Recently purchased TEC "Chat-Trapper" inline Telephone Recording Jack Adapter (Manufactured by Lynn Electronics Corp., Ivyland, PA) for use in combination with Sony ICD-PX 820 Voice Recorder. First time I hooked everything up it worked like a charm, clear crisp sound quality. Bodda boom, boda bing! However, after the passage of a few hours time, everything came to a screeching halt. The voice recorder's speaker stopped working even after I disconnected it from the adapter. Took me two hours to get the sound back (no idea, just kept fiddling with it til the sound starting working). Went to store and swapped the recorder for a new one. Came home, plugged evrything up, worked beautifully. Next morning, nothing but static. Am using an Emerson Slimline Caller ID Phone (Model No. EM2517, keypad in handset). Is it possible that I should not be leaving the recorder plugged into the adapter when the phone rings, or even not at all unless actually using it to record?
