Thank you, but I am extremely dyslexic and have difficulty reading technical manuals. For some reason, the architecture of my GRE PSR 500 was much easier to understand. Hence, I could understand the "Easier to Read" manual for the PSR 500 because I could understand how to program it.
I bought my 436HP in 2002. I learned to use the aforementioned keys after someone described to me in terms I could understand, during 2021.
What I am going to do now, which is how I generally learn, is play around with it and see how it downloads in my profiles, etc. I wish this radio allowed me to review what was on each start up key. I thought I saw this once when I moved the cursor over the various system Quick Keys.
