With the Logitech SetPoint software can be key functions and some settings (mouse movement, mouse settings for games, MicroGear Precision scroll wheel) make or stand ändern.Auch the battery can be checked by the software and you get a message if the battery is low.
The mouse is powered by a AA battery with the included USB cable, you can charge the battery. The mouse can also recharge while the AA battery without any problems benutzen.Der is included. One could use the mouse with a normal AA battery or replace the AA battery pack with a stronger one. I have the mouse for about a month and had been 3 times to unload.
