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

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.)

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

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

Best regards.

I would suggest taking the radios back to a very basic programming with the interference eliminator set to zero or off, and any special features shut off. This would enclude Qt filter, call tones, iVox/Vox, vibra call, keypad tones, roger beep, enhanced scan, weather, etc. Set both radios to the same frequency and see if they work. If not, try switching the rechargeable battery from one radio to the other. Does the problem move to the other radio? If so, you need a battery. If neither of these helps, you likely need to replace the radio.

The Motorola talkabout SX700 2-Way Radio is capable of operating on GMRS/FRS bands.
Here are the Family Radio Service and General Mobile Radio Service frequencies: http://en.wikipedia.org/wiki/General_Mobile_Radio_Service#Frequency_chart http://en.wikipedia.org/wiki/Family_Radio_Service#List_of_FRS_channels

Only plug the headset in with the radio turned off, and be certain to use a headset designed for the radio. On the SX model radios the VOX or iVOX feature is automatically set to the last sensitivity setting when you plug in an audio device. Here is a link to the user guide, where you can read how to turn iVOX and/or VOX on or off.

It is likely the mic set you are using is not made for the SX700 radio, and is drawing too much power from the radio. Some audio accessories draw more power than others. It is possible your mic set is intended for a professional model radio which would supply more power to the device. You should check with Motorola to see if they have a mic set similar to go with your SX700 radio. Here is a link to their online store: http://www.store.motorola.com/mot/en/US/adirect/motorola;jsessionid=130652F39955D9E9CA94908C45C73822.mot3?cmd=catDisplayStyle&entryPoint=adirect&catKey=601560&messageType=catDisplayStyle

Here are a few troubleshooting ideas. 1) Check your battery installation, and clean the contacts both of the radio and battery with a pencil eraser. 2) Install fresh batteries (or swap the rechargeable from your other unit) to see if it is a battery related issue. Static is a sign of a bad or low battery. 3) Turn your CODE on to a setting and continue using the radios as normal with a CODE to block the noise. It is possible due to dropage the radio may be more sensitive to RF in your enviroment than the other radio now. It could have a possible hairline crack in the componet board, or a cracked/damaged speaker.

you miss to save your last program,after you turn to vox mode you must to save ,or the mode will back to before you change

Try contacting http://www.ewingenter.com/accessories.htm They have one listed for $13 US.

Check your "code" setting. You may be on the same channel, but different codes. The code is the smaller number. Check your owners manual if you have one for resetting the radio to the factory default settings. This will clear any programming issues.

The wire to headsets can get damaged (usually not visible from the outside, as the wires inside the covering can be very delicate, to keep the size of the wire down) from throwing them in the pocket, purse, etc. Try a set from a friend to make sure the device is still working itself.
