Does anyone know how to pair a walkie-talkie with a channel?

Many users don't know how to "pair" channels when using walkie-talkies. Next, let's learn about the related knowledge.

To pair a walkie-talkie with a channel, first turn the FM knob. Strictly speaking, there is no so-called "pairing" for walkie-talkies. Walkie-talkies use frequencies for calls, whether they are analog signals in the early years or digital signals later, and now Base station and IP intercom technology. Although the technology has changed, the frequency used has not changed. As long as one or more intercoms are set to the same frequency, the intercoms at that frequency can directly communicate, and For one-to-one or one-to-many calls, there is no such thing as "pairing". Just turn the adjustment button to adjust the frequency. 

The so-called "frequency" can be understood as TV channels and call channels. Based on different application industries, the frequency of the walkie-talkie There are strict restrictions. For example, the civilian U-band frequency is between 400-470MHz, and the V-band frequency is between 136-174MHz. Taking the 420MHz frequency, A walkie-talkie and B walkie-talkie as an example, as long as the frequencies of these two walkie-talkies are all Set to 420MHz frequency. 

As long as the communication distance does not exceed the range and there are no strong interference sources or obstacles within the communication range, the two walkie-talkies can communicate. The signal transmission during the call is limited to this frequency and will not affect other Device calls in frequency bands, such as the 350MHz frequency used by the police, the 220MHz frequency used by the coast; the 433MHz frequency used by amateurs; the 900MHz frequency used by mobile phones; the 85-120MHz frequency used by radios, etc. do not interfere with each other and do not require pairing. As long as the device has a frequency search function, it can receive or transmit signals by adjusting the frequency, and can also communicate at the same time.
