4. Setup Instructions

4.1 Initial Preparation

1. Remove Protective Partition: Upon receiving the product, locate and remove the protective partition from the charging port of each microphone. This partition prevents dust and debris during shipping. Failure to remove it will prevent charging.
2. First-Time Charging: For optimal battery performance, fully charge the microphones and charging case before first use. The initial charge may take longer than subsequent charges as the battery management system initializes. Refer to Section 6 for detailed charging instructions.

4.2 Connecting to Your Device (Plug and Play)

The GRENARO S13 system is designed for simple plug-and-play operation:

1. Connect Receiver: Plug the Type-C receiver directly into your recording device's Type-C port. If using an iOS device, first attach the Lightning adapter to the Type-C receiver, then plug the adapter into your iOS device.
2. Power On Microphones: Take the wireless microphone transmitters out of the charging case. They will automatically power on and attempt to pair with the receiver.
3. Verify Connection: Once successfully paired, the red indicator light on the receiver and the green indicator light on the microphone(s) will remain steadily on. You are now ready to record audio.

5. Operating Instructions

5.1 Noise Reduction Function

The GRENARO S13 features a DSP intelligent noise reduction chip with three adjustable levels:

• Adjusting Levels: While the microphone is connected and active, short press the power button on the transmitter to cycle through the noise reduction levels.
• Level 1: Green light flashes once. Suitable for environments with minimal background noise.
• Level 2: Green light flashes twice. Provides moderate noise reduction for slightly noisy settings.
• Level 3: Green light flashes three times. Offers maximum noise reduction for very noisy outdoor or public environments.

5.2 Audio Modes

The microphone supports different audio modes for various recording scenarios:

• Noise Reduction Mode: Ideal for vlogging, podcasts, and YouTube content where clear speech is paramount.
• Reverb Mode: Suitable for video recording, live streaming, or singing, adding an echo effect. To activate, press the power button three times quickly on the transmitter when connected.
• Mute Mode: For interviews or meetings where temporary silence is needed.

6. Charging Instructions

6.1 Charging the Microphones and Case

• Place the microphone transmitters and receiver into the charging case.
• Connect the charging case to a power source using the provided USB to Type-C cable.
• The digital LED display on the charging case will show the current battery percentage, indicating charging status.
• Each microphone can provide up to 8 hours of continuous use after approximately 1-2 hours of charging within the case. The charging case itself provides multiple recharges, extending total usage time to about 30 hours.

6.2 Important Charging Tips

• First-Time Charge: The initial charge may take longer as the battery management system calibrates. This is normal and ensures optimal battery health.
• 80% Charge Calibration: When the battery reaches approximately 80% charge, the internal software may perform a calibration, causing the display to remain at 80% for about 20 minutes. After this calibration, charging will resume, reaching 100% in approximately 40 minutes (10 minutes to resume charging, then 30 minutes to full).

7. Compatibility and Android Specific Notes

7.1 Device Compatibility

The GRENARO S13 Wireless Microphone is compatible with a wide range of devices:

• iOS Devices: iPhone and iPad via the included Type-C to Lightning adapter.
• Android Devices: Smartphones and tablets with a Type-C port that supports OTG (On-The-Go) functionality.
• Laptops: Devices with a Type-C port.
• Note: This microphone system does not support devices with a Micro USB port.

7.2 Android User Considerations

Some Android devices may require specific settings or applications for optimal performance:

• OTG Feature: If the microphone connection is unsuccessful, ensure the OTG (On-The-Go) feature is enabled in your Android device's settings. This feature allows Android phones to connect directly to external devices. Some models may require manual activation.
• Default Camera App: If your device's default camera application does not recognize the external microphone, you may need to download a third-party video recording application. The "Open Camera" app is a recommended alternative. Within the "Open Camera" app, navigate to Settings > Video Settings > Audio Source, and select "External mic (if present)".

8. Troubleshooting

• Microphone not connecting:
  • Ensure the receiver is fully inserted into your device's port.
  • Confirm the microphone transmitters are powered on (green light steady).
  • For Android devices, check if OTG is enabled in your phone settings (refer to Section 7.2).
• No audio recorded:
  • Verify the microphone and receiver are successfully paired (indicator lights steady).
  • Check your recording application's audio input settings. For some Android devices, a third-party app like "Open Camera" may be required (refer to Section 7.2).
  • Ensure the microphone is not in Mute Mode.
• Poor audio quality/excessive noise:
  • Adjust the noise reduction level on the microphone to suit your environment (refer to Section 5.1).
  • Ensure the microphone is positioned correctly, typically clipped near the mouth.
  • Check for strong electromagnetic interference sources nearby.
• Microphone not charging:
  • Confirm the protective partition has been removed from the microphone's charging port (refer to Section 4.1).
  • Ensure the charging cable is securely connected to both the case and a power source.
  • Check the charging case's digital display for battery indication.
