What should I do if the presenter does not work?
Make sure that the polarity of the batteries is correct. The
Positive (+) and Negative (-) ends of each battery must match
the Positive (+) and Negative (-) connections in the battery
housing.
Check to see if the receiver’s USB connector is firmly
attached to the USB port on your computer.
