What's in the Box

Charging the Mouse
Before initial use, it is recommended to fully charge your MX Master 3S mouse. Connect the supplied USB-C charging cable to the USB-C port on the front of the mouse and to a USB power source (e.g., computer USB port, USB wall adapter). A full charge provides up to 70 days of power, depending on usage.
Connecting Your Mouse

Using the Logi Bolt USB Receiver
- Plug the Logi Bolt USB receiver into an available USB port on your computer.
- Turn on the mouse using the power switch on the bottom.
- The mouse should automatically connect to the receiver. The LED indicator on the mouse will turn solid green.
Using Bluetooth Low Energy
- Turn on the mouse using the power switch on the bottom.
- Press and hold one of the Easy-Switch buttons (1, 2, or 3) on the bottom of the mouse until the LED indicator for that channel starts blinking rapidly. This indicates pairing mode.
- On your computer or device, open Bluetooth settings and select "Logitech MX Master 3S" from the list of available devices to pair.
- Once connected, the LED indicator will turn solid green for 5 seconds.
