2. Setup Instructions
- Identify the Connector: Locate the 3.5mm TRS mini jack connector at the end of the microphone cable.
- Connect to Audio Device: Plug the 3.5mm connector into the microphone input port of your compatible audio device (e.g., voice amplifier, speaker, tour guide transmitter). Ensure the connection is secure.
- Position the Headset: Gently place the ear clip over your ear and adjust the headband for a comfortable and stable fit on your head. The design is intended to be wear-resistant and prevent slipping.
- Adjust Microphone Arm: Bend the flexible microphone arm to position the microphone capsule approximately 2-5 cm (1-2 inches) from your mouth. This optimal distance helps capture your voice clearly and reduces plosive sounds. The arm can be rotated up to 270 degrees for precise placement.

3. Operating Instructions
Once the microphone is properly connected and positioned, its operation is primarily controlled by the connected audio device. The Retekess T130-T131 is a passive microphone and does not require separate power or controls.
- Power On Connected Device: Ensure your voice amplifier, speaker, or tour guide system is powered on and functioning correctly.
- Adjust Volume: Use the volume controls on your connected audio device to set the desired output level. Start with a low volume and gradually increase it to avoid feedback or distortion.
- Speak Clearly: Speak directly into the microphone at a consistent volume. The noise-reducing foam windshield helps maintain clear audio even in environments with background noise.
- Monitor Audio: If your audio device has a monitoring output, use headphones to check your sound quality and make any necessary adjustments to microphone position or device settings.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Retekess T130-T131 microphone.
- Cleaning: Gently wipe the microphone capsule and ear clip with a soft, dry cloth. For the foam windshield, you may carefully remove it and rinse with mild soap and water, ensuring it is completely dry before reattaching. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, store the microphone in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cable.
- Cable Care: Do not pull on the cable to disconnect the microphone. Always grasp the plug firmly. Avoid sharp bends or kinks in the cable, as this can damage the internal wiring.
- Handle with Care: While the microphone arm is flexible, avoid excessive force or repeated extreme bending to prevent damage.
