What is the VOX function?
Voice operated exchange is referred to as VOX. Generally, when using a walkie-talkie, unlike a mobile phone, a walkie-talkie generally needs to press a button to send voice. This button is called the Push to Talk (PTT) button.
If VOX is turned on, there is no need to press the PTT call button. As long as the microphone of the walkie-talkie detects the voice, it will automatically start transmitting, realizing "voice-controlled" calls. When the microphone cannot hear the sound, it will be turned off: the greatest significance of VOX is that it can completely free your hands and make calls easily.
VOX sensitivity level
The higher the level, the more sensitive it is. If you do not talk for a long time, the call will be automatically disconnected. If you use the VOX function in a noisy environment, the walkie-talkie will definitely collect the surrounding background sound and transmit continuously. At this time, we can set the sensitivity level of VOX on the walkie-talkie only when the sound reaches the value that can trigger VOX, the walkie-talkie will be activated to transmit sound. In this way, the walkie-talkie can be prevented from collecting surrounding sounds to a certain extent.
Who needs VOX
As mentioned earlier, the biggest function of VOX is to completely free your hands. If you always feel cumbersome to press the call button when using a walkie-talkie, then VOX may make your conversation smoother.
Workers
When using tools with both hands, they can also use the walkie-talkie easily. Without VOX, you can only choose one to talk while working, which is time-consuming and laborious!
Security
When you find a safety problem, you only need to move your mouth to contact the main station in time, which greatly reduces the time to take out the walkie-talkie and press PPT. Without VOX, you take out the walkie-talkie and talk, and the thief will run away long ago!
Restaurant waiter
If there is a problem, you can also give feedback in time, and you are more flexible and free when serving dishes.
Without VOX, you will be in a hurry and easily cause unnecessary danger.
Outdoor sports
If you love extreme sports, like to make an appointment with a few friends to climb mountains and rock climbs, or the weather is cold, like to take your family skiing and skating, use the VOX function to free your hands while ensuring your own safety.
When using the ETMY walkie-talkie with standard VOX function, when the function is activated, you don’t have to press the PTT key, you can directly start the transmission operation by voice, which can effectively free the user’s hands.

CTCSS function on walkie-talkies covers a frequency range from 67.0Hz to 250.3Hz. When transmitting in analog sub-tone mode, it transmits by continuously superimposing low-frequency, inaudible signals onto the carrier frequency, ensuring that only receivers receiving the same frequency can interpret the signal. This achieves anti-interference capabilities or allows the receiver to reject signals from other third parties.
