I don't have the manual but I'm fairly sure this is normal and the E symbol just means that it's getting an echo.

That is correct - so you know it is the (E)cho sounder and it is functioning correctly. Manual here

I had exactly the same problem. Which idiot at Nasa decided that an "E" on the display would be a comforting indication that as was well ? Took me ages ( i.e. until I read the effing manual ) to find out that it meant all was well. /forums/images/graemlins/blush.gif
