Logitech® Wireless Mouse M545

The Logitech® Unifying receiver

Plug it. Forget it. Add to it.

Your new Logitech product ships with a Logitech® 

Unifying receiver. Did you know you can 

add a compatible Logitech wireless device 

that uses the same receiver as your current 

Logitech Unifying product? 

Are you Unifying-ready?

If you have a Logitech wireless device that’s 

Unifying-ready, you can pair it with additional 

Unifying devices. Just look for the orange 

Unifying logo on the new device or its packaging. 

Build your ideal combo. Add something. 

Replace something. It’s easy, and you’ll use only 

one USB port for up to six devices. 

Getting started is easy

If you’re ready to pair your device(s) via Unifying, 

here’s what you need to do:

1. 

Make sure your Unifying receiver is plugged in.

2. 

If you haven’t already, download the Logitech® 

Unifying software from www.logitech.com/

unifying.

3. 

Start the Unifying software* and follow the 

onscreen instructions to pair the new wireless 

device with your existing Unifying receiver. 

*Go to Start / All Programs / Logitech / Unifying / 

Logitech Unifying Software

Help with setup:  

Mouse not working

•  Is the mouse powered on?
•  Is the Pico receiver securely plugged into 

a computer USB port? Try changing USB ports.

•  If the Pico receiver is plugged into a USB hub, 

try plugging it directly into a USB port on 

your computer.

•  Try moving the Pico receiver to a USB port 

closer to the mouse.

•  Remove metallic objects between the mouse 

and the Pico receiver.

•  Check the orientation of the battery inside 

the mouse. Replace the battery if necessary. 

The mouse uses one AA alkaline battery.

•  Try reconnecting the mouse and Pico receiver 

using the Logitech Unifying software. 

(Refer to the Unifying section in this guide.)

•  If other USB 3.0 devices are in use, try plugging 

Pico receiver into other USB port at a distance.
