I recall now, about 2 years back, Dee buzzed me on the intercom thats part of our basket of wireless phones here, in a total panic, wanted fresh batteries in the remote as she was missing one of her fav game shows. On my arrival with a pocketfull of batteries, the first thing I noticed was she had set something in front of the tv's IR window. I reached over and handed it back to her & told her to try it again. Of course it worked, much to her amazement, it had never been grokked that if she couldn't see that window, she didn't have a remote. OTOH, she had cataracts removed from both eyes since, and its entirely possible she could not see that little black square in the bottom of the black face frame. She sure can now. > > > ---------------------------------------------------------------------- >-------- _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users
