It looks promising. I get a cursor by pressing the small FMS knob, then both the large and small knobs scroll up/down the list of LRUs. See the second photo in my previous post: a plus sign next to a label means you can expand it to view subtopics, a minus sign means the subtopics are already displayed, indented, below the LRU label.
Once the cursor highlights, for instance, GMA1, then I can push ENT to get a list of sub-topics. I can navigate among the subtopics using either FMS knob, interchangeably, but once I’ve got a subtopic highlighted there is no further action possible. The ENT key advances the cursor by one subtopic, just as either the small or large FMS knobs do.
Clearly I do not understand something about Configuration Mode, but I’m stuck.
The soft keys are always the same: DNLD Log, SYS Export, and ACFT RPT.
