This article describes how to attach your home phone to the Home Base.
INSTRUCTIONS & INFO
To place phones throughout your home, you should use a cordless phone system with multiple handsets. A standard corded phone can be used if you just need one phone in your home. Note: The Home Base does not use your home inside wiring. You should not plug the Home Base or your phone into your home phone wall jacks.
Unplug the phone you would like to connect to the the Home Base from its wall jack.
Plug the phone into the Phone 1 port on the back of the Home Base, using your existing phone cable or the provided phone cable.
Note: If using a cordless phone, keep it plugged into an electrical wall outlet. Do not plug the Home Base into a phone wall jack.
An additional phone or answering machine can be connected to the Phone 2 Port. However, the phone will share the same line and phone number as Phone 1.
