Walkie talkies work on the principle of simple physics, where we convert audio signals into radio signals via antenna, then another walkie talkie decodes the radio signals into voice signals.
A walkie-talkie's build quality and antenna quality determine the quality of the voice heard. Install two 9-volt batteries in each walkie-talkie (included).
They can be used as soon as possible. On each walkie-talkie, there are two buttons. As you speak, always press the left side of the transmitter (which activates it). Press the right-side button to either turn on or turn off the unit. ABS plastic is the material of choice
