Welcome to AT&T
Welcome
Not compatible with home security systems, wireless messaging
and data services, fax service, DVR/Satellite systems, or medical alert
systems, credit card machines, IP/PBX Phone systems, dial-up or
DSL internet service. The Wireless Home Phone Base is designed to
provide coverage that is consistent with other AT&T wireless devices,
but AT&T does not represent that the Wireless Home Phone Base will
be the equivalent to landline phone service. 911 calls are routed based
on the wireless network’s automatic location technology, but you may
have to provide your home address to emergency responders. AT&T
recommends that you always have an alternative means of accessing
911 service from your home during a power or network outage, such as a
landline telephone.

How It Works
Wireless Home Phone Base uses the AT&T cellular network
to provide phone service to your corded or cordless home
phone(s). Place it anywhere in your house where you have a
wireless signal. It does not require the use of a home phone wall
jack like traditional home phone service.
Wireless Home Phone Prepaid service includes many calling
services, such as voicemail, Calling Number ID, Call Waiting,
Call Forwarding, and 3-way Calling for your corded or cordless
home phone(s). It also includes a back-up battery in case of
power outage.
Device Installation
Before You Begin
Make sure you activate your service as directed in the Quick
Start Guide before you begin device installation or attempt
to make a call. Wireless Home Phone Base works exclusively
with the AT&T cellular network and DOES NOT use your
home’s phone wall jacks.
Your device should
be located:
• Where you have a
strong cellular signal
from a cell tower,
typically near a window
or outside wall.
• Near an electrical
wall outlet.
Select which phone(s) you will use with the Wireless Home
Phone Base:
• You may connect up to two phones.
• If using an existing phone, unplug it from the wall jack.
Getting Started
Install the Back-up Battery
Remove the lid from the battery compartment.
Insert the battery connection cable into the battery port.
Place the back-up battery in the battery slot and replace
the battery cover.
During a power failure, the back-up battery enables voice
calling using a standard corded phone that does not
require external supplied power.
Notes:
• The back-up battery is intended for backup purposes
only and may take approximately five (5) hours to fully
charge.
• Charge time may be impacted by environmental factors
and the back-up battery will stop charging when the
ambient temperature is outside of the temperature
range allowed for charging (32 °F - 131 °F).
•
Remove the back-up battery if the device will be
disconnected from AC power for 15 days or more to avoid
possible damage.

Press and hold the round On/Off button for 2 seconds until
the signal strength light comes on.
Check the Wireless Signal
Raise antenna to an upright position.
Confirm signal strength light is green for optimal

may want to choose an alternate installation location.

machine by plugging it into the “Phone 2” port on the back of
your Wireless Home Phone Base.
