As shown here, the Aplio/Phone's AC adapter plugs into a standard electrical outlet and into the DC IN connector in the back of the Aplio/Phone. Also, the Aplio/Phone connects between your telephone and a wall-jack.
If you want to connect an answering machine to your telephone, connect the telephone to the answering machine, connect the answering machine to the Aplio/Phone and connect the Aplio/Phone to the wall-jack.
Note: The installation process may vary from country to country.
To install the Aplio/Phone:
1. Locate the telephone cord that connects your telephone to the wall-jack. 2. Unplug the cord from the wall-jack, leaving the other end of the cord attached to the phone. 3. Plug the loose end of the cord into the jack marked PHONE on the back of the Aplio/Phone. 4. Plug one end of the cord that came in your package into the jack marked LINE on the back of the Aplio/Phone. 5. Plug the other end into the wall-jack. 6. Plug the AC adapter into an electrical outlet, then plug the other end of the AC adapter into the plug marked DC IN on the back of the Aplio/Phone.
When you have completed the installation, the 
button should illuminate
briefly, followed (in about ten seconds) by a series of beeps. After the beeps, pick up
your telephone receiver to check for a dial tone.
If you hear a dial tone, you can begin gathering your configuration information. Instructions appear in "Getting the Information You Need".
If you do not hear a dial tone, check to make sure that all cords are plugged in securely and that the AC adapter is plugged into a functional outlet.
