Adjustable DPI Settings
The mouse features 4 adjustable DPI levels (600/1200/1600/3200) to control cursor speed and sensitivity. Press the DPI button on the mouse (located near the scroll wheel) to cycle through the available DPI settings. Choose the DPI that best suits your activity, whether for precise graphic design or fast-paced browsing.

Programmable Buttons and Side Roller
The Rapoo MT750S mouse is equipped with 8 programmable buttons, including a unique side scroll wheel. These buttons can be customized using the Rapoo driver software to perform various functions, such as basic commands, media controls, Windows functions, and advanced features. The side scroll wheel allows for horizontal scrolling, which is highly efficient for applications like AutoCAD, Revit, Excel, and Adobe graphic editing software.

Laser Tracking Technology
The MT750S utilizes a high-performance laser engine, allowing it to track accurately on virtually any surface, including glass or high-gloss surfaces, where traditional optical mice may struggle. This provides superior precision and responsiveness.

Maintenance
Charging the Mouse
The Rapoo MT750S features a built-in 800mAh Li-ion rechargeable battery. To charge the mouse, connect the included USB-B cable to the charging port on the front of the mouse and plug the other end into a USB power source. A full charge takes approximately 3 hours and can last up to 30 days with typical use. The mouse has a super long standby time. A low battery indicator (flashing red light) will remind you when charging is needed.

Cleaning
To clean your mouse, use a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals or abrasive materials, as these can damage the mouse's surface.
Troubleshooting
- Mouse not responding:
- Ensure the mouse is powered on.
- Check battery level and charge if necessary.
- For 2.4G connection, ensure the USB receiver is securely plugged in. Try a different USB port.
- For Bluetooth connection, ensure Bluetooth is enabled on your device and the mouse is paired correctly. Try re-pairing the mouse.
- Try restarting your computer/device.
- Cursor movement is erratic or imprecise:
- Clean the laser sensor on the bottom of the mouse.
- Ensure you are using the mouse on a suitable surface. While the laser mouse tracks on many surfaces, extreme textures or highly reflective surfaces can sometimes affect performance.
- Adjust the DPI setting to a lower value if the cursor is too fast.
- Cannot switch between devices:
- Ensure all desired devices are properly paired or connected (2.4G receiver plugged in).
- Short press the device switching button firmly.
- Buttons not working or programmable features not active:
- Ensure the Rapoo driver software is installed and up to date on your computer.
- Verify button assignments within the driver software.
