To all the owners of a new MRC Prodigy Wireless Remote that starts experiencing decoder problems with their locos. It states to recharge the batteries if the charge falls below 4 volts, but that is a little premature as it will behave correctly down to about 3 volts. But it doesn't just quit working, when in low battery state, it starts sending false signals! You may be clicking F12 and it will send a F11 signal, or in some cases will send it to the wrong loco! So before you start reprogramming your decoders, check your battery charge status. It will continue to send signals until the batteries are completely depleted, but not necessarily the right ones. This little ditty is not brought out in the manual!
