Question about Motorola T5710 (22 Channels) 2-Way Radio

1 Answer

T5710 Will Not xmit, etc.

1st: My batteries are good. Contact is good. One radio will come on sometime. Display looks good, and you can use the menu button. When you go to xmit, the display blinks and will not xmit. It will receive, but sounds scratchy. Sometime when you turn it on it takes a few seconds for the display to appear. Now it does not come on at all.

Any Help????

    Jerry are you sure that the battery charger is charging the battey. if not use a volt meter to check the battery and charger. If this is not the problem then I would consider taking the radio to a good service center or sending the radio to the factory.

I know you say your batteries are good. However, the symptoms you are describing would indicate a bad battery. Just to be sure, you might swap the batteries between the units and see if the problem moves with the battery. If not, you are correct, the batteries are good.
The next issue would be an internal radio issue, such as the unit has gotten wet or moist, and corrosion is beginning to form on the board. OR it is possible you have a hairline crack in the component board and this is causing some of the traces to make a poor connection.
FYI: It is common with these smaller types of radios for people to put them in their back pocket and sit on them. This will many times cause hairline cracks in the component board, or will cause small components to pop off the board.

Cannot set interference eliminator code on my second t5710


First check to see that your keypad is unlocked. You can lock/unlock the keypad by holding in the PTT button for three seconds. You will see a little lock icon when it is locked.

To set the code for a channel:

1. Press Menu until the CODE number begins to flash.

2. Press the + or - to select the desired code.

3. Press the PTT to save the code.

Note: You can set a different code ofr each channel using this procedure.

Zero (0) equals OFF.

If you continue to have problems, set both radios back to a very basic setting with all special featured turned off and see if you can communicate. Then add the desired features back in one at a time until you have what you'd like on both radios.

Best regards.

Submerged one t5710 unit crossing a river; no longer transmits.


Probably not.

The electronics in the transmit / recieve circuitry (RF = radio frequency) work very differntly from those in the display and control circuits, which prob ablyexplains why the display works, but not the rest.

The major problem with water in RF circuits is that even after it dries out, it leaves a residue, or worse still some corrosion, which adversly affects the tuning of the RF circuits.

It may be worth trying to dry it out a bit more - put it somewhere warm but not humid like near but not too close to a central heating boiler, for a few days. However, I suspect it is now beyond repair.

Hello bwilliam. Batteries can give you a false reading. Check your batteries under load. Good luck.
