AT&T WF721
Wireless Home Phone (“WHP”) device is a mobile device that may be used with home phone equipment in different locations in the U.S. WHP device requires a battery to be installed in the device at all times to operate. In the event of a power outage, the battery can be used as a back-up battery. However, a landline phone requiring separate electric power to operate (e.g. cordless phones) connected to a WHP device will not place or receive calls (including 911 calls) during a power outage. For emergency calls, you may have to provide your location address to the 911 operator. Landline home phone equipment is not included. Provides voice service only. Not compatible with data or 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. WHP device is sold for use on the AT&T wireless network and cannot be activated on other carriers’ wireless networks. If your WHP device is roaming, AT&T’s off-net usage restrictions apply.

How It Works
The Wireless Home Phone device uses the AT&T cellular network to provide phone service to your cordless or corded 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.
The Wireless Home Phone device provides many calling services, such as voicemail, Caller Number ID, Call Waiting, Call Forwarding, and Three-way Calling for your home phone(s).
Device Installation
Before You Begin
Your device works exclusively with the AT&T cellular network and DOES NOT use your home phone wall jacks.
Your device should be located:

• Nearanelectricalwalloutlet.
Select which phone(s) you will use with the Wireless Home Phone device:
• Acordlessphonesystemwithmultiplehandsetsshouldbe used to place phones throughout your home.
• Ifusinganexistingphone,unplugitfromthewalljack.
1 Install the Battery
Insert the battery.
Note: Battery must be installed at all times for your Wireless Home Phone device to operate.
Install the battery cover.
NOTES:
•The battery must be installed at all times for your Wireless Home Phone device to operate properly, even when plugged into a power source. It may take five (5) hours to fully charge (battery will charge inside the device while connected to a power supply).
•Chargetimemaybeimpactedbyenvironmentalfactors, and the battery will stop charging when the ambient temperature is outside of the temperature range allowed for charging (32 °F – 131 °F).
