How It Works
The AT&T Wireless Internet device 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,
unlike traditional home phone service.
The AT&T Wireless Internet device 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 backup battery in case of a power outage.

Device Installation
Before You Begin
The AT&T Wireless Internet device 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 outer
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 Wireless Internet device:
• 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 can simultaneously connect up to ten (10) devices per
Wi-Fi network (2.4 GHz and 5 GHz), twenty (20) total, and one (1) via Ethernet.

Helpful Tips
Home Answering Machines
If you choose to use your home answering machine instead of the voicemail provided
by your AT&T Wireless Internet device, you will need to set your answering machine
to pick up calls before four (4) rings, so that it picks up before the network voicemail
service. If you have a standalone answering machine, you can connect it to the
second “Phone” port on the back of your AT&T Wireless Internet device.
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 Wireless Internet device can be adjusted. Four volume levels are available
(level 1 through level 4), with the default setting at level 4. While on a call, press ** to
decrease the volume. Press ## to increase the volume. Each time ** or ## is pressed,
the volume is decreased or increased by one level.

Powering On/Off
The On/Off switch is used to turn your AT&T Wireless Internet device on or off. When
powered off, the AT&T Wireless Internet device will no longer send or receive calls,
but it will continue to charge the backup battery if still connected to the wall outlet.
To turn on your AT&T Wireless Internet device, slide the On/Off switch to the ON
position. The Power
light will turn solid green if connected to a power supply; it will
blink green if on backup battery power. To turn off your AT&T Wireless Internet device,
slide the On/Off switch to the OFF position.

TTY Support
TTY (Text Telephony) and TDD (Telecommunications Device for the Deaf) are
supported by the AT&T Wireless Internet device. 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.
To set the TTY mode or turn TTY support off, dial *983*889*n# on your connected
phone, replacing n with one of the following numbers:
• Replace n with 0 for TTY Off mode. Users who can hear and talk can turn off
TTY support. This is the default setting.
• Replace n with 1 for TTY Full mode. Users who cannot talk or hear can use this
mode to send and receive text messages through a TTY device.
• Replace n with 2 for VCO mode. Users who can talk but cannot hear can use this
mode to talk through the phone and receive responses via text messages.
• Replace n with 3 for HCO mode. Users who can hear but cannot talk can use this
mode to listen to calls and respond via text messages..
NOTE: If TTY support is enabled, it will be turned off automatically after seven (7) days
of inactivity, or when the device is powered off.

Important Information
E911 Service
For emergency calls, you may have to provide your location address to the 911 operator.

Power Outages
The AT&T Wireless Internet device has a backup battery, for use in the event of a
power outage, with talk time of approximately 150 minutes and standby time of
approximately 27 hours (depending on environmental factors). In the event of a
power outage (commercial power no longer available), the AT&T Wireless Internet
device will automatically begin using the backup 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 backup battery, you must plug a corded phone or landline
phone into one of the “Phone” ports on the AT&T Wireless Internet device.
The AT&T Wireless Internet device will disable Wi-Fi to conserve power while using
the backup battery when there are no devices connected. To re-enable Wi-Fi while
using the backup battery, press the WPS button. Or, if power is available, plug the

Radio Frequency (RF) Energy
This device meets the government’s requirements for exposure to radio waves.
This device is designed and manufactured not to exceed the emission limits for
exposure to radio frequency (RF) energy set by the Federal Communications
Commission of the U.S. Government:
The exposure standard for wireless mobile devices employs a unit of measurement
known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is
1.6 W/kg.*
While there may be differences between the SAR levels of various devices and at
various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this device with all reported
SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR
information on this device is on file with the FCC and can be found under the
Display Grant section of http://www.fcc.gov/oet/ea/fccid/ after searching
FCC ID: SRQ-MF279.
*Tests for SAR are conducted using standard operating positions accepted by the FCC with the
device transmitting at its highest certified power level in all tested frequency bands. Although
the SAR is determined at the highest certified power level, the actual SAR level of the device
while operating can be well below the maximum value. This is because the device is designed to
operate at multiple power levels so as to use only the power required to reach the network. In
general, the closer you are to a wireless base station antenna, the lower the power output.

FCC Regulations
This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
This device has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
