How to Troubleshoot a Johnny Stewart PM-4

The Johnny Stewart PM-4 Wireless Preymaster is a wildlife caller that allows you to set up the wireless speaker and base unit over one hundred yards from your location. The sounds are controlled by the handset, giving you access to wildlife with complete freedom and safety. Hunters use the devices to attract Deer. Hunters and ranchers also use the devices to control predator and pest populations. Birdwatchers and other nature lovers use the callers for their own enjoyment. No electronic device is without a few gremlins, and there may be times when you will need to troubleshoot the PM-4 to get things back in working order.

      Check to make sure that the sound cards are in the controller. If there is no sound, it could be due to the lack of a sound card. It's recommended that you remove the sound cards when storing the unit, and it can be easy to forget to re-install them when using the unit again.

      Clean the sound cards if the sound is distorted. Spray contact cleaner onto the contact pins of the card. The pins on the card are delicate and can easily become dirty, especially if they are not stored properly.
