5. Installation and Usage

5.1. Pairing

All units are pre-paired at the factory. If re-pairing is needed, follow these steps:

1. Ensure both transmitters and the receiver are turned on. If the receiver's display is dim, short press any button to light it up.
2. Long press both pairing buttons on the receiver simultaneously until the display shows “PAIR”.
3. Long press the pairing buttons on the two transmitters respectively until they get paired. During pairing, the indicators on the transmitters will blink blue rapidly.
4. Once paired, the indicators on the transmitters will show solid blue, and the receiver's display will show the status of the transmitters.

If one of the transmitters is not paired, turn off the already paired transmitter first and then follow the steps above to pair the unpaired one. Once it is paired, turn on the other paired transmitter to use both.

5.2. Transmitter Installation

Install the transmitter on your collar so that the internal microphone points towards the sound source for optimal audio capture.

5.3. Output Methods for Receiver

Analog Output (Camera)

Attach the receiver to your camera's hot shoe mount using the belt clip. Connect the receiver to the camera's audio input using the 3.5mm TRS-TRS audio cable.

7. Troubleshooting

• Q: Can I use the stereo mode on my phones or laptops?
  A: No, you can only use the mono mode on your phones or laptops, as an extra adapter is typically required for connection, which often limits to mono output.
• Q: How do I connect it to my iPhone?
  A: For iPhone users, connect a 3.5mm to Lightning adapter with OTG to the receiver. Note that the iPhone speaker may not work when connected.
• Q: How do I connect it to my computer?
  A: To connect VIMO C3 to a computer with USB-C input, use a 3.5mm to USB-C audio adapter (not included) or a TRS-TRS cable. Make sure to select VIMO C3 as the input audio device in your computer's sound settings and recording software.
• Q: What should I do if my camera has loud background noise?
  A: Manually adjust the camera's recording volume, lower the camera's gain, and turn off automatic gain control. Note: Vimo C may not be compatible with your camera's built-in wind noise suppression and noise reduction functions. Turn off both functions on your camera when recording with the Vimo C.
• Q: How is the sound quality? What is the difference with other products?
  A: The Vimo C has a high recording standard of 48kHz sampling rate and 24-bit sampling accuracy, providing a radio effect that is better than CD-level sound quality.

8. User Tips

• Optimal Placement: For best sound clarity and quality, position the microphone approximately 20 cm away from the mouth.
• Gain Adjustment: Experiment with the 4-level gain control to find the ideal volume for your recording environment and avoid over-amplification.
• Noise Cancellation: Utilize the one-key noise reduction feature in noisy environments to filter out unwanted background sounds.
• Battery Management: The charging case provides extended battery life up to 20 hours total. Remember that the units can be used while charging, offering flexibility during long recording sessions.
• Automatic Operation: Take advantage of the automatic pairing and power on/off when using the charging case for a seamless workflow.
• Compatibility: While highly compatible, ensure you have the correct adapter cables (e.g., 3.5mm to Lightning, 3.5mm to USB-C) for your specific smartphone or computer if not included in your package.

9. Maintenance

• Cleaning: Use a soft, dry cloth to clean the microphone and receiver. Avoid using liquids or abrasive cleaners.
• Storage: Store the device in its charging case when not in use to protect it from dust and physical damage.
• Battery Care: For long-term storage, ensure the battery is partially charged (around 50%) to prolong its lifespan. Avoid fully discharging or fully charging for extended periods.
• Environmental Conditions: Do not expose the product to extreme temperatures, high humidity, or direct sunlight.
