  If your Radio Shack Scanner is totally inoperative with no power, there might be several reasons: * The batteries may have failed. Recharge the rechargeable batteries or replace the standard batteries. * The batteries may be installed improperly. Install the batteries according to the polarity markings. * The AC or DC adapter may not be connected properly. Ensure the adapter’s barrel plug is properly connected to the PWR DC 9V jack.

  There are a couple of reasons why your Radio Shack Scanner might have poor or no reception: * An antenna might not be connected or is connected incorrectly. Make sure an antenna is connected to the scanner. * Programmed frequencies might be the same as birdie frequencies. Avoid programming birdies or only select them manually.
