Re: will not re-charge handset

Try wiping the metal terminals with alcohol & cuetip. This should be done every 30 days or so.

Battery charged displaye no link to base

Many models of cordless phones that have multiple handsets require the handset to be cradled in the base unit for identification and link. As long as the handset maintains a charge, the identification remains valid. If you remove the battery or drain the handset to a point where the handset ID is lost, then you may have to re-cradle the handset in the base unit to reestablish link.

Handset 2 which is doc upstairs goes dead as soon as you want to use it

It's time for a replacement battery. Cordless telephone batteries can be purchased at most places that sell cordless telephones, or battery stores such as batteries plus.

A test for this is that you can swap the batteries with handset 1 and see if the problem follows the batteries.
Does it appear to be charging when on the cradle?
Attempt to charge Handset 2 on the charging cradle you have for Handset 1.

Good Luck,

New out of the box wont power on

Hi.. Let me try to help you if I can... I'd like you to check a few things,

1) Open battery cover on handset & make sure that the battery pack is installed correctly, and not upside down. Also make sure the little wires that come from battery pack are plugged into the tiny jacks of the phone (usualy red & black wires) in handset is fully attached & pushed snuggly into the handset... and if No wires, check to ensure the part that does connect the battery to handset is not covered with a plastic film of tape or paper as right from a manufacturer they sometimes do that to preserve length of battery until product is sold to you..

2) Check the bottom of the handset phone, that sit in the cradle of the electric part of the recharger, and make sure there is nothing like plastic or paper covering the connections between the bottom of the handset and the charger. Make sure there is a full on connection for a full charge to the handset. As with some cordelss phones Ive had the red LED light will not come on if there is something blocking a full connection for a charge.. The red LED light on base, only comes on when the electricity is flowing into the handset. The slightest tilt not allowing handset a full charge, wont give it a FULL charge.

3) You say " NEW. Out Of The Box" I hope when you connected the battery pack into the handset, and made sure it was connected right, you then allowed handset to charge at least a FULL 12 -24 hours before trying to use your new cordless phone. as the batteries right out of the box, are rarely already fully charged when any cordless phone is bought and then it does need 12 - 24 hours for a FIRST FULL CHARGE...

If you can check all 3 of these questions, and let me know how things are back on this posting, if you stilll can not solve the problem after a full charge to battery, I may have some other ideas that can help.

Good Luck

Phones are powered but do not connect to base so can't receive or make calls. Is there a way to reset?

The manual, which can be found at:, reads:
4. Place the handset in the base cradle. The charge/in use indicator turns on,
verifying the battery is charging. The unit will take 20 seconds to register
and verify its security code. READY shows in the display.
NOTE: In case of a power failure, the handsets may display
UNAVAILABLE when the TALK/CALL BACK button is pressed.
You must then place all handsets on the main base cradle
for 20 seconds to re-register.
That should reset your handsets. Hope this helps :) Thank you very much.

I have a Panasonic KX-TG6051CM

I had the same problem, and it seems that the battery charging circuit in the handset had locked up, constantly charging the battery until it overheated. I was able to reset the circuit in my handset by completely draining the battery. Here is the procedure:

1. Remove the handset from the charging cradle, and leave it on for a few days until the battery runs out, and the handset finally turns off. At his point, the battery will be very low, BUT NOT COMPLETELY DRAINED.

2. Next, you must manually drain the charge remaining in the battery by shorting out the two contacts on it. Shorting won't damage the battery, since it is holding very little charge at this point. An easy way to physically do this is to remove the battery, and place a piece of thin wire across the the two contacts of the HANDSET. I am referring to the contacts inside the handset that connect to the battery, NOT the contacts on the bottom outside that connect the handset to the charging cradle. Next, put the battery back in, sandwiching the wire between the battery's contacts and those inside the handset. This will hold the wire in place. DO NOT PUT THE HANDSET BACK INTO THE CHARGER, WITH THE BATTERY SHORTED OUT.

3. Wait about 30 minutes for the battery to completely die. Remove the jumper wire, and but the handset back into the charger.

4. If the battery was fully discharged , you will get a message on the handset telling you that you should let it will charge for 7 hours. If you do not get this message, then either the battery was not fully discharged, or your problem is different from mine. Try the procedure again in Step 3 for another 30 minutes to discharge the battery some more.

5. If you get the "Wait for 7 hours to charge" message on the handset, then leave it in the charging cradle for the 7 hours requested. After that, it should work fine.

Let me know how you make out.

ELBT595 Handset Not Turning On

Check the handset battery -- if there is a slight "bulge" on one side (ie: not COMPLETELY flat) then the problem is with the battery. I had that problem and had to order a new one. That said, I just installed the new battery, and while it now charges, the handset won't connect to the base unit. The base unit works (tried the speakerphone), but there is not connection between base and handset.

My handset won't charge

Try charging it in a different cradle if you have more than one handset.  This has happened to me where a particular base will not charge a particular phone.  Once charged elsewhere the problem resolved.
