If your mouse is not appearing in your devices Bluetooth list, please make sure when you are putting it into Bluetooth pairing mode that you move the switch on its base all the way from Off to On in one quick movement, without stopping at Presenter. As just moving from Off to Presenter will not initiate Bluetooth pairing mode.
Also be sure not to hold the front mouse button down for longer than five seconds while setting the switch to On. As after five seconds the LED will turn green and your ProPoint will instead be put into USB receiver pairing mode (This is indicated by the LED changing from orange to green).
Lastly to pair with the ProPoint over Bluetooth your computer/device will need to have at least Bluetooth 4.0 support. Most devices released after 2012 will have BT4.0 or above, but one exception to this is computers running Windows 7. As Windows 7 does not have Bluetooth 4.0 support the USB receiver will be required to connect with ProPoint.
