I have two identical radios that were purchased as a pair. Both are using rechargeable battery packs that came with them and are fully charged. Both have all settings identical - Channel 1, Code 1 ( i have also tried 0), call tone 1, iVox off, Vox 2,Qt Off B5 0, Vibrate off, Keypad tone on, talk confirmation tone on. I can transmit from Radio A and receive it fine on Radio B. But, the transmission from Radio B does not do anything on Radio A. This is the same result for a PTT transmission or for a Call Tone. do I have one of the setting above set incorrectly? Thanks!
From reading through your settings, they appear to be identical. Except, I am not certain what Vox 2 is, or B5 0. If the number 2 beside VOX is a setting, you should set it to off or zero. Otherwise, they appear like they should work. (VOX = voice activation, and when enabled will cause a radio to transmit when it hears a sound, voice, etc.)
If you are using an audio device such as an earpiece or headset, be certain you are plugging it in with the radio turned OFF.
Lack of transmit can also be a sign of a bad battery or bad battery connection. You might try swapping the batteries and see if the problem moves to the other radio.
If these are less than one year old, use the number in your user guide to contact Motorola for a possible warranty replacement.
Best regards.

Hello snorker,
It could be battery / power issue. Two-way radios draw much more power when transmitting then receiving. If the batteries are weak the radio might work perfectly fine on receive and then cut-out when you depress the Push-To-Talk.
Best Regards,

SOURCE: Motorola Talkabout 5700, 60 second timeout?
The 60 second timeout is a feature which is necessary to keep from burning up the final amplifier in the unit. It keeps the user from ruining their radio. Most radios, including business radios have this feature. Continually holding down the PTT will also run the battery down very quickly.
It would be best to try getting a regular baby monitor.

One further thing to check would be the Qt filter.
If the frequency, code and Qt filter are all set alike, and the radios still do not function together, you likely have a defective radio. The only way to determine if one is bad is to introduce a 3rd radio into the group, and the bad radio will be apparent right away.
Best regards.

1) You did not mention the Qt filter. You might check to see if you have the Qt filter set the same on both radios. This is an additional layer of privacy featured on this radio.
2) Verify you have good working batteries. A bad battery or uncharged battery can cause a no transmit situation.
3) If these do not work, reset your radio back to a basic operation by shutting of the code, Qt filter, call tone, weather alert, Vox/iVox, roger beep, etc. At this point your radio would be operating just on a simple frequency. See if you can communicate with all these special features turned off. If so, slowly add back in the features you desire.
4) If your radios still fails to work and is less than one year old, call the 800 number on the pamphlet, have your serial numbers and radios handy. Your radio if not physically or water damaged is possibly still under warranty.
Most of the time when a set of radios has your problem description, it is the Qt filter, or possible improper use of a special feature such as call tones or iVox. These would be the first things to check.
Best regards.
