I have been using EasyTek with my Pure Binax instruments with reasonable success. Recently, I asked Sygna how to pair the Easytek with my Tek transmitter. Their instructions did not work and as a result, they recommended resetting the instruments, Easytek and Tek transmitter. The result is that Easy Tek will no longer pair with my Pure BINAX, the green light flashes continuously and Signa says it will not pair while green light flashes. They offer no more help. I am sure there is a software solution to this, but I am not near a knowledgeable dealer. Can someone help?
