Simple DIY trouble shooting

1. Adjust the Direction or Position of the Receiver: Ensure that the infrared receiver is correctly positioned and aligned with the microphone to maintain a strong connection.
2. Check the Microphone Battery Level: Verify that the infrared microphone has sufficient battery power, as low battery levels can reduce the effective range.
3. Inspect the Connection Cables: Examine the cables connecting the receiver for any loose or faulty connections. Ensure that all cables are securely plugged in, and consider replacing them if they appear damaged or worn.

1. Power Switch Not Fully Engaged: Ensure that the power switch on the microphone is fully turned on.
2. Battery Contact Issues: Check if the battery contacts (battery springs) are properly connecting with the battery. If not, adjust them to ensure a secure connection.
3. Incorrect Battery Installation: Verify that the batteries are installed correctly and that the polarity is not reversed.
4. Depleted Battery: Replace the battery if it is fully drained.

1. Check the Direction or Position of the Receiver Sensor: Ensure that the infrared receiver sensor is properly aligned with the microphone's infrared transmitter. Adjusting the direction or position can help reduce noise.
2. Fine-Tune the Noise Setting: If your system allows, slightly adjust the "NOISE" control to minimize background noise.
3. Avoid Obstructing the Infrared Signal: Ensure that your hand or any object does not cover the infrared sensor transmitter on the microphone, as this can cause interference and result in noise.

Infrared microphones rely on the principle of infrared light refraction to transmit signals, which means they are designed for indoor use only. Infrared signals are easily disrupted by sunlight and other outdoor conditions, making them unsuitable for outdoor environments. These microphones are best used in enclosed spaces like school classrooms or KTV rooms, where the infrared signals can effectively transmit without interference from external light sources.

1. Adjust Receiver and Sensor Position: Ensure that the receiver's sensor, including any external IS-20 or IS-30 sensors, is positioned correctly and oriented to maximize reception.
2. Check Battery Level: Confirm that the infrared microphone's battery has sufficient power. Low battery levels can significantly reduce the transmission range.
3. Inspect Connection Cables: Verify that the connection between the receiver and the sensor (including external IS-20 or IS-30 sensors) is secure. Check for any loose or poorly connected cables, and replace the connection cable if necessary to ensure proper signal transmission.
