You are doing a great job with the manual!!
btw: I am afraid this is a little bit off-topic: I saw your warning on the power supply plug polarity. Wouldn't it be a good idea, to place a Schottky diode into the rig itself? Ever since I lent one piece of relatively expensive equipment that returned to me burnt beyond repair, I am always making supply cables with such protection. This is until some 'clever' guy will try to use his own wrongly wired cable. So the protection in the box itself will make better sense.
Now in this 'prerelease' period dangers are perhaps low, but as less routined hams will come that will change, I'm afraid ...
