Ok so the other day I cleaned out my storage and this ancient beast that I bought from a thrift store a couple years ago (PRO-2001). I never really used it before and when I plugged it in and started scanning i realized it was programmed with 300, 700, 800 and 900mhz freq's (Its not supposed to pick up those bands)! I tried to program in some local freq's but after i turn it off there gone and the ones above are back! I also tried to program some 300mhz frequencies and it says ERROR! Any reason why this is happening? Can this be modified and can I restore it to original?
