and handset lifter

Introduction

The TL7812 is a cordless headset and base that allows you to
have handsfree phone conversations. The package also comes
with the TL7100 handset lifter, making it convenient to answer
and end calls right from the headset. It can be used in different
ways depending on your needs. Choose from the following three
options. Connect your TL7812:

To a traditional corded telephone (pages 11-12). Connect the
headset base to a corded telephone and install the lifter on
your corded telephone. You can use the headset to remotely
control the lifter for answering or hanging up a call.

To both a corded phone and computer (pages 13-15).
Connect the headset base to a corded telephone and install
the lifter on your corded telephone. Use the USB cable to
connect the headset base and your PC. You can make and
answer VoIP calls through SkypeTM and Microsoft Lync , or
landline calls using the AT&T Softphone Call Manager.

Visit www.smbtelephones.att.com/downloads
to download the AT&T Softphone Call Manager. For
installation and operation instructions of the software, refer
to the Installation and Operation Guide which can also be
downloaded at

To a telephone line only (page 16). If you do not want to

install the lifter on the corded handset, you can simply connect
the headset to a telephone wall jack through the line splitter
provided. Use the telephones on the same telephone line to
make or answer calls. The headset is a supplementary device
that can join the calls.
