How It Works
The AT&T Home Base uses the AT&T cellular network to provide phone service to your cordless or
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 Three-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.
8
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 20 devices via Wi-Fi and one via Ethernet
simultaneously.
STEP 1: Set Up Your Device
○
A Install the Back-up Battery and the nano-SIM Card(Optional)
1. Remove the bottom of the device by pushing the entire cover in the direction of the arrow.
2. Install the nano-SIM card (Optional).
9
WARNING!
Your device only supports a nano-SIM card.
To avoid damaging the device, please only use the card that is provided by AT&T and ensure that
the nano-SIM card contacts are facing up when inserting it into the nano-SIM slot.
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 (0°C - 45°F).

Helpful Tips
Home Answering Machines
If you choose to use your home answering machine instead of the voicemail provided by your AT&T
Home Base, you will need to set your answering machine to pick up calls before network voicemail,
which is fewer than four (4) rings. If you have a standalone answering machine, you can connect it to the
"Phone 2" port on the back of your AT&T Home Base.
Alternatively, you can call AT&T Customer Service at 1-800-331-0500 to turn off the network voicemail
feature.
Adjusting Volume
Use your home phone's volume adjustment if available. Alternatively, the volume of the AT&T Home
Base can be adjusted. Six volume levels are available (level 1 to level 6) with the default setting at level 3.
While on a call, press ** to decrease volume or press ## to increase volume. Each time ** or ## is
pressed, the volume level is decreased or increased one volume level. To exit Volume Setting Mode,
press any other key or wait five (5) seconds.
Powering On/Off
The ON/OFF button is used to turn your AT&T Home Base on or off. When powered off, the AT&T Home
Base will no longer send or receive calls, but it will continue to charge the back-up battery if still
connected to the wall outlet.
To turn on your AT&T Home Base, slide the ON/OFF button to the ON position until the power light stays
solid green, if connected to a power supply (it will blink green if on back-up battery). To turn off your
20
AT&T Home Base, slide the ON/OFF button to the OFF position until all the lights turn off.
TTY Support
TTY (Text Telephony) and TDD (Telecommunications Device for the Deaf) are supported by the AT&T
Home Base. In order to use the TTY network, you must have a TTY-compatible phone and be in TTY
mode. Note that most digital wireless devices are TTY-compatible.
Dial *983*889*n# to set the TTY mode.
n = 0: TTY off mode. The standard voice speaking mode and listening mode. This is the default
setting.
n = 1: TTY full mode. Transmit and receive the TTY characters.
n = 2: VCO mode. Receive TTY characters but transmit by speaking into the speaker.
n = 3: HCO mode. Transmit TTY characters but receive by listening to the receiver.
Important Information
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
approximately 100 minutes and standby time of approximately 18 hours depending on environmental
factors. In the event of a power outage (commercial power no longer being available), the AT&T Home
Base will automatically begin using the back-up battery, provided there is sufficient battery charge left. If
there is no battery charge at the time of the power outage, the device will not be operable.
To make calls using your back-up battery, you must plug a corded phone or landline phone into the
"Phone 1" or "Phone 2" port on the AT&T Home Base.
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, slide the ON/OFF button
to the ON position. Or, if power is available, plug the AT&T Home Base into an electrical wall outlet.
If you experience a power outage and your back-up battery is fully depleted, it will be necessary to restart
your device when power is restored by sliding the ON/OFF button to the ON position until the power light
stays solid green.
Back-up Battery
A new back-up battery should last for approximately 5 years, but the life of any back-up battery can be
adversely affected by environmental conditions like moisture and heat. To get the longest service from
21
your back-up battery, do not place the AT&T Home Base in direct sunlight or in wet or extremely cold
environments.
To test the condition of your back-up battery, make sure the AT&T Home Base is powered on. Unplug the
AT&T Home Base from the wall power outlet. If the Power LED immediately starts blinking red, then the
back-up battery may need to be replaced. If the AT&T Home Base does not remain on (no LEDs are lit)
once unplugged from the wall power outlet, then the back-up battery needs to be replaced.
It is recommended that you test your back-up battery charge at least once per year and replace if
necessary.
To order a replacement back-up battery and for cost and warranty information, visit att.com and search
Home Base battery.
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).
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.
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. 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 needed.
How do I install my AT&T Home Base?
Refer to pages 8-14 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
22
wireless signal in order to maximize voice/data performance.
If the AT&T Home Base signal strength indicator does not display high signal strength (Blue) 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 (Blue) is recommended for optimal performance. A moderate signal (Green) may
be sufficient. If you do not see a blue/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.
Why don't I see the name of the caller on caller ID?
The AT&T Home Base, similar to other wireless devices, supports calling number identification.
However, contact names stored on your cordless home phone may display for incoming calls.
Can I move my AT&T Home Base and use it in another location?
Yes, you can use your device anywhere in the U.S. where AT&T is authorized to provide wireless
services. All you need is a power outlet and strong AT&T wireless signal.
