I ordered a VP83F Mic last week, got it in the mail, read the manual, put in the batteries, pressed power and it did not turn on. I tried for hours to figure out what was wrong, tried new batteries, had other people try, nothing. Why won't this thing turn on? I've run out of ideas.
We have seen this problem if the batteries are not installed with the correct orientation.
Also, make certain to push the LEFT button for several seconds to power up the unit. Sometimes, a user presses the button with the red dot, thinking it is the power button.
