- Power Connection: Connect the power adapter to the DC 12V input on the receiver's rear panel, then plug the adapter into a standard electrical outlet. Do not power on the unit yet.
- Audio Output Connection:
- For individual microphone outputs, connect XLR cables from the BALANCED-A, B, C, D ports on the receiver to your mixer or amplifier's XLR inputs.
- For a combined output, connect a 1/4" (6.35mm) cable from the MIX OUT port on the receiver to your mixer or amplifier's 1/4" input.
- Microphone Battery Installation: Unscrew the bottom cap of each handheld microphone. Insert two AA batteries into each microphone, ensuring correct polarity (+/-). Screw the cap back on securely.

Operating Instructions
- Power On the Receiver: Press the POWER button on the front panel of the receiver unit. The power indicator light will illuminate.
- Power On Microphones: Slide the power switch on each handheld microphone to the "ON" position. The microphone's indicator light will turn on, and after a brief moment (approximately 2 seconds), it will establish a connection with the receiver.

- Adjust Volume: Use the individual volume control knobs (labeled 1, 2, 3, 4) on the receiver's front panel to adjust the output level for each corresponding microphone. Start with the volume low and gradually increase it to a comfortable listening level.
- Microphone Usage: Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup. The system utilizes a cardioid dynamic microphone core, designed to pick up sound primarily from the front, reducing feedback and background noise.

- Mute Function: To temporarily silence a microphone without turning it off, slide the microphone's power switch to the "MUTE" position. Slide it back to "ON" to resume audio.
- Wireless Range: The system offers a long transmission range of up to 260 feet (approximately 80 meters) in open, unobstructed spaces. Performance may vary depending on environmental factors and obstacles.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and microphones. For stubborn dirt, a slightly damp cloth can be used, but ensure no liquid enters the devices. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace microphone batteries when the battery indicator light dims or the audio quality degrades. Always use fresh AA batteries and dispose of old batteries responsibly.
- Storage: When not in use for extended periods, remove batteries from the microphones to prevent leakage. Store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
