Recharging
Recharging the mouse
To charge your mouse, plug the charging
cable into a powered USB port. Recharge
your mouse when the battery indicator
blinks red.
Do not use the receiver extender cable
for recharging. Use only AA NiMH
replacement batteries
(1800 mAh minimum).
Recharging the keyboard
Typically, you can expect about 10 days
of battery life before you will need to
recharge the keyboard battery.* If the
backlighting level is set to 100%, you have
about 15 hours of battery life.
To recharge the keyboard, connect it to
your computer using the USB recharging
cable. A full battery recharge takes about
5 hours and only 3 hours if the keyboard
has been switched o.

* Battery life varies with usage, backlighting level, and computing conditions.
Heavy usage usually results in shorter battery life.
