Just an FYI, having used the TA-312s a lot, you do not need the batteries, they just make it work better. With out them you still get a signal (just weaker), and it will still ring (just quieter). with out the batteries they are a it worse then the TA-1 (also used it a lot), but we used them lots with out the batteries. I believe that where it becomes a issue is when used over very long distances. I have never used them over more than a single spool of wire or two at the most (1/2 mile or less). I have never used the TA-43n so not sure if it is the same or not.
