Now, My onw box went bad. The yellow light on ch 3 doesn’t stop flashing. Is it any electrical discharge that I have to do, or a discharge into a garbage can that is waiting for that unit? It took me a long time to get it working, I could only make few calls, when I turn it off and on, the ch 3 light does not go on. I;m just tired of this box. If anyone knows how to fix it, please, e-mail at email@example.com. I greatly appreciate. Luis.
