FAQ

Q1: What is the maximum communication distance of the system?

A1: The maximum effective communication distance of the system is 200 meters in an open and unobstructed environment; the communication distance may be slightly shortened in a closed environment with many obstacles (such as walls, metal).

Q2: How many receivers can one transmitter be paired with at most?

A2: There is no upper limit on the number of paired receivers for one transmitter, which can meet the explanation needs of large-scale groups such as hundreds of people.

Q3: How long does it take to fully charge the transmitter and receiver?

A3: Both the transmitter and the receiver take 2.5 hours to be fully charged, and the charging box can charge multiple devices at the same time with the same charging efficiency.

Q4: Can the system be used normally outdoors?

A4: Yes, the system is designed with dustproof and anti-sweat, and the 2.4GHz signal is not affected by outdoor sunlight and weather (excluding extreme bad weather), and can be used freely indoors and outdoors.

Q5: What should I do if the receiver cannot receive the signal of the transmitter?

A5: First, check whether the transmitter and the receiver are in the same channel; if not, adjust the channel to match. Second, check whether the battery of the two devices is sufficient; if the battery is low, charge it in time. Third, check whether there is a strong interference source around; if so, move to an open area to use.

Q6: Is the microphone a standard accessory? Can I choose a different type of microphone?

A6: The plug-in microphone is a standard accessory, and the system is reserved with a universal microphone interface, which is compatible with most head-mounted microphones and plug-in microphones on the market, and customers can choose and match them by themselves.
