Two things going on with this old scanner.
Previously perfectly functioning then out of the nowhere the unit starting displaying "Fr Err" on all frequencies. The unit will not scan or search, again just display "Fr Err". Clearing the stored frequencies and reprogramming them nets the same result. Also, scanner audio is muted both from the internal speaker and the headphone jack. Changing the batteries or switching to AC power doesn't help.
