The MX Master 3S can be paired with up to three different computers. Use the Easy-Switch button (No. 9) on the bottom of the mouse to effortlessly switch between connected channels.
6.2. MagSpeed Adaptive Scroll Wheel
The scroll wheel (No. 1) automatically switches between two scrolling modes based on your scrolling speed:
- Ratcheted (Click-to-Click) Mode: Ideal for precise navigation of items and lists.
- Free-Spinning (Hyper-Fast) Mode: Offers nearly frictionless scrolling for quickly navigating long documents and web pages.
You can manually switch scroll wheel modes by pressing the Wheel Mode Toggle Button (No. 2) located on the top of the mouse.
6.3. Thumb Wheel
The thumb wheel (No. 5) allows for horizontal scrolling with a slight flick. Install Logitech Options+ software to extend its functionality, including:
- Adjusting scrolling speed and direction.
- Enabling application-specific settings (e.g., zoom in Microsoft Word/PowerPoint, brush size in Adobe Photoshop, timeline navigation in Adobe Premiere Pro, tab switching in browsers, volume control).
- Assigning custom keystrokes to the wheel rotation.
6.4. Gesture Button
The gesture button (No. 3) can be used to perform various actions. Hold the gesture button and move the mouse left, right, up, or down. These gestures can be customized via Logitech Options+ for functions such as desktop navigation, application management, and panning. You can assign up to five different actions to the gesture button.
6.5. Back/Forward Buttons
The back (No. 11) and forward (No. 12) buttons are conveniently located for enhanced navigation efficiency. Press them to navigate back or forward between web pages or document pages (the action depends on the mouse pointer's location).
Note for Mac users: Logitech Options+ software is required to enable these buttons and unlock additional functions like undo/redo, OS navigation, zoom, and volume control.
6.6. Darkfield 8000 DPI Sensor
The MX Master 3S features an 8000 DPI Darkfield sensor for precise tracking on virtually any surface, including glass. By default, the mouse operates at 1000 DPI.

7. Charging and Battery Status
7.1. Charging Your MX Master 3S
To charge your mouse:
- Connect one end of the provided USB-C charging cable to the USB-C port (No. 7) on the mouse.
- Connect the other end to a USB power source (e.g., computer USB port, wall adapter).
A 3-minute charge provides a full day of use. A full charge can last up to 70 days, though actual battery life varies depending on user and operating conditions.
7.2. Checking Battery Status
The three LED indicator lights (No. 6) on the side of the mouse display the battery status:
- Green: 100% to 10% charge remaining.
- Red: 10% charge or less remaining.
- Flashing Green: The mouse is currently charging.
Install Logi Options+ software to receive battery status notifications, including low battery warnings, directly on your computer.
8. Maintenance
8.1. Cleaning the Device
To clean your MX Master 3S mouse, use a solution containing 70% isopropyl alcohol and 30% water. This is similar to common cleaning solutions. Avoid using other types of alcohol as they can cause damage. The CDC does not recommend using bleach for cleaning this device.
9. Troubleshooting
- Bluetooth Connection Issues: If you encounter problems connecting via Bluetooth, ensure the mouse is in discoverable mode (LED flashing rapidly). If issues persist, refer to the Logitech support page for detailed Bluetooth troubleshooting information.
- Mouse Not Responding: Check if the mouse is powered on and fully charged. Try connecting via the LOGI BOLT receiver if you are using Bluetooth, or vice-versa, to rule out connection method issues.
- Cursor Movement Irregularities: Ensure the sensor is clean and free from debris. If using on a reflective surface, the Darkfield sensor should still work, but try a different surface if problems occur.
