After turning on the VIMaiTong V9S, press the intercom buttons of two walkie-talkies to switch to Bluetooth intercom mode, and a voice prompt of "two people" will be given after the connection (Bluetooth intercom mode does not limit the number of people). In addition, there is Bluetooth intercom friend mode, which is the private friend mode of our team. The others can't be connected. When two walkie-talkies switch to this mode at the same time, they will also say "two people" after connection. There is also a Bluetooth intercom dual mode, which is a one-to-one front and rear seat intercom mode. Two walkie-talkies switch to this mode at the same time, and after the connection is successful, there will be a voice prompt of "walkie-talkie headset connected".

The English name of walkie-talkie is twowayradio, which is a two-way mobile communication tool. It can make calls without any network support, and there is no telephone charge, which is suitable for relatively fixed and frequent calls.

V9S two-person intercom can reach 500 meters, with good sound quality, noise reduction function and Hi-Fi support.
