+Cleaning Logitech keyboards and mice
Before you clean your device:
Unplug it from your computer and make sure it’s turned off.
Remove the batteries.
Keep liquids away from your device, and don’t use solvents or abrasives.
To clean your Touchpad, and other touch-sensitive and gesture-capable devices:
Use lens cleaner to lightly moisten a soft, lint-free cloth and gently wipe down your
device.
To clean your keyboard:
Use compressed air to remove any loose debris and dust between the keys. To clean the
keys, use water to lightly moisten a soft, lint-free cloth and gently wipe down the keys.
To clean your mouse:
Use water to lightly moisten a soft, lint-free cloth and gently wipe down the mouse.
NOTE: In most cases, you can use isopropyl alcohol (rubbing alcohol) and anti-bacterial wipes.
Before using rubbing alcohol or wipes, we suggest you test it first in an inconspicuous area to
make sure it doesn’t cause discoloration or remove the lettering from the keys.
+Comfort Guidelines - Important Ergonomic Information
Whether you spend five minutes or five hours using your keyboard, mouse or trackball, these
suggestions can help you stay comfortable and productive. Some research suggests that
long periods of repetitive motion,
using an improperly set up work space,
incorrect body position, and
poor work habits
may be associated with physical discomfort and injury to nerves, tendons, and muscles. If you
feel pain, numbness, tingling, weakness, swelling, burning, cramping, or stiffness in your hands,
wrists, arms, shoulder, neck, or back, see a qualified health professional.
Follow the guidelines in the guidelines PDF file below to maximize your comfort and lessen the
chance of injury.

The guidelines are written in the following languages: English, Deutsch, Francais, Italiano,
Espanol, Portugues, Nederlands, Svenska, Dansk, Norsk, Suomi, Greek, Russian, Hungarian,
Czech and Polish.

+Backup device settings to the cloud in Logitech Options
INTRODUCTION
HOW IT WORKS
WHAT SETTINGS GET BACKED UP
CURRENT LIMITATIONS
INTRODUCTION
This feature on Logi Options allows you to backup the settings of your Options supported device
automatically to the cloud after creating an account. If you are planning to use your device on a
new computer or wish to go back to your old settings on the same computer, log into your
Options account on that computer and fetch the settings you want from a backup to setup your
device and get going.
HOW IT WORKS
When you are logged into Logitech Options with a verified account, your device settings are
automatically backed up to our cloud by default. You can manage the settings and the backups
from the Backups tab under More settings of your device (as shown in the screenshots below):
Manage settings and backups by clicking on More>Backups.
AUTOMATIC BACKUP OF SETTINGS - If the ‘Automatically create backups of
settings for all devices’ checkbox is enabled, any settings you have or modify for all of
your devices on that computer are backed up to the cloud automatically. The checkbox is
enabled by default. You can disable it if you don’t want the settings for your devices to
be backed up automatically.
‘CREATE A BACKUP NOW’ button - This button allows you to backup your current
device settings yourself, if you need to fetch them later.
‘RESTORE SETTINGS FROM BACKUP’ button - This button lets you view and
restore all the available backups you have for that device that are compatible with that
computer, as shown above.
The settings for a device are backed up for every computer that you have your device connected
to and have Logitech Options that you are logged into. Every time you make some modifications
to your device settings, they get backed up with that computer name. The backups can be
differentiated based on the following:
1. Name of the computer. (Eg. John’s Work Laptop)
2. Make and/or model of the computer. (Eg. Dell Inc., Macbook Pro (13-inch) etc.)
3. The time when the backup was made.
The desired settings can then be selected and restored accordingly.
WHAT SETTINGS GET BACKED UP
Configuration of all the buttons of your mouse
Configuration of all the keys of your keyboard
Point & Scroll settings of your mouse
Any application-specific settings of your device
WHAT SETTINGS ARE NOT BACKED UP
Flow settings
Options app settings
CURRENT LIMITATIONS
1. The device settings aren’t compatible between Windows and Mac operating systems. So,
the settings from Windows operating system cannot be applied to a computer with the
Mac operating system and vice versa.
2. There are some features that are available only on certain versions of Windows operating
system. For example, triggering Cortana through a mouse button press is a feature
available only on Windows 10 and not on Windows 7 and 8 as Cortana is not available
on those operating systems. In such cases, those features cannot be applied on the
unsupported operating systems.
