What to do if my Radio Shack Pro-164 is not working?

If your Radio Shack Scanner isn't working, ensure the AC or DC adapter is properly connected to the PWR DC 9V jack, making sure the center tip is positive. Also, check the batteries; they may need recharging or replacing. If using a DC adapter and the scanner still doesn't work, unplug the adapter and clean the DC adapter socket, or check the adapter’s internal fuse.
