I recently purchased a Prairie Blaster. The first time I took it out it operated correctly for about 30 seconds then made a very loud hornlike sound and went quiet. After that I had to power the unit down before it would make another sound. After testing the unit I have discovered that if I take the volume to 28 or higher it quits the sound requested and makes the loud horn/buzz sound. Does anyone have any suggestions or know if this is a common problem and how do I fix it?
