I have a 820 BELL SOUTH cordless house phone,,the base unit is operating because it is the digital answering system and the buttons are functional. I had explained to the other GURU that it is the hand set that the key pads are not operating,,,i am not getting a dial tone nor are the number button pads making any tone. I exchanged all the batteries and they are fully charged. The other guy stated to hold the page button down and unplug the ac cord,,,then replug the unit and the keypads should operate,,,he said,,,it did not work. was i only allowed 1 non-working solution per 12 dollars or can you still help me ????

SOURCE: Handset No Link To Base error and no dial tone

My battery is a Ni-Cd. I bought it new on eBay (TL26554 battery number). I allowed the new battery to charge for a long time and then tried to see if it would work. But no go....the handset gave me the same error message. Good Luck to you too! Mmmmmm

SOURCE: handset has No link to base

I was having the same problem with the same model phone, and fixed the problem by rebooting the phone – unplugging the AC and phone cord from the base station and plugging both back it, then removing and replacing the handset to regenerate the security code.

the links tat r there inside the phone are shorted as they r very thin threads like..just go to a repairer and he will resoulder the links and the problem will be solved..for temporary work just open the phone and remove all dust ..mostly keypad will start working

SOURCE: Handset ?No Link To Base? error and no dial tone

2/29 Have you registered or re-registered the handset?
"No link" can mean handset is not accepting radio wave of base unit. At Mfgr website pull-down operator's manual and look for registration instructions. Some sequence of buttons will create a radio signal from base (have handset off base) then another sequence of buttons on handset will accept radio signal. If handset has "menu" button, try "menu", then "00" (zero zero) then select an accept or "OK" button. Good luck.

SOURCE: No dial tone on handset

It may not be registed with the main unit. You may need to register the handset. With my uniden all i have to do is put it in the main base until it says what handset it is (it should be a number).

If you have any questions please dont hesitate to ask
