A screen appears with "Menu" in the upper right corner; touch Menu, then Display Check, then Vehicle Signal Check, which will bring up a screen showing, among other things, the aux. battery voltage, which in Ready mode will be ~13.8V (the charging voltage delivered by the big battery). Turn ignition key back to the "on" or "access" position for aux. voltage reading when not being charged (engine off).

BTW, the display screen can be quite picky about the touches. Have fun! 8-)
