Wireless device does not work or is not recognized

When your device isn't working, the problem is likely a connection or power issue. This can be

due to several reasons, such as:

 Low battery levels

 Plugging the receiver into a USB hub or other unsupported device such as a

 KVM switch

NOTE: Your receiver must be plugged directly into your computer.

 Using your wireless keyboard on metal surfaces

 Radio frequency (RF) interference from other sources, such as wireless speakers, cell

phone, and so on

 Windows USB port power settings

If your keyboard is not working or frequently loses connection try the following steps:

1. Check the batteries or make sure your device is charged.

2. Make sure the keyboard is On.

3. Keep other electrical wireless devices away from the USB receiver to avoid interferences.

4. Move the keyboard closer to the USB receiver.

5. Unpair/repair or disconnect/reconnect hardware:

o If you have a Unifying receiver, identified by this logo, see Unpair a mouse

or keyboard from the Unifying receiver for instructions.

o If your receiver is non-Unifying, it cannot be unpaired. However, if you have a

replacement receiver, you can use the Connection Utility software to perform the

pairing.
