Setup
- Receiver Placement: Position the receiver unit in a central location, away from large metal objects or other wireless devices that may cause interference. Ensure the antennas are fully extended and positioned vertically for optimal signal reception.
- Power Connection: Connect the provided power adapter to the receiver's DC input and plug it into a power outlet.
- Audio Output Connection:
- For individual channel output: Use XLR cables (not included) to connect the balanced XLR outputs (CH A, CH B, CH C, CH D) on the receiver's rear panel to your mixer or amplifier.
- For mixed output: Use the provided 6.35mm audio cable to connect the MIX OUT jack on the receiver's rear panel to your mixer or amplifier's input.
- Transmitter Battery Installation: Open the battery compartment on each bodypack transmitter. Insert two AA batteries, ensuring correct polarity. Close the compartment securely.
- Microphone Connection: Connect the desired lavalier or headset microphone to the 3.5mm input jack on each bodypack transmitter.

Operation
- Power On: Turn on the receiver unit using the power button. Then, turn on each bodypack transmitter.
- Automatic Frequency Sweeping (Initial Setup): With the receiver on, turn on a bodypack transmitter. It will automatically sweep for an available frequency and pair with the receiver. No manual frequency comparison is needed for initial setup.
- Changing Frequencies: Each channel has 30 available frequency points. To change the frequency for a specific bodypack transmitter, press the 'Channel' button (frequency change key) on the transmitter. The transmitter will then automatically sweep and select a new frequency point, which will be automatically matched with the receiver.
- Switching Channels (A/B and C/D): To switch between channel A or B, or channel C or D, press and hold the frequency switch on the bodypack transmitter for approximately 8 seconds. This allows you to assign a transmitter to a different channel group.
- Using Multiple Sets of Machines:
- First, power on one receiver.
- Press the frequency change key on a bodypack transmitter.
- Then, press and hold the power button on the bodypack transmitter for about 8 seconds, pointing it towards the receiver antenna.
- The receiver's display will show a 'lock' indicator, confirming successful pairing. This indicates that the reception of one channel is locked, and other transmissions cannot enter the same frequency point. Repeat this process for all channels.
- After locking all channels on the first receiver, turn off both the receiver and all paired transmitters.
- You can then set up another system following the same procedure. Note that multiple sets of machines can be used simultaneously, but they must operate on different frequency points to avoid interference. If interference occurs, you can change the frequency of the affected bodypack transmitter after unlocking it.
- Adjusting Volume: Use the individual volume knobs on the receiver unit to adjust the output level for each microphone channel.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the receiver and transmitters. Avoid using liquid cleaners or solvents, as they may damage the finish or internal components.
- Battery Replacement: Replace batteries in the bodypack transmitters when the low battery indicator appears on the receiver's display or the transmitter's screen. Always use fresh AA batteries. Remove batteries if the system will not be used for an extended period to prevent leakage.
- Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid sharp bends or kinks in cables. Store cables neatly to prevent damage.
