Move your Bluetooth device closer to your tablet while pairing. The maximum range is 30 feet (10 meters). However, this distance may be reduced if the signal has to pass through walls or other obstructions.
Make sure that you have turned on Bluetooth on both your tablet and Bluetooth device.
Make sure that you are selecting the correct Bluetooth device from the list of available devices.
Make sure that your Bluetooth device is not paired to any other devices.
If you have connected to the Bluetooth device before but it will not re-pair, touch Remove device, then Yes to confirm. Re-pair your Bluetooth device after your tablet has finished removing it.
