DRS4D would not transmit


This morning our DRS4D would not transmit, message on screen that unit was in pre-heating mode. Did not want to try and diagnose while underway, but at the end of the day shut off MFD12 and turned it back on. Everything worked again.

Any ideas? We are headed for St. Lawrence River after the weekend and want to resolve before we head downstream.
Sounds like it wasn't fully being seen by your unit or your power levels were getting low on the boat. I would recommend running the Installation Wizard (don't hit SKIP) to let everything be seen and SAVE & EXIT. When the unit comes up, go under MENU - RADAR and select your radar from the pull down under GENERAL - Radar Source. I would also recommend that you have kept your unit/radar software up to date.
