Operating Instructions
Microphone Usage
- Power/Mute Switch: Each microphone has a slide switch for On/Mute/Off. Slide to "On" to activate, "Mute" to temporarily silence, and "Off" to power down.
- Battery Indicator: The microphone's display shows the current battery level. Replace batteries when the indicator is low to avoid interruptions.
- Cardioid Pickup: The microphones feature a cardioid pickup pattern, which primarily captures sound from the front, reducing background noise. For best results, speak directly into the top of the microphone.

- LCD Display: Shows current frequencies for Microphone A and B, signal strength, and battery status.
- Volume Controls (VOL.A & VOL.B): Separate rotary knobs to adjust the output volume for each microphone independently.
