We have 4 KX-TGA401C handsets. Suddenly 3 of them are not working and display "Check tel line" message. I have checked the connections. Suggestions?

I agree with the below answers. The suggestion that you make sure they all have separate numbers, 1 through 4 is also correct. You can clear all the phones AND then place them on the master and get the numbers reassigned. Also if you are too far away from the master, it can say something like what you are reading....beyond that I cannot think of anything else...I still think that it is a reassignment of the numbers issues.

I would ask manufacturer, but I assume the working one is the one goes in master, so try putting others in that. Also be sure that each one has separate number, 1 thru 4. If one is working, tel line is OK, so it has to be the assignments.

Your main unit has a telephone wire that connects to the landline. If it becomes unplugged (for example, by accident), you will get this message. Simply plug it back in and all phones will work again.

By "checked the connections', do you mean you've taken each phone to an outlet and verified one by one that they are working? Suggest unplugging all of them at same time, resetting (clearing) all codes/settings, then one by one plugging them back in. Making sure each (one at a time) is recognized by the base unit.

If the base station phone is working, then I'd suggest unplugging the base station and putting it in another phone jack in the house. The only time I've gotten that display was when my FIOS line was accidentally cut. It just sounds like the base station isn't communicating with the handsets. I have two different cordless base stations in my house, and haven't had a problem, but that doesn't mean it couldn't happen.

I'd suggest you call Customer Service (if you are able to make calls) 1-800-332-5368 or try http://www.panasonic.com/help It could be something with your base phone and a possibility the others are not registered to it, or perhaps answering machine, if you have one on your base phone? Just a thought on these! I did call Customer Service once, and they were very helpful! Also - if you have other phones of a different maker, that could confuse your phones. Someone I knew had their phones all messed up and it was due to a Uniden phone. Once the Uniden was disconnected, other phones worked. I don't see anything in the manual on the base phone in "troubleshooting" relating to this, so perhaps a call is needed??

OK!........4 or All of mine are making sequel and crackling sounds when a phone call comes in. I was told to unplug the charger and let it set for 15 minutes and then plug them back in. They are still making large crackling sounds and squeals! Now what should I do because I purchase the 6 set through amazon. The one out in the shop I doubt is a problem so I'm not worried about #6! Up until last week everything was great. Now I'm having problems and I put in new rechargeable batteries but I still get the screeching and scratching noises! Bruce HartogWildwood, FL 34785

We have had our 3 handsets for over 5 years without a problem with any of the sets. I you still have the instruction manual, you might want to check the feature which allows you to block calls. We have never used that function and I do not have any idea how to activate or deactivate that feature. Are you able to receive calls from other land line phones still, and is it from all cell numbers, or just one specific number? Sorry that I cannot be of more help, but you might want to go to the Panasonic website and see if they may be of assistance. Loren

Check basics out: see if the handset is hung up, see if the phone line is securely in the phone jack and the back of the phone base, and see if any other phone you have is off the hook.. If you have a corded phone, plug it in and check your line for a dial tone. It can be a bad phone line or even that the battery has gone dead.

That's the same problem I had. The numbers on the keypad of the phone stopped working, prohibiting me from retrieving voice mail. I got rid of the V-tech phone and bought a Panasonic. Works much better and has a "call block" feature to prevent annoying telemarketers from calling!

All I can say is ditto to checking the phone cord(s) you are attaching are on an active line. Try plugging the cord into a phone you know works to test the cord. Good luck!

Can't help you. I bought the set with 3 handsets and then bought an extra handset to make four and they all work fine. Go the descriptions and model number.

The ones that I got plug into the wall KX-TGD220. I was having trouble with static and phone cutting off during a call. I plugged it into another phone jack and that helped a lot only cut me off 1X in the last few weeks and much clearer sound, so it had to be my jack and not the phones?

Yes! The KX-TGA660M is an Extra Handset for: KX-TG7644M, KX-TG7642M, KX-TG7645M, KX-TG7643M, KX-TG7622B, and KX-TG7623B systems. I purchased this same additional phone to add to my KX-TG7645M system and it works perfect. There is one thing to note: For some reason my KX-TGA660M screen is brighter/clearer than the rest of my other phones in the system and I purchased this phone new NOT refurbished. I just wish the rest of the phones had this screen! otherwise the phones are all identical in color and functionality.

I had a similar problem.. I took the battery completely out for a few minutes and then put it back in. Once I did this the phone linked back up. No problems since then. (I have 5 handsets - the one in the basement was the one that I lost the link)

The answers that I have provided for this handset have come from Google searches for the instruction manual. Do a search on the KX-TG7641 and you'll find out.

Whoops my bad. I think you need this handset. http://www.amazon.com/Panasonic-KX-TGA660M-Handset-Cordless-Metallic/dp/B004O6MOBY/ref=sr_1_1?s=electronics&ie=UTF8&qid=1397566409&sr=1-1&keywords=KX-TG7641+handset

Exchange it -- or call your telephone provider -- no problem with the 10 that I purchased and gave as Christmas gifts -- you probably have bad wiring from the phone to the telco. Try, first, changing out the simplistic (2-wire) rj-11 cable from the phone to the jack. If you can, and you have traditional telephony service, take the phone directly to your dmarc and try there.

I just bought these phones. Now I know why it chimes. I have another issue. I plug the phones and they work fine. Then for some reason when I receive a call you can't answer it. You push the "talk" button and it won't answer. If you take the battery out of the phone and put it back it works but only for a short time. It then goes right back to the same behavior. Looks like I should have read the reviews before buying.

I bought mine to add to a KX-TG7641 system. It matched those handsets exactly and was simple to register into the network. It appears to be the same as the handsets used in the KX-TG7644M and I would not hesitate to try it.

Don't know why, but, I ordered three phones and all are working fine. Warranty might have to do with the fact that they are set-up for the provider Telus in Canada and they are being sold in the USA.
