Gemini Air Remote loses Blue-Tooth Connection

I have had one replacement of my Gemini Air Dongle and it's Remote where I experienced several failures including connecting to the Remote(Blue-Tooth or BT connection). On the replacements, after about 2 weeks I experienced lose of the BT connection(two blue lights on remote pulsing for several seconds) so I replaced the batteries with new and it has worked for a couple more weeks without incidence. Now it is starting to occasionally lose connection again. How can I better diagnose the problem?
