How It Works
The AT&T Home Base uses the AT&T cellular network to provide phone service to
your cordless and corded home phone(s) and Internet access to your computer
and Wi-Fi enabled devices. Place it anywhere in your home where you have a
strong wireless signal. It does not require the use of a home phone wall jack like
traditional home phone service.
The AT&T Home Base provides many calling services, such as voicemail, Caller
Number ID, Call Waiting, Call Forwarding, and 3-way Calling for your home
phone(s). It also includes a back-up battery in case of a power outage.
Device Installation
Before You Begin
The AT&T Home Base works exclusively with the AT&T cellular network and DOES
NOT use your home phone wall jacks.
Your device should be located:
• Where you have a strong signal from a cell
tower, typically near a window or outside
wall. Signal strength may vary in different
parts of your home.
• Near an electrical wall outlet.
• In the general area where you’ll be using
your home phone, computer, or Wi-Fi enabled devices.
Select which phone and computer/Wi-Fi enabled device you will use with the
AT&T Home Base:
• A cordless phone system with multiple handsets should be used to place
phones throughout your home.
• If using an existing phone, unplug it from the wall jack.
• For Internet access, you may connect up to 10 devices via Wi-Fi and one
via Ethernet simultaneously.
4 Getting Started
STEP 1: Set Up Your Device
Install the Back-up Battery
1. Remove the bottom of the device by pushing the entire cover
in the direction of the arrow.
Ports
2. Insert the back-up battery.

3. Replace the cover.
NOTES:
• The back-up battery is intended for backup purposes only and may take
approximately eighteen (18) 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).

Using Your Device 21

Important Information
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.
Important Information 23
22
E911 Service
For emergency calls, you may have to provide your location address to the 911
operator.
Power Outages
The AT&T Home Base has a back-up battery in the event of a power outage, with
talk time of up to 100 minutes depending on environmental factors. However,
a landline phone requiring separate electric power to operate (e.g., cordless
phones) connected to a Home Base will not place or receive calls (including 911
calls) during a power outage.
The AT&T Home Base will disable Wi-Fi to conserve power while using the back-
up battery when there are no devices connected. To re-enable Wi-Fi while using
the back-up battery, press the On/Off button for one (1) second. Or, if power is
available, plug the AT&T Home Base into an electrical wall outlet.
If you experience a power outage and your battery is fully depleted, it will be
necessary to restart your device when power is restored by pressing and holding
the On/Off button for three (3) seconds until the power light stays steady green.
Device Compatibility
The AT&T Home Base is not compatible with wireless messaging services, home
security systems, fax service, medical alert systems, medical monitoring systems,
credit card machines, IP/PBX Phone systems, or dial-up Internet service. May not
be compatible with your DVR/Satellite systems; please check with your provider.
DSL customers should contact their provider before transferring a phone number
to ensure uninterrupted DSL Internet service.
The AT&T Home Base cannot be used to make 500, 700, 900, 976, 0+ collect,
operator-assisted, or dial-around calls (e.g. 1010-XXXX).
Important Information

Frequently Asked Questions
What kind of phone do I need to work with the AT&T Home Base?
Most standard touch-tone phones may be used. Rotary phones are not
supported. Expandable cordless phone systems provide the most flexibility and
allow you to easily place additional handsets throughout your home. Cordless
phone systems still need to be plugged into a power outlet. A standard corded
phone can be used if you just need one phone in your home.
During a power outage, a standard corded phone which doesn’t require electrical
power is required.
How do I install my AT&T Home Base?
Refer to pages 4-10 of this guide for the most common installation methods.
Other helpful information:
• Installation near a window or outside wall is strongly recommended to ensure the
strongest possible wireless signal in order to maximize voice/data performance.
• If the AT&T Home Base signal strength indicator does not display high signal
strength (Green) or voice/data performance is unacceptable, you may need to
relocate the device to another part of the home with a stronger wireless signal.
Will my AT&T Home Base work in areas with no or low wireless signal strength?
A strong wireless signal (Green) is recommended for optimal performance.
A moderate signal (Yellow) may be sufficient. If you do not see a green light, you
may want to choose an alternate location.
Does the AT&T Home Base support both voice and data?
Yes, you can use your AT&T Home Base for both voice and data, as long as you
subscribe to AT&T Wireless Home Phone and Wireless Home Internet plans for
the Home Base.
24 Frequently Asked Questions
Why don’t I see the name of the caller on caller ID?
The AT&T Home Base only supports calling number identification. However, contact
names stored on your home phone may display for incoming calls.
Can I move my AT&T Home Base and use it in another location?
Yes, your device can be moved to another location; however, your device should
be used in a location where AT&T is authorized to provide wireless service. If your
device is used while on other carrier networks, AT&T’s off-net usage restrictions
apply.Please see section 4.5 of your Wireless Customer Agreement for details.
When I dial a seven-digit number using the AT&T Home Base, I get a message
that the number cannot be completed as dialed. Does the AT&T Home Base
support seven-digit dialing?
The AT&T Home Base requires 10-digit dialing for domestic calls in most areas.
