Re: Cobra PR4100-2 WXVP with VOX

Hi Dave,

On some other models/brands, you need to use an external mic/spkr such as a headset for the VOX to operate. This may or may not also work for your model. Perhaps you can try getting hold of a headset that will fit your model and see if it works.

If you are already using a headset:
1. If it is a compatible model, then something is wrong electronically with your unit and you will need the services of a qualified communications technician;
2. if it is a generic or some other brand/model, then the pins, jacks, plugs or connectors may not be wired to be compatible with your Cobras. You need to get Cobra compatible ones.

Hope this be of some help/idea. pls post back how things turnes ouot or should you need additional information.

Good luck and kind regards.

Uniden turn off vox

Hi Jon,
The problem is easy to solve, so here goes:
vox indicates that your unit is set to work via the microphone(if you have one), and is activated when you start to speak, (hence vox=voice activated microphone), if you don't have the microphone that came with the unit, you will need to buy/borrow one and connect it to the unit, before you can turn off vox, so that the unit can work with or without the microphone(vox will no longer show), once you have done this.
I hope this helps.

What does vox and rog. Stand for on the cobra microtalk

VOX is the abbreviation for Voice activated transmission, and ROG is likely the abbreviation for Roger Beep, which is a small beep or series of beeps at the end of a transmission that alerts the other person you are talking too that your transmission has ended. this is mostly used when signals are noisy, as the beeps are a sure sign that you have finished your transmission.

Can i have my UH064sx-2 Radio activate & send when i talk into it

AFAIK, this is only possible when you have the headset plugged in. The headset allows VOX operation (voice operated transmission). If there is nothing plugged in or the handset is plugged in, the VOX setting is automatically switched off.

You can adjust the sensitivity of the mic so that it will start transmission only when a certain sound level is exceeded. There is a tiny lag between when it detects the sound and when it starts transmitting.

Using headset jack - unit always transmits

Try plugging in headset BEFORE turning on radio. You should see the word VOX (not iVOX) on your display. At least this is what works for me.

Bell South 2250 one seems to be voice activated and other not voice activated.

To turn off sound activation press the menu button 3 times to enter VOX mode. The VOX icon should be flashing, then press the down button till the number of bars dissappear. Press the menu button to confirm the VOX off mode. You also can adjust the sensitivity of the VOX mode by how many bars are displayed, less bars equal less sensitivity. No bars and voice command is deactivated. Hope this helps.

Problem with Headphones


Can you pls add a few more details:
1. are the 2.5mm jacks stereo (3 pins) or mono (2 pins):
2. is your universal headset monaural or stereo; and
3. originally, did the universal headset came with 2 separate plugs?

At most that I can give you is a general/generic idea. The external speaker/microphone (or in your case the universal headset) uses also the charge jack, chances are that it is a multi terminal/pin jack. Pls refer to the diagram below.


The reason it is in continuous transmit is because one of the mini speaker is wired to the PTT trigger or the pins are wired wrong;

This would also explain why no transmit audio either manual or via VOX.

Hope this be of some help/idea. Post back how things turned up or should you need additional information.

Good luck and kind regards.

Radio is switched on vibrates and goes directly to a blank screen

The problem that you discribe, sounds weird, check if the radio battery connectors are clean, if the radios are new, I think you must to cliam the warranty.
