AT&T Wireless Home Phone Base

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 Base provides many calling services, such as
voicemail, Caller 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
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.

5Getting 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.
Connect the Power Cord
Insert the small end of the power cord into the Power Input
port on the back of your Wireless Home Phone Base.
Plug the power cord into an electrical wall outlet that is not
controlled by a wall switch.

6
Check the Wireless Signal
Raise antenna to an upright position.
Confirm signal strength light is green for optimal performance.
Yellow indicates a moderate signal and may be sufficient.
Note: If you do not see a green light (strong signal), you may
want to choose an alternate installation location.

Home Phone Base.
Then, set your answering machine to pick up calls in fewer rings
than the voicemail service, which is set to five (5) rings as a default.

the volume of the Wireless Home Phone Base can be adjusted if
necessary. While on a call, press ** or ## to enter Volume Setting
Mode. Press *to decrease volume. Press #to increase volume.

function that is independent of the Wireless Home Phone Base.

Important Information
Important Information
E911 Service
911 services are supported just as they are on any wireless device.
You should expect to provide your home address to the emergency
response center responsible for sending first responders (e.g.,
police, medical assistance, or fire) to your location.
Power Outages
Wireless Home Phone Base has a back-up battery with talk time
of up to three and a half (3.5) hours depending on environmental
factors. Please note you’ll need a standard corded phone that
doesn’t require external power to function with the back-up battery
for all calling, including 911.
Device Compatibility
Wireless Home Phone Base does not support your home security
systems, fax machines, dial-up or DSL internet service, DVR
services, medical alert services (e.g., Life Alert), or credit card
machines. The service cannot be used to make 500, 700, 900, 976,
0+ collect, operator assisted, or dial-around calls (e.g., 1010-XXXX).
The device does not support data services (e.g., texting, multimedia
message services (MMS), and data tethering).
In-Home Wiring
Interconnecting to home telephone wiring is not necessary, but
is possible; however, it is not recommended unless you possess
sufficient knowledge of electrical systems. Use with home wiring
requires the physical disconnection from other services, including
the landline coming into your home. Use of a qualified licensed
electrician is highly recommended. Improper installation may
result in phone equipment damage or even a fire.
