2. Setup Instructions

2.1 Unboxing and Initial Charge

Upon unboxing, ensure all components are present: Transmitter(s) (TX), Receiver (RX), and Charging Case. It is recommended to fully charge the transmitters and receiver using the provided charging case before first use.

• Place the transmitters and receiver into the charging case.
• Connect the charging case to a USB-C power source (DC 5V/2A) using a compatible cable.
• Charging indicators on the devices will show charging status. A full charge typically takes approximately 2 hours for the case and individual units.

2.2 Connecting the Receiver

The receiver is designed to connect directly to your smartphone or compatible device. For the Lightning version, plug the receiver into the Lightning port of your iPhone or iPad.

2.3 Automatic Pairing

The BOYA system features automatic pairing. Once the transmitters are powered on and the receiver is connected to your device, they should automatically establish a connection. A solid indicator light on both the transmitter and receiver typically signifies a successful connection.

3. Operating Instructions

3.1 Powering On/Off

To power on a transmitter, press and hold the power button until the indicator light illuminates. Repeat for all desired transmitters. To power off, press and hold the power button again until the light turns off.

3.2 Microphone Placement

Attach the transmitter to your clothing using the rotating clip. For optimal sound capture, position the microphone approximately 6-8 inches (15-20 cm) from your mouth. The omnidirectional polar pattern captures sound from all directions, providing flexibility in placement.

3.3 Noise Cancellation

The system features intelligent noise cancellation. To activate or deactivate noise cancellation, press the dedicated noise reduction button on the transmitter. The indicator light will change color (e.g., static green for enabled, static blue for disabled) to confirm the status.

3.4 Monitoring Audio and Smartphone Speaker Support

When the receiver is connected to your smartphone, you can monitor the audio through headphones connected to the receiver's monitoring port (if available) or directly through the smartphone's speakers. If your phone's speaker is enabled, sound can be played directly without unplugging the receiver.

4. Maintenance

4.1 Cleaning

Wipe the microphone transmitters, receiver, and charging case with a soft, dry cloth. Do not use liquid cleaners or solvents, as these can damage the devices. Ensure no moisture enters the ports or microphone capsules.

4.2 Storage

Store the system in its charging case or a protective pouch when not in use. Keep it in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Avoid storing near strong magnetic fields.

4.3 Battery Care

To prolong battery life, avoid fully discharging the devices frequently. If storing for an extended period, charge the batteries to approximately 50% every few months.

5. Troubleshooting

• No Sound Output:
  • Ensure both transmitter(s) and receiver are powered on and fully charged.
  • Verify the receiver is securely connected to your recording device.
  • Check the recording app settings on your smartphone to ensure the external microphone is selected.
  • Confirm the devices are paired (indicator lights are solid). If not, power cycle both units.
• Poor Audio Quality/Interference:
  • Ensure the microphone is positioned correctly and not obstructed.
  • Activate noise cancellation if in a noisy environment.
  • Move closer to the receiver to reduce the transmission distance.
  • Avoid environments with strong 2.4Ghz interference (e.g., Wi-Fi routers, other wireless devices).
• Short Battery Life:
  • Ensure devices are fully charged before use.
  • Battery performance may degrade over time with extensive use.
• Devices Not Pairing:
  • Power off and then power on both the transmitter(s) and receiver.
  • Ensure they are within close proximity during the initial pairing attempt.
