Need to clear out a used kx-tga270s handset

http://service.us.panasonic.com/OPERMANPDF/KXTGA270S.PDF

There is a section on setting the number of rings in the manual for the base unit on page 28. You can download it from here: http://www2.panasonic.com/consumer-electronics/support/Phones-Fax/Telephones/Expandable-Systems/model.KX-TG2740S

It probably needs a new battery.

IT IS DUE TO FAILURE OF ANTEENA

IT IS DUE TO NETWORK FAILURE OF THAT LINE

Above is link to Operation Manual. See page 65

For Panasonic system (especially for KX-T7633), you have to make changes from extension 101.
1. leave handset in the cradle then press "program".
2. Dial *# then "SP-PHONE" button until you see something like time set something something
3. manually input correct date then time then press "auto dial/store" button.
4. pick up the handset then hang up to save.

IF it was a used handset it was likely registered to another base. I just switched bases (1line to a 2 line base). I had to "deregister" the handsets from the old base. I am not sure if you can deregister if the old base is not present? With the old base plugged into power I hit the "function key" at the bottom left of the handset and scrolled down to initial settings. Under registration is "deregistration". I selected that and it put the handset back to its default out of the box. Then simply hit the mute button on the New base and OK on the handset. Worked for all 5 of my old handsets.

Hope this helps

Real easy... remove the battery and you'll see 2 screws. then start peeling the phone in half from where the screws were.. the phone may seem like its breaking but it does snap apart... then you will needs a soldering iron to replace the antenna..
