Museum, art gallery, library, enterprise exhibition hall, international exhibition and the place of guide for tour
Museum, art gallery, library, enterprise exhibition hall, international exhibition and the place of guide for tour
The introduction of product or publicity, service occasion
Visit of factory for high noise pollution
Team explanation of tour scenery spot for tour group
System characteristic:
1,2.4G wireless transfer technique, avoiding cellphone, WIFI SI, transmission distance of 80 meters.
2,Small appearance, comfortable to adorn with light weight .
3,Max supporting 30 channels and 30 languages, Isolation interference. And channels can be switched, listeners can select languages with switching channels.
4,Multi-languages operation system, simple operation, operation reminding shows Chinese,English, Being satisfied with multi-users.
5,Visitors may control the content by themselves, adjust visiting route and time
6,Requiring to have auto dormant function,energy saving and environment protection
7,Now it has covered the original labor explanation mode, which is the product of priority for the public of tour spot and museum.
8,With professional charging disinfection cabinet, booking both lithium battery charging and common dry battery to use. If using lithium battery, it can be chose to use charger and charging disinfection cabinet, charging disinfection cabinet may charge multi-explanation device one time, safty and health also enhancing the rate of charging.
9,Supplying SOYO monopoly algorithm to make sure that costomers`privacy are not violated.
