In an ideal environment, a mouse or keyboard can operate up to 30 feet (10 meters) away from the USB receiver (shown below) in a clear line of sight.

If you're not getting this distance, try these suggestions:

• Replace the battery/batteries or make sure your mouse or keyboard is fully charged
• Move devices that emit radio waves or could cause radio interference away from your work area (Examples: cell phones, radios, wireless routers, microwaves)

To determine if your environment is shortening your operating range, try using your device in a different environment to see if the distance improves. If it does, look for other possible sources of interference you can remove from your work area.
