For the purpose for debugging your "NO Dial Tone" issue, please UNPLUG you cellphone charging cable first:
* If you hear "..warning, your cellphone is not connected..." and the RED LED is OFF, please click hereto start setup.
* If you hear "..warning, your cellphone is not connected.." and the RED LED is SOLID ON, please do a Factory Reset.
* If you hear "...pairing...." for few minutes and not connected, please click here to see detailed pairing procedure. * If your "No Dial Tone" issue ONLY HAPPENS when Cellphone charging cable PLUG IN, please press 60# from your home phone.
Note: After the call (cellphone hangup), the home phone will take 30 sec to couple mins to get "Dial Tone" back. If you don't want to wait, you can press Flash to get the "Dial Tone" back and dial for next call.
