FAQ about Explosion-proof walkie-talkie
Q1: What specific hazardous environments are KTW386 intrinsically safe intercoms suitable for?
A1: KTW386 has passed multiple explosion-proof certifications and can be safely used in coal mines, chemical plant zones 1 and 2, oil tank areas, gas stations, pharmaceutical factories, and other places. It is suitable for Class IIA and IIB gas environments and combustible dust environments. Whether it is a coal mine containing explosive mixtures such as methane and coal dust, or a chemical production area with strict requirements for explosion prevention, it can work stably.
Q2: How far can the intercom distance of this walkie talkie reach in actual use?
A2: In outdoor open environments, the intercom distance of KTW386 is 1-3 kilometers. However, in actual use, the intercom distance may be shortened due to obstacles such as buildings and terrain. For example, in urban blocks with high-rise buildings or complex mountains, communication distance will correspondingly decrease.
Q3: What are the advantages of designing split cell batteries? How is it different from traditional all-in-one batteries?
A3:The split battery design allows for the addition of batteries at any time. When the battery fails, it only needs to be replaced without scrapping the entire machine, greatly reducing the cost of use. Once the traditional all-in-one machine battery is damaged, it often requires replacing the entire walkie talkie, which not only incurs high costs but also affects normal use.
Q4: What should I do if I encounter equipment failure during use?
A4: If the device malfunctions, you can first refer to the troubleshooting guide in the product manual and try to solve it yourself. If the issue cannot be resolved, you can contact the brand after-sales service center and provide the product serial number and fault details. Professional after-sales personnel will assist with repairs or provide solutions to ensure the normal use of the equipment.
