Hey Jerry

Before we panic, give the battery a full charge and try again. As you know the transmitter needs a certain voltage, like something more than 6.9V, to be delivered to it before it can function. Anything less and it will shut down.

Now losing memory settings, that is a different thing but, in a way, it also can be related to a low battery.

So let's get this battery juiced up and topped up and let's test again. It also could be a failing battery, so that should tell us.
