Hello. My name is***** am sorry that happened to you. Unfortunately, it does not appear that the KX-TGEA20 handsets will be compatible with the KX-TGD220 base unit.
According to the user manual for the Panasonic KX-TGEA20 handset, this unit is an additional handset compatible with the following series of Panasonic Digital Cordless Phones:
- KX-TGE210/KX-TGE230/KX-TGE240/KX-TGE260/KX-TGE270 (KX-TGEA20)- KX-TGH260 (KX-TGHA20)
(The corresponding models are subject to change without notice.)
Please note that the KX-TGD200 is not listed as compatible.
I am providing links to the user manual for both the KX-TGEA20 handset (http://phone.manualsonline.com/manuals/mfg/panasonic/kxtgea20.html)
and the KX-TGD220 base unit - ( ftp://ftp.panasonic.com/telephone/om/kx-tgd210_mul_om.pdf)
in case you would like to look them over. I am confident that you will come to the same conclusion that I did.
