If you have one of the old style transponders, reversing the polarity will switch it off.

Putting it back on a charge cycle will switch it back on.

For obvious reasons the charging cradle won't allow you to put it in in reversed polarity mode, so you have to have a 12V battery and a couple of bits of wire.(though I am told a 9V PP3 will also do the trick and doesn't need any extra wires)

You just hold it on the charging contacts until the lights go out and do it the other way and the lights will come back on, thus preserving the charge between one meeting and the next.

I have done it once or twice and it seems to work, but whether it does any harm is another question. You also need to mark the pins so you know what you are doing.

It just seems a bit of extra bother, you still have to remember to check the charge before using the transponder...early enough to put it back on charge if it's low....and inevitably you find that it's flat when you thought it still had a charge just before the first heat.
