Small north pole speaker is connected to a toothbrush handle. Unit has a long cable ending with a banana plug. Push the banana plug into the Positive (red) output of the Dual Frequency Zapper set to 1 kHz and you're ready to go.
If heated or dropped, magnets can change polarity. Check the Mini North Pole Speaker on your Toothbrush Zappicator before each use by holding a compass (included for your convenience) in front of the speaker's face. If the speaker's face attracts North (N) on the compass, it is a North Pole Speaker. All units sold separately.
