Unwired UFRBS10 2-way radio

How do you disable VOX on this unit?? I bought the unit with no instruction manual. It transmits at the slightest noise. Useless for receiving. The "mode" button offers a change of channels, change of subcodes, and "off" and "on". I would think that this would be VOX selection, but it seems to have no effect. What am I turning off and on?

I have a Kenwood tk-2212L. I am unable to transmit via my lapel PTT microphone. I can however hear dispatch & other units. How do I activate VOX? Any suggestions?

Not all devices are VOX compatible. Some audio accessories with inline PTT buttons fall in this category. One thing you can do is be certain to have the radio turned off when plugging in the device. Check your user guide for VOX instructions and double check the compatibility of lapel mic.

In order to use VOX on your radio you will need a VOX capable accessory OR you can use iVOX which allows you to use talk hands free without an accessory. The instruction for both these features can be found on page 22 in the user guide.
You will need to fill in the "dot" with a "." because Fixya is not allowing insertion of links currently: giantintl dot com/ContentManage-new/manuals/Moto/T65xx.pdf
Keep in mind when using VOX the radio will open up its transmitter with any noise, not just exclusively voices. So if you are in a high noise environment you will not be able to use VOX or iVOX.
Best regards.

How do you disable the VOX setting on a Talkabout MR350 2 way radios. I wan to use it with a headset, but do not want VOX on.

Here is a link to the user guide: You will find the instructions for VOX and iVOX on the bottom of page one, and at the beginning of page 2.

Be certain when plugging in your audio accessory that the radio is turned off. If the radio is left on inadvertently, you would have no control over the VOX settings, it would immediately be in a confused VOX mode.

Also, with most Motorola radios, if VOX begins to occur, turn off the radio, and then re-insert the audio device plug. And in some instances, pressing the PTT on the radio when you are having a VOX occurrence will put the radio back to push-to-talk status.

Best regards.

I have set the two radios to match each other , problem is when I plug the headset in it will not transmit. I just bought them yesterday. Why do the transmit with the radio but not the headset mike.

1) Be certain you are plugging in the headset with the radio turned off.
2) Be certain the headset is one designed to go with the radio if purchased separately.
3) If the headset has an inline PTT, use it, not the one on the radio
4) Also, check your VOX settings, to assure it is set the way you would like, including VOX sensitivity.

Best regards.

Hello I just bought a Motorola 53725 SLK Headset with Swivel Boom Mic (Black) for my Motorola FV200AA 5-Mile and I have a problem to hear. They can hear me but I cant

Two things to check. Make certain you are plugging in the headset with the radio shut OFF. Also be certain the headset is plugged in all the way. You should feel a slight click when it is seated properly.

If the headset has an in-line PTT, don't alternate between it and the one on the radio. If there is no in-line PTT, use the PTT on the radio unless you have your radio set for VOX.

If using VOX mode, do not touch the PTT at all once you turn the radio on. One thing to keep in mind if using VOX, the receiver will pick up any ambient noise around you and think it is voice and keep your radio locked into transmit. Vox only works well in a somewhat quiet environment.

I've probably given you more info than needed, but wanted to cover all the bases.

How do I set my sx700 radio to work with hands-free headsets? Any assistance would be appreciated.

Hands-Free Use With Accessories (VOX)
You can transmit hands-free with the use of optional accessories. Once
VOX is turned on, the radio detects your voice and transmits when you
1. Turn the radio off and plug the VOX accessory into the accessory
2. Turn the radio on. VOX shows on the display.
3. Adjust the volume appropriately by rotating the volume knob . Lower the volume
before placing the accessory on your head or in your ear.
4. To turn off, simply remove accessory.
Note: There is a short delay between the time you start talking and
when the radio transmits. There is a short delay before the
transmission is completed.

Owners Manual:

You must be using a VOX capable accessory. Generally this is an accessory without an in-line PTT.

Motorola T5622 VOX Not Activating with Autocom Sys I have an Autocom (Kit 300) motorbike coms system. I bought the accessory cord that interfaces to the Motorola T5622, for VOX I have followed the Motorola...

Hi Folks, two seperate checks to do - to check vox on autocom and transmit on motorola. With the T5622 unconnected to anything, does the push transmit button work - e.g. does it make the beep noise at the end of transmission?

Does your autocom work with any other sound sources - i.e. mp3 player so you can hear music. Does this mute when you speak ? (it should if vox is working). Note that in this setup vox is provided by autocom - NOT BY THE T5622. The instructions you mention are for the motorola vox kit.

Wire the two together and you should get the motorola beeping through your autocom at the end of transmit - that's what my kit 200 does with my T5622.

If you are using vox (voice activated transmit) go into the menu and make sure you don't have the VOX setting too high. You should be able to put the headset on... hit the "push to talk" button on the radio and transmit you audio. Turn the other radio on and make sure the radio is "keying" (tx with no auio) then make sure there is audio. If you don't have audio but the radio is transmitting.. you might have the wrong type of plug on your headset for the audio..... there are 2 plugs... 1 for transmit audio....1 for recieve audio. It could be the wrong type of plug for the jack in the radio. Regardless.. the way the headset works is either you push the "push to talk button" onj the radio OR you use the VOX function... with the vox function you just have to talk into the mic to transmit. This is what your headset is designed for. You will have to go into the menu and set up the radio for VOX. If you still have problems follow my directions at the top of this page ( check mic jack and stuff) I think you just have to set the radio up for VOX operation and set the VOX setting. You should be able to push the push to talk button and talk through the mic on the headset. If you don't get any audio that way there is a problem and you should check the jack and plug on the headset.
