PRECAUTIONS FOR USE
- Keep your hand in the middle of the microphone to avoid damage to the frequency response or signal transmission.
- Avoid putting two transmitters next to each other to prevent interference.
- DO NOT point the microphone directly at the speaker to prevent feedback oscillation, commonly known as “howling.”
- To minimize intermodulation interference, keep at least 16 ft (5 m) between the wireless microphone receiver and transmitter.
- The receiving range is affected by many factors and varies greatly. Avoid large metal obstructions for better transmission.
- If the battery symbol flashes when the transmitter is in use, the battery is low and needs to be replaced.
- If the transmitter will not be used for a while, remove the battery to prevent microphone damage from battery leakage.
