I have a set of Motorola T5720 walkie Talkies. I cannot determine if one of them is not receiving or the other is not transmitting.


One radio works properly, the other can receive. I assume there are more than two by the question. Check and then rotate you batteries, mark on the working unit battery that it is GOOD. Transmit takes a great deal more power than receiving. Batteries, even un-used only last 18-24 months typically. If no joy, then check your programming but I think that is unlikely. It really sounds like a power/battery issue.

My radio is not transmitting what could be wrong


When the batteries are reaching the end of their life or in need of charging the first thing that is likely to happen is that the unit will be weak when transmitting while receiving just fine. This is because it takes a lot more power from the batteries to transmit than to receive. Try a new set of batteries or if rechargeable then try charging the unit. With regard to regular batteries, make sure your batteries say "alkaline" on them somewhere since they will last much longer and also are more likely not to leak inside which can ruin your radio. Ignore labels on batteries that read "super heavy duty" or other such nonsense. Look for one and only one word "alkaline" on them and buy any brand you want to since cheap or expensive they are basically the same. Don't waste your money or risk your radio by using anything but alkaline batteries.

Hope this helps.

How long will my four aa batteries last in my walkie talkie


Typically you can expect the AA batteries to last about 18 hours using the 5-5-90 rule. (5% of the time your are transmitting, 5% receiving, and 90% standby) If you transmit/receive more than this the time the radio would go would be shorter.

Best regards.

Motorola Talkabout MR will not transmit


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.

Two motorola t8550's unable to communicate


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.

Does not receive FM signals anymore, just noise.


The T6310 is a disposable radio. Assuming the programming is correct, and matching on each of your radios, and you are using good batteries, there is nothing which can be done to correct the problem. We would however, suggest you double check your programming, and also the age of your batteries.

Sidenote: Rechargeable batteries only last 18-24 months before they begin to fail. Signs of failure can include, but are not limited to, poor transmit, intermittent transmit, white noise, squelching sounds. It takes more energy to transmit than to receive, so your transmit would be the first to go.

Won't transmit


First I would check the interference code on both radios to see if it is set the same. It is possible you have one set to zero and the other set to another number. This would cause the problem you describe. The interference eliminator is designed to block out transmissions from radios whose settings do not match it.

If all your settings are identical, and you have only 2 radios, it is not possible to tell which one has the problem. You either have one with no transmit or one with no receive. The only way to tell which you have is to get a 3rd radio involved, set to the same settings.

Motorola T5420 Transmit Problem


Here are some troubleshooting thoughts:

1. Is your battery indicator showing at least 2-3 bars? (Battery Note: Your rechargeable batteries may fail due to setting without use for a long period of time. They need replaced every 12-14 months usually. A good tip is to charge them once a month to keep the chemical in the battery active.)

2. Check to see your Qt noise filter is shut off. Refer to page 22 of the owners manual. It is possible you have some radios set to Y and others to N. To assure good communications you should set all of them to N.

3. With your radios set to interference code zero, place your radios one at a time in scan mode, while you transmit/talk on one individual radio. See if any of the radios receive. Do this with each radio individually to see if you are transmitting at all. NOTE: This test will determine if you have any ability to transmit. If you do not receive any sound on the 3 radios setting in scan mode, the individual radio you are testing will not transmit.

T5420 unable to transmit or receive. Please help!


Here is a link to the T5000-T5500 user manual. 'http://www.motorola.com/mdirect/manuals/T50-T55_UserGuide.pdf'

From what you have stated, I can discern the radios will power up. You might try setting your interference eliminators to zero (off) to see if you are able to transmit at all.

You do not mention if you are using AA batteries or rechargeables. Either way a fresh set of charged batteries would be best for a test. It is clear you were getting power. However, it does take more energy to transmit than to receive. If your batteries are low or bad, pressing the PTT could us all the energy the radio has, and yet not transmit to the other units.

You might also check you VOX settings if any and be certain they are turned off.

It is not likely 4 radios would fail all at the same time. So it is probably a programming problem. Hope the user manual helps you find the solution.

FR60 intermittent transmission


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,
Ken
