Products Description
This Portable Anti-interference Wireless Tour Guide System L7 is tailor-made for museum scenarios, developed to solve the pain points of unclear commentary, crowd interference, and limited mobility during group visits. It supports real-time audio transmission between guides and visitors, with a compact and lightweight design that ensures easy carrying throughout the museum. The system operates in the 2.4GHz high-frequency band to avoid signal interference from other devices, letting every visitor clearly hear the guide’s explanation of cultural relics and exhibition details. It is also suitable for extended use, thanks to its long battery life, fully meeting the needs of daily museum tours, temporary exhibitions, and academic exchange activities.

Product features
Portable Design: Both transmitter (48g) and receiver (16g) are ultra-lightweight, with a compact size that fits in the palm or can be clipped to clothing—no burden for long walks in museums.
Strong Anti-interference: The 2.4GHz high-frequency band ensures stable signal transmission, free from interference from mobile phones, Wi-Fi, or other wireless devices in the museum.
Simple Operation: Press the “SET” button on the receiver to power on and automatically search for the transmitter’s signal; no complex setup is required, saving time for guide preparation.
Clear Display: The transmitter is equipped with a full-function LCD screen, showing real-time information such as channel, volume, battery level, and signal strength—easy to monitor and adjust.
Long Battery Life: Powered by polymer lithium batteries, the transmitter supports up to 20 hours of use, and the receiver up to 8 hours—enough for a full day of museum activities.

Application
Primary: Museum guided tours, cultural relic explanation, temporary exhibition commentary, and academic exchange events in museums.
Extended: Enterprise visits, school educational tours, and high-end exhibition receptions (with a focus on museum-related scenarios).

Product Details
Transmitter: The full-function LCD screen uses high-brightness display, which is clearly visible even under the bright lighting of the museum; the “MUTE” and “CHANNEL” buttons are independently designed for quick operation.
Receiver: Adopts a non-in-ear wearing design (such as a clip-on earpiece), which is comfortable and does not block ambient sounds—visitors can hear the commentary while being aware of the museum’s environment.
Charging Box: Equipped with intelligent charging management, it prevents overcharging and overheating; the 220V universal input is suitable for different power supply environments in museums.
Storage Box: The all-aluminum outer frame is sturdy and anti-collision, and the built-in silicone groove fits the receiver perfectly—reducing vibration during transportation and facilitating unified storage of equipment after museum use.

FAQ
1. Q: Can multiple transmitters be used simultaneously in the same museum hall?
A: Yes. Each transmitter can be set to a different channel (up to 150 channels), and receivers can connect to the corresponding channel—suitable for multiple tour groups in the same hall.
2. Q: What is the effective communication distance between the transmitter and receiver?
A: The effective distance is ≤200m in an open environment; in a museum with walls or exhibits, the distance is slightly reduced but still meets the needs of most exhibition halls.
3. Q: How long does it take to fully charge the transmitter and receiver?
A: Both take about 2.5 hours to fully charge; the charging box has an indicator light to show the charging status.
4. Q: Is the receiver suitable for children or elderly visitors?
A: Yes. The receiver’s non-in-ear design is easy to wear, and the volume can be adjusted freely—suitable for visitors of different ages.
