The DCS hand held remote has not been used for around two years. Tried to power up, pressing the on/off button, and nothing happened. Replaced the four batteries and tried again. Zip. Nothing shows on the screen. The MTH dealer near us is no longer from what I can tell so no help there.
Not good...outside of checking the battery polarity and making sure the batteries are snug I'm not sure what else you can do. If you're familiar with the dcs loader you could try loading the software again but that seems extreme and probably won't help. long shot.
