Input:
Defective unit, scan function worked 1 out of 30. Battery trays are very poorly made. The eight battery compartment would not power the unit. If the unit was working as designed I would have great concern for the longevity of the battery holders. As they were not straight in the compartments with slight alignment issues. Audio was acceptable and it did bring in the NOAA clearly.
