5. Operating Instructions

5.1 Connecting to Audio Devices

The receiver can be connected to various audio devices using the appropriate adapter:

• Amplifiers, Mixers, PA Systems, Speakers: Insert the receiver's 3.5mm plug directly into the device's MIC INPUT. If the device has a 6.35mm input, use the included 6.35mm adapter.
• Smartphones/Tablets: Use the included splitter. For iPhones, an original Lightning to 3.5mm adapter (not included) is required. For Android devices, a Type-C to 3.5mm adapter (not included) may be needed depending on the phone model.
• Laptops/Computers: A USB sound card (not included) is required for connection.

5.2 Recording on Smartphone

When recording on a smartphone, the phone itself cannot output sound while the microphone is in use. You will need to use headphones or unplug the splitter to listen to the audio.

5.2.1 Audio Recording

Use your phone's built-in recorder app or any third-party recording application with the phone adapter.

5.2.2 Video Recording

• For Android Phones: Download the "Open Camera" app from your app store. This app supports external microphones via the splitter. Navigate to Open Camera app settings > Video Settings > Audio Source > External Mic (If Present).
• For iPhones: The phone's built-in camera app supports external microphones directly.

5.3 Volume Control

The headset features volume control buttons for adjusting the audio output level directly on the device.

6. Maintenance

• Cleaning: Wipe the microphone and headset with a soft, damp cloth after each use, especially after exposure to sweat or water.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying bag for protection.
• Water Immersion: While the device is waterproof, avoid immersing it in deep water or salt water for extended periods, as this may cause corrosion to the charging port over time. Always ensure the magnetic charge port is sealed with the rubber plug when exposed to water.

7. Troubleshooting

• No Sound or Low Volume:
  - Ensure both the transmitter and receiver are powered on and successfully paired (steady indicator lights).
  - Check all cable connections to the audio device. Ensure they are secure.
  - Verify the audio device (speaker, PA system) is powered on and its volume is adjusted appropriately.
  - For optimal sound, the connected speaker or PA system should have a power output above 100W and not less than 15W.
• Pairing Issues:
  - Turn off both devices, then turn them back on by long-pressing the power button for 3 seconds. Allow them to auto-connect.
• Recording on Smartphone/PC:
  - Remember that smartphones/laptops typically cannot output sound while recording with an external mic. Use headphones or unplug the splitter to monitor/playback audio.
  - For iPhones, ensure you are using an original Lightning to 3.5mm adapter.
  - For laptops/PCs, a separate USB sound card is required for proper functionality.
• Interference/Poor Signal:
  - Ensure you are within the 65ft (20m) wireless range in an open area.
  - Avoid obstacles that may block the signal.
• Water Damage Concerns:
  - Always ensure the rubber plugs are tightly sealed on the magnetic charge port before exposing the microphone to water.
