Hello & Welcome to Just Answer,Sorry I didn't see your question earlier and to hear of the trouble you are having with this additional handset.May I ask:1) is this a NEW handset, or was it purchased as "used" (or refurbished)?2) what is the Model of the MAIN BASE UNIT of the system you are trying to connect this handset to?3) how many TOTAL handsets do you have connected with the Main Base Unit now?Thanks
1) The additional handset has been bought new.
2) Main Base Unit Model No KX-TGA806.
2) One handset on the Main Base Unit, plus one additional handset which works OK, then this one.
The Base Unit four digit Number is *****
2) "No link to base, reconnect main base AC adaptor"
