REWIRING THE MICROPHONE'S DIN PLUG

The following chart shows the function of the pins in the microphone
cord's DIN plug.  This information is provided in case you need to rewire
the plug to be compatible with CB brands other than RadioShack, or with
various business band, ham, and broadcast transceivers and PA equipment.

            cannot obtain a refund or exchange on this product.
            RadioShack will provide warranty service if you cut a wire and
            find the product is defective.

          device to your local RadioShack store for service.  Only an
          accurate circuit analysis can ensure proper compatibility
          between the microphone and the device to which you connect it.
