Battery management

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.

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.
