- Place the receiver base on a stable, flat surface. Ensure it is within the desired operating range (up to 165 feet) of where the transmitter will be used.
- Connect the USB cable to the receiver's Micro USB port and plug the other end into a DC 5V USB power source (e.g., a USB wall adapter, computer USB port).
- Extend the dual antennas on the receiver for optimal signal reception.
- Press the POWER button on the receiver to turn it on. The digital LCD display will illuminate.
2. Transmitter and Microphone Setup
- Open the battery compartment of the belt-pack transmitter and insert the two 'AA' batteries, observing correct polarity. Close the compartment securely.
- Choose your preferred microphone:
- For the Headset Microphone: Plug the 3.5mm connector into the input jack on the belt-pack transmitter. Position the headset comfortably on your head with the microphone near your mouth.
- For the Lavalier Microphone: Plug the 3.5mm connector into the input jack on the belt-pack transmitter. Clip the lavalier microphone to your clothing, approximately 6-8 inches from your mouth.
- Turn on the belt-pack transmitter using its power switch. The display on the transmitter should illuminate.

The receiver offers two output options:
- 1/4'' Unbalanced Audio Output Jack: Use a standard 1/4'' audio cable to connect the receiver to the input of a PA system, amplifier, mixer, or karaoke machine.
- XLR (3-pin) Balanced Audio Input Connector: For professional audio setups, use an XLR cable to connect the receiver to an XLR input on a mixer or audio interface.
Ensure the volume on your connected audio system is initially set to a low level before proceeding.
Operating Instructions
1. Power On
After completing the setup, ensure both the receiver and the belt-pack transmitter are powered on. The LCD displays on both units should be active.
2. Frequency Selection
The system features a selectable UHF frequency design. The receiver's LCD will display the current operating frequency. If you experience interference, you can change the frequency on the receiver. Refer to the receiver's controls for specific frequency adjustment buttons (usually labeled 'CH' or with arrow icons). Ensure the transmitter automatically syncs or is manually set to the same frequency as the receiver.
3. Volume Adjustment
The receiver has an adjustable volume knob. Start with the volume at a low setting and gradually increase it to a comfortable listening level. Adjust the volume on your connected audio system as needed. Avoid setting the volume too high to prevent feedback or distortion.
4. Monitoring Signal Indicators
The receiver's digital LCD display includes AF (Audio Frequency) and RF (Radio Frequency) signal indicators.
- RF Indicator: Shows the strength of the wireless signal from the transmitter. A strong, stable RF signal is crucial for clear audio.
- AF Indicator: Shows the presence and level of the audio signal being received from the microphone.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the receiver and transmitter. Do not use liquid cleaners or solvents.
- Battery Replacement: Replace the 'AA' batteries in the belt-pack transmitter when the low battery indicator appears or when audio quality degrades. Always use fresh batteries.
- Storage: When not in use for extended periods, remove batteries from the transmitter and store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid sharp bends or kinks in the microphone and USB cables to prevent damage.
