You can find more details here.

• USB receiver: Plug the receiver to a USB port and open Logitech Options. In

Options, select Add devices > Setup Unifying device, and follow the

instructions.

MagSpeed adaptive scroll-wheel

The speed-adaptive scroll wheel shifts between two scrolling modes automatically. As

you scroll faster, it will automatically shift from line-by-line scrolling to free-spinning.

• Line-by-line (ratchet) mode — ideal for precise navigation of items and lists.

• Hyper-fast (free-spin) mode — near-frictionless spinning, letting you fly through

long documents and web pages.

Switch modes manually

You can also manually switch between modes by pressing the mode shift button.

By default, mode shift is assigned to the button on top of the mouse. Use the Logitech

Options Software, to disable SmartShift if you prefer to stay in a single scrolling mode

and shift manually. You can also adjust the SmartShift sensitivity, which will change

the speed required to automatically shift into free spinning.

Thumb wheel

Scroll side to side effortlessly with a stroke of your thumb.

Install Logitech Options software to extend thumb wheel capabilities:

• Adjust thumbwheel scrolling speed, and direction

• Enable app-specific settings for the thumbwheel:

• Zoom in Microsoft Word and PowerPoint

• Adjust brush size in Adobe Photoshop

• Navigate your timeline in Adobe Premiere Pro

• Switch between tabs in the browser

• Adjust volume

• Assign custom keystrokes to the wheel rotation (up and down)

Gesture Button

You can use gestures for desktop navigation, app management, pan, zoom, and more.

You can assign up to five different actions to the Gesture button. Or map gestures to

other MX Master buttons, including the middle button or manual shift button.

Back/Forward buttons

Conveniently located, the back and forward buttons enhance navigation and simplify

tasks.

To move back and forward:

• Press the back or forward button to navigate web or document pages, depending

on the location of the mouse pointer.

NOTE: On the Mac, enabling of the back/forward buttons requires installation of

Logitech Options software.

Install Logitech Options software to unlock new capabilities for the back/forward

buttons.

In addition to enabling the buttons for use with Macs, Logitech Options software lets

you map other useful functions to the buttons, including undo/redo, OS navigation,

zoom, volume up/down, and more.

App-Specific Settings

Your mouse buttons can be assigned to perform different functions for different

applications. For example, you can assign the thumb wheel to do horizontal scrolling

in Microsoft Excel and zoom in Microsoft PowerPoint.

With Logitech Options, you can install predefined app-specific settings that adapt the

mouse button behavior to be optimized in selected applications.

The following app-specific settings have been created for you:

With these settings, the Gesture button and the wheel mode-shift button are keeping

Flow

With Logitech Flow, you can work on multiple computers with a single MX Master 3.

You can use the mouse cursor to move from one computer to the next. You can even

copy and paste between computers, and if you have a compatible Logitech Keyboard,

such as MX Keys, the keyboard will follow the mouse and switch computers at the

same time.

You will need to install Logitech Options software on both computers and follow

these instructions.

Battery

Charge mouse battery:

Connect one end of the provided charging cable to the USB-C port on the mouse and

the other end to a USB power source.

A minimum of 3 minutes charging gives you enough power for a full day of use.

Depending on how you use the mouse, a full charge can last up to 70 days.

NOTE: Battery life may vary depending on user and operating conditions.

Check mouse battery status:
