Hi @gemac22 ,
Just verifying, have you got the Logitech Cordless 2.4 GHz Presenter Connection Utility 1.0 software installed in your PC?
Here is a link where you can download it from if you haven't got it installed already.
These are the relevant instructions for the presenter from the Read Me file contained in the download.
''For connecting the presenter:
- Install the batteries into the presenter.
- Turn ON the presenter.
- '''Double-click on the "LogiBindP" utility.'''
- Press the Reset button under the device.
- When done, click OK.''
