The three things which come to mind are:
1) Is the headset the VOX headset intended for the radio model? Sometimes the rings on the plug do not match the internal points of contact if it is not the intended headset. Not all headsets are VOX capable.
2) Is the headset plugged in all the way. (You mentioned plugging in and then turning on. This is good. You must always have the radio turned off when plugging or unplugging an audio device.)
3) Try pressing the PTT on the headset cord one time before switching the dip switch to VOX. (Assuming you have a headset with the small box in the line.)

Lastly, if you continue to have difficulties, contact Motorola at the 800# provided in the user guide. They should be able to assist you.

Check your VOX/ iVOX settings. You will need VOX for using an audio device.

Here is a link to the user guide: http://www.twowayradiosfor.com/pdf/RDX-Non-Display-manual.pdf
Instructions for setting the VOX sensitivity are on page 33.

According to the manual you program the VOX using the CPS (software). Three things which usually cause end-user problems are:
1) Failing to set the sensitivity to a number 1, 2, or 3.
2) Failing to have the radio shut off when plugging in the audio device (headset or earpiece)
3) Failing to use a VOX capable audio device. (Not all headsets and earpieces are VOX capable. Many with inline PTTs are not.)

If these items or instructions do not help, stop by your local Motorola dealer to discuss the problem.

VOX is the word used for voice activation.

The AX series did not have VOX capabilties. Here is a link to the Owners Manual for the Motorola AX series two-way radio.

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.
