FAQ

Q1: How to quickly connect the transmitter and receiver of this 2.4GHz tour guide system?

A1: Just press the SET button on the transmitter to power it on, and the receiver will automatically power on and search for the transmitter's 2.4GHz signal to complete the automatic connection, without entering any pairing code or complex settings.

Q2: Is there any limit to the number of receivers connected to one transmitter?

A2: No, one transmitter can be paired with an unlimited number of receivers. The 2.4GHz high-frequency band transmission technology ensures stable audio transmission, and the signal will not be affected by the increase in the number of receivers.

Q3: Can the working frequency of the system be customized according to the use area?

A3: Yes, the default carrier frequency of the transmitter and receiver is 865MHz-880MHz, and we support customizing other frequencies according to the signal environment and relevant regulations of your use area, while the 2.4GHz anti-interference band remains unchanged.

Q4: How long can the system work continuously after a full charge, and is it suitable for all-day use?

A4: The transmitter can work continuously for more than 15 hours after a full charge, and the receiver can work for more than 8 hours. Both of them can meet the needs of all-day on-site explanation and use without frequent charging.

Q5: Can the receiver still receive signals normally when there are obstacles such as walls and glass in the use scene?

A5: Yes. The system adopts 2.4GHz high-frequency band and special U-band radio wave circuit processing, with strong signal penetration and anti-interference ability. The receiver can receive clear signals normally even with general obstacles such as walls and glass in the middle.
