Blinking period: 2s ) 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 youll be using your home phone, computer, or Wi-Fi enabled devices. 7 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). 8 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 (0C - 45F). B Turn on Your Device 1. Plug the power cord into an electrical wall outlet. 2. Connect the other end of the power cord into the Power Input port on the back of your AT&T Home Base. 3. Slide the ON/OFF button to the ON position and you'll see the power light stays steady green. 9 C Check the Wireless Signal Wait a few seconds for the signal strength light to turn on, while your device connects to the cellular network. Confirm signal strength light is blue for optimal performance. Green indicates a moderate signal and may be sufficient. NOTE: If you do not see a blue/green light, you may want to choose another location in your home, such as near a window or outside wall. STEP 2: Connect Your Phone A Unplug your Phone from the Wall Jack The AT&T Home Base is not used with your home phone wall jack. NOTE: If you have a cordless phone, keep it plugged into a power outlet. 10 B Connect your Phone to the Device Plug your phone into the "Phone 1"port on the AT&T Home Base, using your existing phone cable or the included phone cable. NOTE: Do not plug the AT&T Home Base or your phones into your wall jacks. C Place a Test Call Place a test call from your connected home phone. Make sure to dial the 10-digit phone number, including area code. For best results, place the cordless phone base at least 12 inches from the AT&T Home Base. Important Phone Tips Voicemail is included with your service. Dial "1" to set up and access. If you choose to use an answering machine instead, set it to fewer than four (4) rings. To place phones throughout your home, use a cordless phone system with multiple handsets. Wall jacks are not used with the AT&T Home Base. The "Phone 2" port can be used to connect an additional phone or standalone answering machine. It uses the same phone number as the "Phone 1" port. 11 Your AT&T Home Base does not support incoming/outgoing fax service or home alarm systems. Your AT&T Home Base does not support rotary or pulse-dialing phones. Details on using voicemail and transferring a landline phone number can be found on pages 11-12.

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 19 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 20 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:
