Moving the scanner from one room to the next while scanner was on, heard it beep. I pushed a button, then the unit displayed "hold" yet it was scanning in just the group that was displaying hold. Now the result was handy because it weas scanning on one group, though not particularly a group of interest. I tried pressing the scan key, unit still just scanned the group I was in, and the group was indicating hold. Only way I could get back was reloading, and then I had to delete all, then reload. Question, what happened, and there has to be a better way of getting back to scanning all rather than 1 group scanning. should say it was scanning on one system, and stuck, could not get it out of 1 system that was scanning.
