Some of the readout boxes (2 and 4, I think) are hard coded into the chart views...
You can actually change the selection for those hard coded readout boxes in the menu system...but the change you wanted in those boxes will not activate when you look at the box on the chart view...
I'm guessing HB has decided that anytime a user is operating the chart view...that user needs to see that hard coded info in those 2 boxes...
All the Readout box info in the other views (without a chart view showing)...can be changed to any selection...
Some boxes can have the info shut off and leave a white box...in some views other than chart..
Some boxes can be opaqued...in some views other than chart...
Some boxes can be eliminated completely...in some views other than chart...(in select series units)...
All 5 readout boxes can be eliminated in the Full Screen SI View only (of the 800 and 900 series units under the Sonar tab)...
