• Do not dispose of the battery in a fire. Like other batteries of this type, it
could explode if burned. Check with local codes for special disposal instruc-
tions.
• Do not open or mutilate the battery. Released electrolyte is corrosive and may
cause damage to the eyes or skin. It may be toxic if swallowed.
• Exercise care in handling batteries in order not to create a short circuit. Do
not allow conductive materials such as rings, bracelets, or keys to touch the
battery. The battery or conductor may overheat and cause harm.
• Use the battery identified for use with this product only in accordance with
the instructions and limitations specified in this manual.
• Observe proper polarity orientation between the battery and metallic con-
tacts.
• Do not disassemble your telephone. There are no user-serviceable parts in-
side. Refer to qualified service personnel for servicing.
STOP!
Do you receive DSL, (Digital subscriber line,) service for high-
speed internet access through your telephone line(s) from your
telephone company? If so, you will need to add either DSL
splitters and/or microfilters to your installation. See page 9 of
the installation guide.

Introduction
This AT&T Small Business System is expandable to a 16-extension telephone
system. The 1070 telephone is compatible with 1040 and 1080 telephones.
For details, see the Installation Guide. This system is not compatible with any
other AT&T 4-line small business telephones, except for the 1040 and 1080
telephones.
The 1070 telephone is hearing-aid compatible and can be connected to up
to four incoming telephone lines. This telephone features a speakerphone
for handsfree use and a headset jack compatible with most two-band 2.5mm
headsets (sold separately). There are two additional ports, known as AUX
jacks or data ports, available for connecting the telephone to another device
such as a fax machine or modem.
The 1070 allows paging, intercom and call transfers between system telephones
and is capable of connecting three parties in the same conference call.
This telephone also features a 32-number one- and two-touch memory
for faster dialing and has a directory which can store up to 200 additional
numbers with names.
This telephone has a caller ID feature which supports caller ID with call
waiting service. (Caller ID services are subscriber services available from many
local telephone companies for a fee.)
If there is a 1080 telephone in your system that is an auto attendant, it may
record messages for your set.
The 1070 telephone is compatible with Centrex service. Centrex is a special
subscriber service which may be available from your local telephone company
for a fee. If you subscribe to Centrex service, refer to the Centrex operation
section (page 66).
This user's manual contains detailed instructions for using your AT&T Small
Business System 1070 telephone. Please read this manual before using this
1070 telephone.
