalling drivers from the ZELOTES website may help.
- Backlight Issues: The LED backlight is typically automatic and cycles through colors. If the backlight is not functioning, check the USB connection. There is no software control for backlight customization mentioned.
