When you receive this microphone the battery wire is outside the microphone case. This is just to demonstrate that the mic needs a battery. The microphone should not be used with a battery attached outside the case. The battery wires are routed by the push to talk button inside the mic. They should be rerouted away from the button prior to use to avoid damage to the wires.
