FAQs
Why does my MK540 keyboard or mouse lose connection frequently?
Common causes include interference from other 2.4 GHz devices, distance exceeding 10 meters, or low batteries; try moving closer to the receiver, changing USB ports, or using the Logitech Unifying software to re-pair—ensure no metal objects block the signal.
Is the MK540 compatible with Mac, iPad, or non-Windows devices?
It is fully compatible with Windows 7 and later, as well as Chrome OS; however, it does not work with macOS, iPadOS, or smart TVs out of the box due to the USB receiver—Bluetooth alternatives like the K580 are recommended for Apple ecosystems.
What is the battery life for the keyboard and mouse, and how do I replace the batteries?
The keyboard lasts up to 36 months on two AAA batteries, while the mouse offers up to 18 months on one AA battery; both have On/Off switches to conserve power—batteries are accessible via compartments on the underside, and low battery indicators flash on the devices.
