210-1846 GMRS/FRS Intercom Base Station 2-Way Personal Radio===Using Vox===VOX allows you to transmit hands free. To activate VOX press the [VOX] button. This toggles between VOX on or off. A quirk with this model is that although a short-press of the [VOX] button will enable VOX, it will not always disable it. A long-press of the [VOX] button activates the feature menu. To disable VOX you have to press the [VOX] button a bit longer than the short press that activates VOX, and not quite as long as it takes to de-activate VOX. Again, this is a glitch in some models.
