谢谢 Lucky6 它是一种手持式，便携式的多路无线电设备，是为了和拥有无线电设备的人通讯而特别制造的。所以，如果你的无线电开着，并且在你的无线电信号范围内的其他人也开着他们的无线电设备，而且调到了相同的无线电频率或者频道，你们就能通过这些设备相互通讯。不过，你得小心，因为任何调到你的频率并且离你够近能获取你信号的人都可能听到你们的通话，即使他们没有参加你们的谈话。希望对你有帮助。

It's a hand-held, portable multi-way radio, made specifically for communicating with other people who have radios. So, if your radio is turned on, and other people within range of you have these radios turned on and tuned in to the same radio frequency, or channel, you can communicate with each other through the machines. You have to be careful, though, because anybody who is tuned in to your frequency and close enough to pick up your signal may be able to hear you, even if they're not part of the conversation. Hope this helps.
