In the event your Logitech device needs cleaning we have some recommendations:

Before You Clean
– If your device is cabled, please unplug your device from your computer first.
– If your device has user-replaceable batteries, please remove the batteries.
Be sure to switch off your device and then wait 5-10 seconds before starting to clean.
– Don’t put cleaning liquids directly on your device.
– For devices that are not waterproof, please keep moisture to a minimum and avoid any liquid dripping or seeping into the device
– 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.

Cleaning Keyboards
– To clean the keys, use regular tap water to lightly moisten a soft, lint-free cloth and gently wipe down the keys.
– Use compressed air to remove any loose debris and dust between the keys. If you do not have compressed air available, you could also use cold-air from a hair-dryer.
– You can also use fragrance-free disinfecting wipes, fragrance-free anti-bacterial wet wipes, makeup removing tissue, or alcohol swabs containing less than 25% concentration of alcohol.
– Don’t use bleach, acetone/nail polish remover, strong solvents, or abrasives.

Cleaning Mice or Presentation Devices
– Use tap water to lightly moisten a soft, lint-free cloth and gently wipe down the device.
– Use lens cleaner to lightly moisten a soft, lint-free cloth and gently wipe down your device.
– You can also use fragrance-free disinfecting wipes, fragrance-free anti-bacterial wet wipes, makeup removing tissue, or alcohol swabs containing less than 25% concentration of alcohol.
– Don’t use bleach, acetone/nail polish remover, strong solvents, or abrasives.

Cleaning Headsets
– Plastic parts (headband, mic boom, etc.): it is recommended to use fragrance-free disinfecting wipes, fragrance-free anti-bacterial wet wipes, makeup-removing tissue, or alcohol swabs containing less than 25% concentration of alcohol.
– Leatherette earpads: it is recommended to use fragrance-free disinfecting wipes, fragrance-free anti-bacterial wet wipes, or make-up removal tissue. Alcohol wipes can be used on a limited basis.

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.

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:

NOTE:  Although a device may be supported by the Unifying receiver, SetPoint and/or Logitech Control Center (LCC) software support depends on the specific product.

+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.

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

Solution
Even if you bought a mouse-only or keyboard-only product, the Unifying 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 Unifying 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.

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.
