A power microphone is used to increase the modulation output of a CB radio because it has a amplification circuit that makes your voice sound louder. However, if you are constantly using your CB radio microphone and you realize that the battery inside it is dead or showing signs that it is dying, signs such as the power light dims, or low voice modulation, when you key the mic, you will need to replace the battery inside it.
Instructions:
1)There will be a screw on the back of the power microphone, that holds the rear plastic cover in place, so using your hands, unscrew the screw. Once you have unscrewed it, place it in a location that it can't get lost because if you misplace it, the plastic cover will fall off.
2)Remove the rear plastic cover and remove the 9 volt battery from the battery snap.
3)Recycle the dead battery and remove the new 9 volt battery from the packaging, then insert it onto the battery snap.
4)Once the battery is connected onto the battery snap, place the battery inside the power microphone, then replace the rear plastic cover you removed earlier.
5)Then replace the screw back into the hole and screw it tight.
