Question about Motorola Walkie Talkie 2-Way Radio

1 Answer

Communicating between T5200 and Md203R

Have two T5200s which work fine together and two MD203Rs that work fine together. Would like all four to communicate. All on the same channel. the T5200 can transmit to the MD203Rs and they receive from the T5200, but can not talk from the MD203Rs to the T5200 (or maybe the T5200 can't receive?)..Please help. Thank you.

SOURCE: i have a problem


Normally in a Motorola T5700, to set a specific channel to monitor (and reply to) called your working channel, you press the Menu (center) button and the current channel shown in the display will flash. Press either the + or - buttons to change to your desired channel number which should be identical to both radios. Press the PTT button to save.

Likewise, both radios must have identical Interference Eliminator Code. To set code, press Menu till the code display blinks. Press + or - to select code. Press the PTT to save. To disable the code, select 0.

Hope that this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

SOURCE: talkabouts not communicating

What you have described is typical of the radios not being on the same frequency and/or code. If you know how to put your radios in programming mode, set all the frequencies and codes to the same number, then they will work together. If you still have the owners manual it will describe this process. Usually with a TalkAbout radio it consists of holding in the PTT while turning the radio on.
As you are probably aware, the radio will have approx. 14 frequencies installed. You can usually select these easily from the front panel. The second number you see in the corner of the screen when you turn on the radio is the "code". This is an interference eliminator. All of your radios need to be set to the same code to work correctly together. If you find one or more of your radios does not have "code", simply set those that have "code" to zero.

SOURCE: T5420 unable to transmit or receive. Please help!

Here is a link to the T5000-T5500 user manual. ''

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.

SOURCE: 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.

SOURCE: I have 2 Motorola T5000s and 1 T4500 that came

Here's a link to the user guides:

Check your interference eliminator code (aka PL, private line, or code). It is likely set to zero (off) on the T5000s and set to a different number on the T4500s. They must match to work together. Otherwise the one with code turned on will not recognize the other one.

Best regards.

Can T5200 communicate both ways with MD203R?

The easiest way to know is to set the Frequency, and interference eliminator Code to the same settings on each radio. Turn off any special features for your initial test. When set to the same settings the radios should work together fine. Then you can add back in any special features one at time until you have the radios set up the way you prefer.
Here are links to the user guides for each model. You can compare freq. charts and see how to program them:

Somewhere on the bottom of the mouse there is a small button, about the size of a ballpoint pen's ink tip. You need to push this in, and push in the corresponding nub on the wireless unit, until they work together. Once you have them in synch, the mouse should work just fine.

Make certain that your batteries - on both units - are brandy new and in full chagre.

Good luck.
