FAQ
Q1: How to realize the signal pairing between the transmitter and the receiver of the L5 tour guide system?
A1: Press the SET button of the transmitter to power on, and the LCD display will show the working channel; then press the SET button of the receiver to power on, and it will automatically search and connect to the signal of the corresponding channel. If you need to switch the channel, adjust the channel number on the transmitter, and the receiver will automatically match the new channel after restarting (or support manual channel adjustment).
Q2: Is there a limit to the number of receivers that a single L5 transmitter can connect to?
A2: There is no upper limit to the number of receivers that a single L5 transmitter can pair with. It supports one-to-many unlimited connection, and the signal transmission is stable without being affected by the increase in the number of receivers, which is suitable for large-scale team explanation scenarios.
Q3: Can the receiver adjust the volume independently? What other sound adjustment functions are there?
A3: Yes, the receiver is designed with an independent volume adjustment button, which can adjust the volume at will according to personal listening needs; it also supports mute setting, which can realize one-key mute, and can adjust the sound sensitivity to adapt to different noisy use sites and achieve the best reception effect.
Q4: What is the actual use time of the L5 tour guide system after full charge? Can it be charged in time during use?
A4: After full charge, the L5-T transmitter can work for more than 30 hours, and the L5-R receiver can work for more than 35 hours, which can fully meet the all-day continuous use needs. The product is equipped with a portable HM-EG10 USB charger, which can charge the equipment at any time during use, and the batch charging box can also realize centralized fast charging of multiple devices after use.
Q5: What is the effective working distance of the L5 tour guide system? Will the signal be unstable in an open area?
A5: The effective communication distance of the transmitter is ≤100m, and the maximum receiving distance of the receiver is ≤150m. The product adopts UHF high-frequency band anti-interference design, with strong signal penetration and stability. Even in open areas such as scenic spots and factory areas, the signal transmission is stable without delay or disconnection, and there is no signal dead angle in the effective range.
