In ideal situations, the K340 can operate up to 30 feet (10 meters) with the receiver in clear sight of the keyboard.
If you are not getting this distance:
- Replace the batteries with a fresh set.
- Use the USB Receiver stand (included with your K340) to move the USB receiver to a line of sight or change its positioning.
- Move devices such as cell phones, radios, wireless routers, microwaves, and other devices that emit radio waves or could cause radio interference (RF) away from your work area.
To determine if your environment is causing shorter than expected ranges, try using your K340 in a different environment to see if the distance improves.
