This is a stupid question but has anyone else had a problem with MTH's DCS suddenly not working? I immediately put new batteries in it but it still says things like 'OUT OF RANGE', 'OUT OF RF RANGE', 'CHECK ENGINE', MAINTENANCE NEEDED' or ENGINE NOT ON TRACK'. I'm holding the hand held (with new batteries) right next to the TIU and the engine is right there no more than several inches away. Sometimes the frustration brought on by these modern locos is enough to make one run screaming back to the old postwar and MPC because they ran. No surprise issues when you least expect it.
Is the issue with my hand held unit? or the TIU? Neither one has been dropped or stored in a hot (or cold) place and they have been functioning very well until now? They randomly do this now with a few of my other MTH engines, I just checked. Any suggestions?
