Hello! Please perform the following steps to determine the root cause of the error message:

1. The supplied telephone line cord has not been connected yet or not connected properly. Check the connections by making sure the line cord is secure. When you plug the telephone line cord at the back of the phone make sure you hear it click.
2. Plug the telephone into a different telephone line jack inside your house. This is a test to see if it is a problem with the telephone or a problem with the telephone jack. If the telephone operates on a different jack then the problem is with the original telephone jack.
3. If the telephone does not work on either telephone jack you need to determine if it is a problem with the telephone or the telephone line. If you have a different telephone, plug that telephone into the telephone line jack and see if you can hear a dial tone. If there is no dial tone you are having a telephone line problem, contact your telephone line service provider.
4. If you do not have a different telephone to test, take the telephone to a neighbor or friends house and test, if the telephone operates on a different telephone line then the problem is with the telephone line. 
After testing if you determine it is a telephone line problem, contact your telephone line service provider. 
If you are using this model on a digital phone line (office, business line) it may not work. This is a consumer home use telephone that is not compatible to business telephone systems. 
For models with the Link to Cell feature - If you do not connect the telephone line cord and use only cellular lines, set the cellular line mode to Cell line only.
