What is the VOX function of the radio transmitter?

To enable and disable the VOX function, you need to perform a short press on the D button (1 second) on the SONR radio.

The VOX function allows transmitting audio from the radio to the receiver without pressing the receive (C) button. This means that when this function is activated, your radio will switch to a continuous sound transmission mode (continuous signal) to all receivers in the vicinity, on the same channel as the radio. It's important to know that with the VOX function turned on, your radio's battery will deplete approximately 2.5 times faster, as the device will operate without pauses. Additionally, every 30 seconds, the radio will send a single sound signal (beep) to the receiver to ensure that the receiver is on and receiving sound.
