Drcpwen Posted June 28, 2020 Share Posted June 28, 2020 I purchased a used DN276e. After startup it reads "Set Model Number" then says "CTRL". I haven't loaded it with product but I suspect it will not work. Can you give me some advice? Link to comment Share on other sites More sharing options...
lacanteen Posted June 28, 2020 Share Posted June 28, 2020 Your battery has likely gone bad. Start there and replace it. Then on power up, push button 1 to scroll through model numbers. You want 276-7. Lock it in by pressing button 2. Link to comment Share on other sites More sharing options...
