Setup Instructions
- Install Batteries: Each unit (transmitter and receiver) requires one AAA battery (sold separately). Open the battery compartment and insert the battery, ensuring correct polarity.
- Connect Lavalier Microphone: Plug the 3.5mm connector of the lavalier microphone into the 'MIC IN' jack on the transmitter. Secure the microphone to the speaker's clothing, approximately 6-8 inches from the mouth, for optimal sound capture.
- Connect Receiver to Recording Device: Use the supplied audio cable to connect the 'AUDIO OUT' jack on the receiver to the microphone input of your DSLR camera, camcorder, or audio recorder.
- Mount Receiver: Attach the receiver to your camera's hot shoe using the integrated camera mount.
- Select Channels: Both the transmitter and receiver have a 'Frequency Mode' switch. Select one of the four available channels (1-4) on both units. Ensure that the selected channel is identical on both the transmitter and receiver to establish a connection. If you experience interference, try switching to a different channel.
Operating Instructions
- Power On: Press and hold the power button on both the transmitter and receiver until the LED indicator illuminates. The LED will indicate battery life.
- Volume Control: Adjust the audio output level using the 'Volume Control Wheel' on the receiver. It is recommended to start with a lower volume and gradually increase it to avoid clipping or distortion.
- Real-time Monitoring: For optimal audio quality, plug headphones into the 'Headphone Jack' on the receiver to monitor the audio in real-time. This allows you to verify sound integrity and make adjustments as needed.

Maintenance
- Keep the units clean by wiping them with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Store the system in a dry, cool place away from direct sunlight and extreme temperatures.
- Remove batteries from both the transmitter and receiver if the system will not be used for an extended period to prevent battery leakage.
- Handle the antennas with care to prevent bending or breaking.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output | Units not powered on; Low/dead batteries; Incorrect channel selection; Loose cable connections; Receiver volume too low. | Ensure both units are powered on; Replace batteries; Match transmitter and receiver channels; Check all cable connections; Increase receiver volume. |
| Interference or static noise | Nearby electronic devices; Other wireless signals; Operating beyond range; Incorrect channel. | Move away from other electronic devices; Switch to a different channel; Reduce distance between transmitter and receiver; Ensure antennas are positioned correctly. |
| Low or distorted audio | Microphone too far from source; Receiver volume too high/low; Low battery on transmitter; Microphone input level on camera too high. | Adjust microphone placement; Adjust receiver volume; Replace transmitter battery; Adjust camera's audio input level. |
| Short operating range | Obstacles between units; Weak signal due to environment; Low batteries. | Ensure clear line of sight; Avoid operating in heavily obstructed areas; Replace batteries. |
