3. Setup Instructions
- Receiver Placement: Place the wireless receiver on a stable, flat surface, away from potential sources of interference such as large metal objects, digital devices, or other wireless equipment. Ensure the antennas are fully extended and positioned vertically for optimal signal reception.
- Power Connection: Connect the provided power cord to the receiver's power input and then to a suitable power outlet. Press the power button on the receiver to turn it on. The display should illuminate.
- Microphone Battery Installation: Unscrew the bottom part of each handheld microphone. Insert two AA batteries (not included) into each microphone, ensuring correct polarity (+/-). Screw the bottom part back on securely.
- Audio Output Connection:
- Unbalanced Output: Use the provided 6.35mm audio cable to connect the receiver's 6.35mm MIX OUT port to the audio input of your mixer, amplifier, active speaker, or computer.
- Balanced Output: For professional setups, use XLR to XLR audio cables (not included) to connect the receiver's BALANCED XLR OUTPUTS (A and B) to the corresponding balanced inputs on your mixer. This provides independent control over each microphone channel.
- Antenna Installation: Screw the two antennas onto the corresponding connectors on the rear panel of the receiver.

4. Operating Instructions
- Powering On Microphones: Press and hold the power button on each handheld microphone until its display illuminates.
- Automatic Frequency Scan (Auto Scan):
- On the receiver, press the 'SCAN' button. The system will automatically scan for available, interference-free frequencies.
- Once a frequency is found, the receiver's display will show the selected frequency.
- Synchronizing Microphones (SYNC):
- After the receiver has found a frequency, align the infrared (IR) window of the microphone with the IR sensor on the receiver (usually labeled 'IR' or 'SYNC').
- Press the 'SYNC' button on the receiver. The receiver will transmit the selected frequency to the microphone. The microphone's display should update to match the receiver's frequency.
- Repeat this process for the second microphone, ensuring each microphone is synchronized to a different channel (A or B) on the receiver.
- Volume Adjustment: Use the volume control knobs on the receiver (usually labeled 'VOL A' and 'VOL B') to adjust the output level of each microphone independently. Adjust the volume on your connected audio device (mixer, amplifier) as needed.
- Frequency Selection (Manual): If automatic scanning is not desired or if you need to manually select a frequency, use the 'UP' and 'DOWN' buttons on the receiver to cycle through available frequencies for each channel. Remember to re-sync the microphone after changing frequencies manually.
- Monitoring Display: The receiver and microphone displays show important information such as frequency, channel, and battery status. The receiver also features a 7-color gradient display for visual feedback.

5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the receiver and microphones. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
- Battery Care: Remove batteries from the microphones if they will not be used for an extended period to prevent leakage and damage. Dispose of used batteries responsibly.
- Storage: Store the system in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. Keep the original packaging for safe storage and transport.
- Antenna Care: Handle the receiver antennas with care to avoid bending or breaking.
