GGG posted:Model numbers help, Are these PS-1 or PS-2. If you look at your manual there are instructions for a conventional reset. For PS-2, one Whistle and 5 Bells in rapid succession.
Other issue can be a bad speaker, especially for PS-2 5V.
Other issue can be corroded terminal for battery, based on old battery left in too long and gassing out.
So both can be simple fixes. G
GGG, thanks for your response. As indicated they're both PS-2. The SW-1 has the 3V, and is item #30-2742-1. The doodlebug has the 9V, and is #30-2190-1. Each has the appropriate version of the BCR installed.
Alas, I'm all too familiar with the "reset to defaults" sequence. Neither unit seems very impressed when I apply it, although the doodlebug does give me the two toots that says it heard me.
Gives me the two toots, but doesn't seem to give two hoots, in other words....
