Connecting to the Phone Line
High Speed Internet
Once the handset battery pack is fully charged,
connect the telephone line cord to the TEL LINE jack
and to a standard telephone wall outlet.
If your phone line also has High Speed Internet
please ensure you are using an approved line filter
before connecting the telephone cord.
Connecting the Base and Charging the Handset
1. Connect the AC adapter to the DC IN 9V jack.
2. Connect the AC adapter to a wall outlet that is not
controlled by a switch.
3. Place the handset in the base with the LCD screen
facing forward.
4. Make sure that the charge LED illuminates. If the LED
does not illuminate, check to see that the AC
adapter is plugged in and the handset makes good
contact with the base charging contacts.

into the phone line.
Note: Use only the supplied AAD-041S adapter with your phone.
Do not use any other AC adapter.
