Retevis RT56B Explosion-proof FRS two-way Radio
FRS radio, License-free
RETEVIS RT56B walkie talkies are FRS walkie talkies for Business use. They are license-free, no need to apply for a license to use it.
- They can work with other license-free radios easily, like the model Retevis RT22, RT21, and H777 on the same frequency and the same CTCSS/DCS.
Hard shell, Fully sealed and Explosion-proof
Retevis RT56B is a professional safe two-way radio for commercial use. It has 22 channels and an 1800mAh Li-ion battery, the especially safe design is perfect for the fire department.
The explosion-proof walkie-talkie is designed for workers who need safe communication tools, such as chemical plants, coal mines, gas stations, oil companies, fire stations,etc.
Also, this Explosion-Proof Radio is the best communication tool for Factories with a lot of dust. Such as flour mills, cement factories, and lime factories.
Product features are flammable dust explosion-proof, to meet the needs of different groups of users to communicate, and improve work efficiency.
There are 22 channels of Retevis RB56B License-free Explosion-Proof Walkie talkies. You may program the CTCSS/DCS easily via programming software. And this software is Free to download.
An explosion-proof walkie-talkie refers to a walkie-talkie that can work in a dangerous gas environment.
Different from the civilian walkie-talkie, the two-way radio relies on electromagnetic waves to transmit signals. In the process of conversion, it is easy to generate electric sparks, while the places where the explosion-proof walkie-talkie may generate sparks in the process of conversion are shielded, and the performance of the walkie-talkie is higher under special circumstances, and the conversation is clearer and brighter
