Logitech Wireless Combo MK520

Battery management

Your keyboard has up to three years of battery life and your mouse has up to 18 months.*
Battery sleep mode
Did you know that your keyboard and mouse go into sleep mode after you stop using them for a
few minutes? This feature helps limit battery usage and eliminates the need to keep switching your
devices on and off. Both your keyboard and mouse are up and running immediately once you begin
using them again.
How to check the battery level for the keyboard
Press and hold the FN key, then press the F12 key: If the LED
glows green, the batteries are good. If the LED glows red, the
battery level has dropped to 10% and you have only a few days
of battery power left. You can also turn the keyboard off then
back on using the On/Off switch on top of the keyboard.
How to check the battery level for the mouse
Turn the mouse off then back on using the On/Off switch on the mouse
bottom. If the LED on top of the mouse glows green for 10 seconds, the
batteries are good. If the LED blinks red, the battery level has dropped to
10% and you have only a few days of battery power left.
* Battery life varies with usage and computing conditions. Heavy usage usually results in shorter battery life.
