USING

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

• Is the keyboard powered on?
• Is the Unifying receiver securely plugged into a computer USB port? Try changing USB ports.
• If the Unifying receiver is plugged into a USB hub, try plugging it directly into a USB port on your computer.
• Did you pull the battery tab? Check the orientation of the batteries inside the keyboard, or replace the two AAA alkaline batteries.
• Remove metallic objects between the keyboard and its Unifying receiver.
• Try moving the Unifying receiver to a USB port closer to the keyboard, or go to www.logitech.com/usbextender for a USB extender that will allow the receiver to be placed closer to the keyboard.
• Try reconnecting the keyboard and Unifying receiver using the Logitech Unifying software (Refer to the Unifying section in this guide.)

• When using cleaning sprays, spray the cloth and wipe — do not spray the device directly. Never submerge the device in a liquid, cleaning or otherwise.
• Don’t use bleach, acetone/nail polish remover, strong solvents, or abrasives. See above warning!

Cleaning Keyboards

• To clean the keys, use regular tap water to lightly moisten a soft, lint-free cloth and gently wipe down the keys.

COVID-19

Logitech encourages users to properly sanitize their products in accordance with guidelines put out by the World Health Organization and the Centers for Disease Control guidelines.

**Wireless product not working properly when also using a USB 3.0

device**

When using a USB 2.0 2.4GHz wireless peripheral device (such as a mouse, keyboard, or headphones) with a PC that also has a USB 3.0 peripheral device plugged in, you may experience erratic operation caused by interference. This is especially likely to happen when using USB 3.0 remote hard drives or flash drives.

This interference may result in:

• Delayed response to mouse or keyboard inputs
• Missing keyboard characters or mouse commands
• Decreased operating distance between the USB 2.0 wireless device and its receiver

There are some techniques that can help early adopters of USB 3.0 to mitigate potential problems with their existing 2.4GHz wireless devices:

• If your PC has multiple USB 2.0 connectors available, separate your USB 3.0 and USB 2.0 receivers by as much distance as possible. For example, if your PC has a choice of USB 2.0 connectors, use the one on the opposite side of the PC from the USB 3.0 connector.
• Position your USB 2.0 receiver as close as possible to your wireless peripheral (mouse, keyboard, headphones, etc.).
• Use a standard, USB-extender cable to position your USB 2.0 wireless receiver as far away as possible from your USB 3.0 connector.

A USB-extender cable is available for Logitech customers who are experiencing this problem (click here for more information).

NOTE: A USB 3.0 connector sometimes referred to as Super Speed USB or SS, normally has a blue plastic insert in the connector. Unlike a USB 2.0 connector which has 4 pins within the connector, a USB 3.0 connector has 9 pins.

Move your USB 2.0 wireless receiver to the opposite side of your computer:

Make sure your USB 2.0 wireless receiver is in the USB 2.0 connector closest to your wireless peripheral:

Use a USB extended cable to position your wireless receiver as far away from your USB 3.0 peripheral as possible:

Windows 8 and Windows 10 product support and device compatibility

To check if your Logitech product works with Windows 8 or Windows 10, first select the appropriate product category from the list below.

• Mice and keyboards
• Tablet and laptop accessories
• Gaming products
• Harmony remotes
• Speakers
• Headphones and headsets
• Smart radios
• Squeezebox network music players
• Alert security cameras
• WiLife security cameras
• Webcams

US, US International and United Kingdom keyboard layouts

See the following for generic English-language keyboard layouts:

• US

• US International 

• United Kingdom

• • Operating distance between the mouse or keyboard and USB receiver

In an ideal environment, a Unifying or non-Unifying device can operate up to 30 feet (10 meters) away from its receiver (shown below) in a clear line of sight.

If you’re not getting this distance, try these suggestions:

  * Replace the battery/batteries or make sure your mouse or keyboard is fully charged
  * Move devices that emit radio waves or could cause radio interference away from your work area (Examples: cell phones, radios, wireless routers, microwaves)

To determine if your environment is shortening your operating range, try using your device in a different environment to see if the distance improves. If it does, look for other possible sources of interference you can remove from your work area.

My mouse or keyboard wakes the computer even when it is set not to

Symptom

After disabling the ability to wake-up the system in Windows Device Manager, the mouse or keyboard still brings the system out of sleep mode.

Solution

Even if you bought a mouse-only or keyboard-only product, the receiver that came with it still enumerates for both the mouse and keyboard interfaces.

Example

If you have two mice attached, then you would need to uncheck the “Allow this device to wake the computer” option for both mice plus a keyboard in the Windows Device Manager.

Use the process below to identify and configure the devices to not wake up the system in Windows Device Manager.

Changing wake-up settings in the Device Manager

To change the wake-up settings in Windows Device Manager, you’ll need to launch it through Computer Management and then make your selections. Here’s how:

1. Click Start, right-click Computer, and then click Manage.

2. Click Device Manager in the navigation pane on the left.

3. Select and expand either the “Keyboards” or “Mice and other pointing devices” category.

4. Right-click on the first entry and go to Properties > Details tab > Hardware IDs under the Property section.

5. Make sure the Value section contains: HID\VID_046D&PID_C52B. If it doesn’t, click Cancel and open the next mouse or keyboard entry in the list.

6. Select the “Power Management” tab and uncheck the “Allow this device to wake the computer” check box.

7. Repeat the same steps for all entries in both the “Keyboards” and “Mice and other pointing devices” categories.

Num Lock disabled after Windows 10 starts

By default, the Num Lock on your keyboard is disabled each time Windows 10 boots up after a shutdown or restart.

To configure your operating system so that Num Lock stays on during startup, please contact professional support for your operating system. This requires advanced changes that need to be done under the guidance of a professional technician.
