​DMR, or Digital Mobile Radio, is a technology that allows for efficient and flexible communications over long distances. It offers superior sound quality, advanced features, and enhanced privacy and security compared to traditional analog radios.

If there is no sound or low sound during use of the walkie-talkie, you should first check whether the battery voltage is sufficient.

In today's era of rapid digital development, communication methods are constantly upgrading, and POC Radio is gradually becoming an important communication tool for industries such as enterprises, security, logistics, and property management. Compared to traditional intercom devices, POC Radio not only breaks through distance limitations, but also has rich intelligent functions, bringing a new solution for modern industry communication.

In the amateur section, there are very strict norms, and they will be specially trained when testing. At 409m exemption, there are the following provisions: 1.Do not change the transmitting frequency and increase the transmitting power (including additional radio frequency power amplifier) without authorization. 2.Do not cause harmful interference to various legitimate radio business when using. Once harmful interference is found, use it immediately, and take measures to eliminate interference before continuing to use it; *Using public intercom, its communication quality is not protected by radio management agencies, and the radio business that may work normally should be caused by other normal jobs; 3.It is forbidden to use on the airport and aircraft; 4.It is forbidden to interconnect with the public telephone network, public mobile communication network and other telecommunications networks.

One of the most important developments in the walkie-talkie industry is the integration of advanced features and technologies. Traditionally, walkie-talkies were simple two-way radios with limited range and functionality.

​A wireless walkie-talkie is a portable communication device that can communicate wirelessly in places without network coverage. Wireless walkie-talkies are often used in situations where instant communication is required, such as outdoor adventures, construction sites, security industries, etc.
