1. How far is the talk distance of the walkie-talkie?
There is no "distance" indicator for radio communication, because ultrashort wave communication is line-of-sight communication, and signals are blocked and interfered by buildings, hills, trees, electromagnetic fields, etc., affecting the actual call distance and quality. Under ideal conditions (without any blocking and interference), the distance of the professional walkie-talkie is even more than 10 kilometers, and the actual talk distance is generally only 3 to 5 kilometers. In the case of tall buildings, high mountains, or severe electromagnetic interference from space. Underneath, the call distance is sometimes short or even impossible to communicate.
2. Can mass consumers buy walkie-talkies?
Mass consumers can also buy walkie-talkies, but previously purchased and used walkie-talkies must apply to the local radio management committee (referred to as "no committee"), receive a radio license and pay a frequency occupancy fee. From December 6, 2001, China's open civilian walkie-talkie market, using 400MHz, the civilian walkie-talkie with a launch power of less than 0.5 watts, no need to go through any formalities.
3. Can the interphone be called?
The walkie-talkie can be used to make calls when there is network support. However, if it is only a regular call between the single machines, the function of making a call cannot be realized.
4. Is there a charge for talking on the intercom?
There is no charge for talking on a regular walkie-talkie. No matter how often you use it, you only need to pay a tens of dollars per year for each walkie-talkie. If you use a public walkie-talkie, you don't have to pay anything.
5. Why is there a frequency limit for using the walkie-talkie?
In order to ensure that most users do not interfere with calls and use frequency resources reasonably, the National Wireless Management Committee divides the use of frequencies and stipulates that different industries use corresponding frequency ranges. When purchasing a walkie-talkie, users should apply to the local radio management committee for frequency.
6. What should I do when the walkie-talkie enters the water?
During the maintenance, many repair machines were found to be water inlets, and it was found that such machines had different degrees of circuit corrosion due to improper handling after entering the water. Generally, the serious problems cannot be repaired, so the machine should be timely after entering the water. Disposal, including immediately unplugging the battery, force the water out, put it in a dry and ventilated place, and strive to send it to the repair station for repair in the shortest time.
