Troubleshooting
Keyboard and mouse not working
• Check your keyboard and mouse
are powered on.
• Check that the receiver is securely
plugged into a USB port on
your computer.
• If the receiver is plugged into
a USB hub, try plugging it directly
into your computer.
• Try plugging the receiver into a different
USB port closer to your keyboard
and mouse.
• Remove any metallic objects between
the receiver and your keyboard
and mouse.
• Check that you pulled the battery tab
out of your keyboard and mouse.
• Check the orientation of the batteries.
The mouse uses one AA alkaline
battery and the keyboard uses two AAA
alkaline batteries.
