I just received a Pro0160. I am trying to unlock banks 1 and 3. I can program the banks, but cannot unlock them for scanning. I have read the manual and tried the procedure to unlock banks on page 33 Turning Banks On or Off but I cannot seem to get it to work. The Select Bank screen shows black in all the boxes. Been trying every thing except resetting the entire scanner. Looking for help. Firmware is V1,20. Thanks in advance. Andy
