5. Operating Instructions
5.1. Basic Operation
- Power On/Off: Press and hold the power button on the TX transmitter for 2 seconds.
- Wearing the Transmitter: Clip the TX transmitter to your shirt or clothing. For optimal sound, position the microphone approximately 6-8 inches from your mouth.
5.2. Gain Control
Use the + and - buttons on the TX transmitter to adjust the microphone's input gain. There are 12 steps of gain control to achieve optimal audio levels for different recording environments and speaker volumes.
5.3. Active Noise Cancellation (NR)
Press the NR button on the TX transmitter to activate or deactivate the active noise cancellation feature. When activated, the system will reduce ambient background noise, providing clearer audio, especially in noisy environments.
5.4. Muting
Press the MUTE button on the TX transmitter to temporarily mute the microphone. Press it again to unmute.
5.5. Connecting External Audio Sources
The 3.5mm TRS input on the TX transmitter allows you to connect external lavalier microphones, headset microphones, or even line-level audio devices (e.g., music players, mixers) for wireless transmission. Ensure the input mode is correctly set on the transmitter if using a line-level source (refer to advanced settings if available, though the Blink 100 series typically auto-detects mic input).
5.6. Powering Your Mobile Device
The RXUC receiver features a USB-C pass-through charging port. This allows you to charge your mobile device simultaneously while the receiver is connected and in use, ensuring extended recording sessions without draining your device's battery.

7. Troubleshooting
7.1. No Sound or Low Audio Level
- Ensure both the transmitter (TX) and receiver (RXUC) are powered on and successfully paired (solid blue indicator light).
- Check the microphone gain level on the TX transmitter using the +/- buttons. Increase the gain if the audio is too low.
- Verify that the RXUC is securely plugged into your recording device's USB-C port.
- Confirm that your recording application or device settings are configured to use the external microphone input.
- If using an external lavalier, ensure it is properly connected to the TX's 3.5mm TRS input.
7.2. Poor Sound Quality / Interference
- Activate the Noise Reduction (NR) feature on the TX transmitter if recording in a noisy environment.
- Ensure there are no obstructions between the transmitter and receiver, and try to maintain line-of-sight within the 164-foot (50m) range.
- Avoid operating near other 2.4GHz wireless devices (Wi-Fi routers, other wireless mics) that might cause interference.
- Check the furry windscreen is properly installed on the TX's built-in mic when recording outdoors to minimize wind noise.
7.3. Pairing Issues
- Power cycle both the TX transmitter and RXUC receiver.
- Ensure both units are within close proximity during initial pairing.
- The system is designed for automatic pairing. If issues persist, refer to the full Saramonic support documentation online.
7.4. Device Not Charging via RXUC Pass-Through
- Ensure the charging cable is securely connected to both the RXUC's pass-through port and a working power source.
- Verify that your mobile device supports charging via its USB-C port while an accessory is connected.
8. Maintenance
- Keep the devices clean using a soft, dry cloth.
- Avoid exposing the devices to extreme temperatures, humidity, or direct sunlight.
- Store the system in the provided carrying pouch when not in use to protect it from dust and damage.
- Do not attempt to disassemble or repair the device yourself, as this will void the warranty.
