I'm considering getting a new HP-2, since my old RS Pro 197 is now obsolete, I had just a few questions that hopefully someone can answer. First, I am not a computer savvy person. Downloading from the computer to a scanner is beyond my capability. (1) can the HP-2 be realistically programmed for an area, out of the box by simply entering the zip code ?, or does Scanner Master need to program the counties ? (2) If a firmware, or any type of update is needed, would I be notified ? & would I need to send it somewhere ? (3) I know it operates on batteries, but is there someway it can be operated by normal electricity ? ( plugging into an outlet ) (3) generally, has anyone encountered any problems or experiences with it. Any feedback or advice is welcome. Thanks, Blaster.
