Please tell me if I can register (and use)
an KX-TG7301 handset(or an KX-TG7302 handset)
as the 3th handset on a KX-TG7302 base.
In manual is recomended KX-TGA731AZ but I can't find it in our country.
Thank You !

I have logged many different dect models of panasonic cordless phones to different bases and never had a problem. it should work fine.
I have a kx-tg7301 cordless here and have logged it to an other model base with no problems

Thank You OBT !
