Using the dip switch on a dab radio will allow you to adjust its settings. Here are the steps. The first thing to do is to look for the small switch on the back of the radio. Dip switches are used for this function. After you have the switch opened, use a small object, such as a pen or paperclip, to flip it. Depending on what you want to accomplish, the switch has to be turned up or down. The switch needs to be flipped up to turn on the radio. It is necessary to flip the switch downward to turn off the radio. In addition, the dip switch can also be used to change the radio's volume. You can increase or decrease the volume by flipping the switch up or down, based on your preference.
