Question about Motorola T-7400R GMRS/FRS 2-Way Radio Walkie Talkie with 7 mile Range

1 Answer

I have quit a few talkabout T7400 we bought a few years ago. None of them are working. I can tell you that they were being put back in the chargers in the on position. Is there a way I can test the batteries to see if they are chargeable, is there a way I can test the chargers to see if they are working? The little red light on the AC adapter no longer comes on.

To answer your questions:
1) The light on the charger should come on and stay on, when a radio or a battery is charging. It is not likely all the chargers would go bad at the same time. With this in mind, check your charge contacts on ther radio and the charger. Clean with a pencil eraser if needed. Try charging a battery outside of the radio (if you have a drop-in base), just to see if you get a constant red light on the charger. If not, your charger or possibly the battery is bad.
2) If you have a voltmeter you can check for existing charge in the battery. It will not tell you charging capacity, but it will tell you if it is flat dead or not. Check the date code on the battery. It is a 4-digit number on the back portion of the label in the white area. It will read as 1121, 11 is the year, 21 the week of the year. NiMH batteries have a 2 year life expectancy. And as you indicated, charging with the radio turned on, will age the batteries quickly. It is not good to leave the batteries on a charger with the radio turned on, or for extended periods of time, such as weeks or months. A few days won't hurt occasionally.
3) Lastly, your radios may need serviced. You could have charge/accessory jacks which are worn out, if you are using the wall plug style charger only, and do not have a drop-in base. If they have been anywhere moist they could have grown corrosion and be non-repairable. However, if they are dry and otherwise free of defect they should be repairable. (Current expected flat rate repair is $69 at a dealer who works on this model.)

Best regards

have you tried updating the firmware on the DS? It maybe because of that , that it wont play newer games? You will need to connect the DS via wifi to your home network the same way your laptop etc connects to it and then go into the DS settings menu and choose system update. Make sure the DS is fully charged and connected to a mains charger BEFORE updating. See if that solves your problem for you

You did not mention if the display comes on and they look functional, yet do not work. If the radio actually powers up. We will go from the idea the radio powers up and present a few troubleshooting ideas:

1) Clean your battery contacts. Use a pencil eraser and clean the contacts both in the radio and on the battery. If you are using a Motorola rechargeable battery pack, you should also clean the battery contacts on the charger. (Note: rechargeable NiMH and Li-Ion batteries have a 14-18 month life expectancy. Signs of a bad battery include: no or intermittent transmit, the radio shutting off when the PTT is depressed, lots of static when receiving, and/or erratic display.)

2) Set your interference code eliminator (code) back to zero (off), and do the same with your Qt filter if you radio is equipped with one. This will put you back to a very basic operation.

3) Check your VOX or iVOX settings, be certain these are also turned off.

4) Check your accessory jack to see if something is plugged into the hole. Remove any and all accessories to try in a basic form of operation.

5) Moisture is the enemy. Be certain radios are not stored near air conditioners, humidifiers, etc.

If the above items do not solve the problem, you likely will need to retire the units. As for your next venture. If you go with the Motorola TalkAbout line, examine your radios before the one year mark, save the receipt, most have a one year warranty. If you are wanting an all around better radio, look at the Commerical line of radios offered by Motorola, ie. CP110 and BPR40. They would offer a better durability and are designed to do a 40 hour work week.

Best regards.

How to charge battery in Motorola Talkabout Distance DPS


You can obtain a wall adapter style charger for your radio at your local Motorola dealer, or online at http://www.eradiostore.com/cart/index.php?target=products&mode=search&subcats=Y&type=extended&avail=Y&pshort=Y&pfull=Y&pname=Y&epcode=Y&q=htn8232

Sidenote: The rechargeable battery is good for about 2 to 3 years. You can tell the age of your battery by looking at the date code on the back of the battery above the stop sign. The first number is the year, the next two numbers are the week of the year. 915 would be 2009 the 15th week. (Or if very old it could be 1999 the 15th week.) A good battery, when charged will go an 8-10 hour day.

Keep both of your charge trays, replacements for these are no longer available.

Motorola TalkAbout Radio T74000 REPAIR


It depends on how long ago the water damage happened, on whether it will be repairable or not. If it was fairly recent, and you feel you got it pretty well dried out, then it is possibly repairable. If it has been more than 10 days or you left it wet, it is probably ruined from corrosion growth. If caught early corrosion can be kept to a minimum.

Get your radio to the service center of you choice right away to find out if it is repairable. If you do not have a repair center you can look us up on the web by our username.
