How to Use
For BY-V3, BY-V30, BY-V20, BY-V2, BY-V10, BY-V1 Combo Packages:
- Transmitters automatically turn on when removed from the charging case and can be attached to clothing via the belt clip.
- Connect the BY-V-RXU receiver to a USB-C device or the BY-V-RXD receiver to a Lightning device.
- Transmitters and receivers are pre-paired. They will pair automatically once the transmitter is on and the receiver is connected to the device. Indicators will show solid blue upon successful pairing.
- Launch a video or audio recording app on your device.
- Some phones may default to their internal microphone; switch to the external BY-V microphone if necessary.
- You are now ready to record.
For BY-V35 (for cameras):
- Transmitters and the BY-V-RX receiver turn on automatically when removed from the charging case.
- Transmitters and receiver are pre-paired. They will pair automatically once the transmitter is on and the receiver is connected to the device. Indicators will show solid blue upon successful pairing.
- Position the transmitter(s) on clothing using the belt clip.
- Using the Receiver:
- With a Camera: Connect the 3.5mm TRS output of the receiver to the microphone input of a camera using the provided 3.5mm TRS to TRS audio cable. Refer to the camera's user manual for recording.
- With a Phone: Connect the receiver to a phone via the USB-C data port using a suitable data cable. Launch a video or audio recording app on your phone to start recording. If the phone defaults to its internal microphone, switch to the external BY-V microphone.
Suggestions:
- Record a sample and play it back to check if the audio level is acceptable before recording.
- To improve recording in noisy environments, press the NR button on the transmitter to enable noise reduction.
Note on Wireless Performance: 2.4 GHz signals can be easily attenuated. Avoid obstacles like walls and buildings, and keep away from devices with 2.4 GHz signals such as high-power Wi-Fi antennas and radios.
Troubleshooting
- Unit fails to pair: Ensure transmitters are paired to a receiver.
- No sound from the unit or when connected to an external device: Ensure the receiver connector is properly connected. Ensure transmitters are not muted (slow blue flashing indicator means mute; press power button to unmute).
- Limited operating range and intermittent sound: Ensure there are no interferences between transmitters and receiver. If intermittent sound persists, contact customer service.
- Unit turns off automatically: When not paired, transmitters turn off automatically after 10 minutes.
- Unit fails to turn on: Ensure the unit's battery is sufficiently charged. Try connecting a charging cable.
- Charging case fails to charge the unit: Ensure the charging case battery is not depleted. Try charging the case. Clean charging contacts and pins with a clean cloth. Ensure the unit is properly seated in the charging case. If charging still fails, magnetic force may be worn out; contact customer service.
