Vtech DECT 6.0 Digital Cordless Phone - Page 7 Questions & Answers
My vtech dect 6.0 phone says not registered how do
I came on here to look for the same solution but it didn't take my comment and so I am sharing what I did from my research, If it says Not registered, press and hold the page button on the base and in about 4 seconds the In Use button will be lit. Release the page button and press the # button. You may have to try this a few times. The first time I tried it, it said Failed. I took the battery out, unplugged the phone from the wall and started all over again. Good luck.
Speakerphone
Nothing to "set up", just push the button with the little speaker symbol on it when you want to turn on speaker phone use.
Cs6648 not on site
Are you sure you have the correct model number? VTech doesn't list a 6648 on their site either.
DELETE A PHONE NUMBER FROM THE DIRECTORY
When you enter a number/letter, the "Mute" button serves as a backspace/delete function. So what I did was go to Menu>Directory>Review, scroll to the contact I wanted to delete, and press "Mute", which asks me to confirm to delete the contact. Hope this helps.
