Note: These instructions also apply to some Dell cordless keyboards and mice that are sourced from Logitech. (They will be so marked.)
1) The Logitech Cordless Mouse & Cordless Optical Mouse both use AAA size batteries (1.5 volts). [This is subject to change without notice.]
2) The Logitech Cordless Keyboard uses two AA size (penlight) batteries (also 1.5 volts). [This is subject to change without notice.]
3) Be careful when inserting the batteries that you put them in correctly. It is very easy to put them in so that the positive (+) end of the battery is in the negative side ( - ) or vice versa.
4) Be sure to check the batteries periodically with a Battery Checker. You can buy an inexpensive Battery Checker at Radio Shack or at some computer stores that tells you whether the battery is OK or if its time to Replace them. Check the batteries before you put them in to be sure you arent putting in old batteries if they are not coming straight from the box.
5) The batteries normally last about 4 to 6 months with the Logitech Cordless Mouse, and about 2 months with the Logitech Cordless Optical Mouse (the one with the red laser in it and no ball). You should see a window pop up on the screen pop with a warning when the batteries are low.
1) Push the Connect button on the Receiver (that box that looks like a dark gray pack of cigarettes located on the right side of the monitor).
2) Press the Connect button on the underside of the mouse.
3) Likewise, turn the keyboard over and press the Connect button on the underside of the keyboard.
Note: Some Logitech keyboards have the Connect button on the right side.
4) You will then see a small window pop up in the center of your screen indicating that you are attempting to connect the cordless devices together.
5) Click on the Close or Cancel button to get rid of the small window.
1) Keep the distance between the Receiver and the Mouse at about 8 to 12 inches. (The maximum distance they can be separated is about 6 feet, but the mouse will usually work better at 8 to 12 inches.)
2) Keep the distance between the Receiver and the Keyboard at about 8 to 12 inches, too.
