Had a little scare tonight with my 2 week old HP-2. Was monitoring for a few hours......noticed no audio,looked over and the scanner had went completely dead. Looked closer and the display had real dark squiggly lines. Immediately removed the batteries and reseated the sd card......turned back on and it's been fine since then. I had previously tried doing the database update.....still 04/05 only available,so not sure if that had anything to do with things or not. Any thoughts? Thanks in advance.
