Active headset


Your headset is operating in VOX mode. This sometimes will happen if the headset is plugged into the radio when the radio is still turned on. Try unplugging the headset, turn on the radio, then talk using the PTT on the radio. Shut the radio back off. Then insert your headset plug, being certain it is seated (click) into place. Then turn the radio back on and see if it works without VOX. If you are still having problems, press the PTT on the radio one more time and see if it shuts it off.

Issue using headset with motorola talkabout md200


You may have one of the following issues:
1) Defective headset or non-compatible headset. Try the headset on the other radio to see if you experience the same problem.
2) Headset is not plugged in all the way, until you feel a click.
3) Your radio's jack is wobbled out, or defective. Try moving the plug in or out slightly in the jack to see if you can find a sweet spot. Jacks can be worn due to plugging and unplugging chargers or audio devices repeatedly.

Tips:
1) Just as you have been doing, make certain the radios are turned off before plugging in any audio device.
2) Once you plug in the device and turn on the radio, press the PTT button once to initialize the PTT capability.
3) If you continue to have difficulties, reprogram the radios back to a basic operation, shutting off any special features such as call tones, Qt filtering, interference eliminators, weather radio capabilities, etc. Sometimes going back to this basic mode will alleviate the problem. Then one by one you can add back in the features you desire.

Hope some of this helps. Best regards.

Motorola talkabout MR350 headset only sends audio and can not recieve


Likely not compatible. One thing to try is to make certain the transmitting unit is turned OFF when you initially plug in the headset. Sometimes if a headset is plugged into a radio when it is already ON, the headset will appear to be in VOX (voice activated) mode and will not allow the user to receive. Also, if this headset has an inline PTT, it may not be compatible with the radio and you would need to use the PTT on the radio.

If this doesn't work, you would need to use the TalkAbout headset designed for the MR350.

Best regards.

Hi I have the T5622 talkabout with a PTT headset. I can transmit OK but I am not receiving anything other than a ''click'' when the other person transmits. I have tested the headset and I am able to recive...


Here a few thoughts which come to mind.
1. You do not mention whether the radios communicate with the headset no on the radio. I will at this point, assume they do.
2. Be certain to have the radio SHUT OFF when plugging in the audio device.
3. Check your VOX settings. It could be your radio is going into VOX mode.
4. Only use the PTT button on the headset. Do not press the PTT on the radio at any time while using the headset.
5. Check that you have CALL TONES shut off.
6. Lastly, if nothing else works, go back to a basic mode, and set both radios where there are no special features turned on. ie turn off CODE, Qt Filter, VOX, Call Tones, etc.

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.

Try a hand mic with the set, there may be a short within the radio.If not your problem is with the audio amp in the radio itself.Repair should be about $15.00.

My T5530 don't transmit audio to another radio, you can hear the.


good am, if no audio, try to check the microphone if its ok? , if not, just change, if its ok, try the PTT maybe the switch is busted or need cleaning, most cases is the need to clean due to dust and moisture. just spray contact cleaning fluid. - DU7UV

Headset transmits wave


If you are hearing it on the speakers then it is possible the other computer's problem. If you are hearing it though the headset it could be a headset problem. Check your settings and try talking to a bunch of other people to assess the situation.
