[Elecraft] [P-3] Some menu items in 00.41 are not retained at power off

[kz5d at aol.com]

Hello all,

One of the menu items available in 00.41 is the ability to assign centering Marker A or B to a Function button. After selecting it in the menu, it works as it should. But whenever the rig is powered off and turned back on, the feature is disabled. I have to go back in the menu and select this again. However, if I select to use the "tap knob" feature for centering Marker A or B, that is memorized. Other menu items are memorized. 

And while I have your attention, what does "Level Calibrate" do?

Thanks for the input.
