I use the pro-2051 as a base with an outdoor antenna. I like this unit more than I thought I would once I figured out how to program it.
To reset the unit, have the unit off, press hold, 2, and 9. Turn unit "on" with push from tongue. You will see the word CLEAr on the screen.
To reload original 150 channel banks, have the unit off. Press 3 and E and turn unit "on" with any convient toe. You will see the channels reload. Then you can enter your state code and program them in automatically.
I reset my unit, then just loaded the chennels I want to follow. I have both Motorola and Erickson trunking in my area. EDACS was hard to figure out from the manual but after trial and error, it works.
This unit has kinda relit a fire for my ham license. Ham channels are just dead unless there is a storm, then you can't get them to shut up. HF side is somewhat active at times, if there is a contest going on. Otherwise, guys talking about their antennas...
Have fun with your radios...
