In tr od u ction  
The AT&T MLC-6 cordless telephone is compatible with your  
PARTNER™ Plus or PARTNER Communications System. It gives  
you the freedom of a cordless phone while providing the same  
features as a corded MLS™-model telephone.  
The MLC-6 cordless phone is functionally similar to the MLS-6™  
corded phone. The cordless phone can be programmed with  
system features and dialing restrictions the same as any other  
MLS-model phone.* For more information on how to program  
the system, see the documentation provided with the system.  
This booklet describes installation and troubleshooting procedures  
for the MLC-6 cordless phone. Also included with the phone is a  
card, Quick Reference: Display and Controls. After you have  
installed your phone and understand its controls and displays,  
follow call handling and programming instructions in Quick Refer-  
ence for Users with MLS-Model Telephones to use the cordless  
phone with your PARTNER Plus or PARTNER system. A supply of  
Quick Reference cards is included with the system’s control unit.  
P r iva cy In for m a tion  
Commercial radio scanners can monitor voice conversations over  
cordless phones. Privacy of communications cannot be guaran-  
teed when using cordless telephones.  
Au tom a tic Secu r ity Cod in g  
Your cordless telephone is provided with a digital security code  
that is automatically changed every time you place the handset in  
the base unit for 10 seconds or more. This code prevents un-  
authorized use of your line and will also prevent a user with an-  
other cordless handset from dialing calls on your line. However,  
the security code cannot prevent unauthorized monitoring of your  
telephone conversations by commercial radio scanners or similar  
devices.

In sta lla tion  
Im p or ta n t:  
Before beginning installation, please read and understand  
“Important Safety Instructions” and “Safety Instructions for  
Installation Personnel” at the beginning of this booklet.  
Be sure the base is unplugged before you begin.  
P osition in g th e Ba se  
The MLC-6 cordless phone uses radio transmissions to communi-  
cate. Its range depends on your particular operating environment,  
and can be improved by placing the base in an optimal location.  
The base can be placed on a desk or table or mounted on a wall,  
preferably one that is not made of metal.  
Before you install the phone, note the following considerations  
regarding its location and use:  
Mount the base near the center of the area in which the hand-  
set will be used, but at least 20 feet away from the control unit.  
Install the base within 6 feet of a properly grounded 3-prong  
electrical outlet that is not controlled by an on/off switch.  
The base should not share the same power line or be within 6  
feet of electromagnetic equipment such as electric motors, or  
equipment with microprocessors such as answering machines,  
personal computers, and fax machines.  
If your phone system uses an uninterruptable power supply,  
such as a backup generator, be sure to connect the base for  
the cordless phone to that power supply.  
If other people in your area also use cordless phones, assign  
different channels for their phones to help prevent interference.  
Using different channels will not prevent monitoring by radio  
scanners and similar devices, however. To assign different  
channels to each cordless phone, follow the instructions in  
“Programming Channels (More Than One Cordless Phone).”  
If more than one cordless phone is being used, do not place a  
handset from one cordless phone into the base of another. If  
this accidentally occurs, place each handset in the correct  
base for at least 10 seconds.  
9
   
The handset does not need to be located with the base except for  
charging. For best coverage, place the base in a central location,  
away from concentrations of structural metal such as steel and  
aluminum or reinforced concrete. Use the handset at another desk  
or while moving about your work location.  
For indoor use, place the base so that walls do not block the base  
from the area where the handset will be used. (See the figure  
below.) Intervening walls will reduce the phone’s range.  
Poor Base Location  
(Indoor Use)  
Optimum Base Location  
(Indoor Use)  
For outdoor use, place the base near a window facing the outdoor  
area where the handset will be used. (See the figure below.) Do  
not install the base where it will be exposed to direct sunlight.  
Optimum Base Location  
(Outdoor Use)  
If you have questions about the installation of your cordless  
telephone or the location of the base, refer to “Troubleshooting” or  
call the AT&T Helpline at 1 800 628-2888.  
10  
In sta llin g th e Ba se  
If desk mounting, skip step 1 and steps 3–6.  
If wall mounting, remove the  
four screws in the bottom of the  
base. Turn the bottom of the base  
180° as shown above, then screw it  
back into place.  
Plug one end of the modular  
telephone cord into the jack on the  
bottom of the base. Then route it  
and the AC power cord along their  
respective channels.  
Reverse the handset hook.  
Press the hook down and slide it up  
out of its slot, then turn the hook  
upside down and replace it in the  
slot, with the top protruding so the  
handset can hang from it.  
Mark screw locations using  
the Wall Mount Template on the  
inside back cover of this booklet.  
Choose a location backed by a  
wooden stud. (If no wooden stud is  
available, use toggle bolts instead  
of the wood screws provided.)  
11  
 
Install mounting sleeves and  
screws. Lightly tap a nail into marks  
on wall to start holes. Then slip each  
screw into a mounting sleeve (with  
screw head in wider barrel of sleeve  
and screw securely into wall.  
Mount the base. Place the  
base over the screws, than slide it  
downward slightly to lock it into  
place.  
Plug power cord/adapter  
into a properly grounded 3-prong  
wall outlet.  
Plug modular telephone cord  
into a modular wall jack. (Alterna-  
tively, you can plug the cord  
directly into a system 206 module,  
but you must place the base at  
least 20 feet from the 206 module.)  
If the base is mounted on a flat surface, slide the Quick Reference  
under the base. If the base is wall-mounted, place the Quick  
Reference near the base.  
12  
In ser tin g th e Ba tter y P a ck  
If a battery pack is already in  
the compartment, first unplug the  
battery cord from the handset and  
remove the old battery pack.  
Place the new battery pack in the  
compartment with the battery cord  
coming from the top left side of the  
battery pack.  
Remove battery cover  
from the handset by pressing down  
on the raised dots and sliding the  
cover towards you.  
Plug the white plastic end of the cord attached to the battery pack  
into the battery connector jack compartment. The battery contacts  
should face down.  
Replace the cover by sliding it forward until it snaps into place. Be careful  
not to pinch the battery cord.  
13  
 
Rep la cin g th e Ba tter y P a ck  
When the power in the battery pack for the MLC-6 phone is  
low, the message BATT appears in the handset display. The life of  
the battery pack is approximately two years. To order a replace-  
ment battery pack, see “Ordering Replacement Parts.”  
To install a new battery pack, see “Inserting the Battery Pack.” Be  
sure to properly dispose of the old battery.  
WAR N I N G :  
Do not open or mutilate batteries. They contain caustic and  
toxic chemicals. Do not dispose of in fires. The batteries can  
explode and cause severe personal injury. Dispose of batter-  
ies in accordance with the local sanitation codes.  
Ch a r gin g th e Ba tter ies  
Charge the batteries before using the cordless phone for the first  
time. To charge, simply place the handset on the base, making  
sure the base is plugged into an AC outlet. The Charge Indicator  
on the base lights up to show that the handset is seated properly  
and the batteries are charging. (If the battery is completely  
drained, you will hear a brief high-pitched sound when you place  
the handset in the base.)  
It takes approximately eight hours to fully charge a drained battery.  
If the handset is turned on for four hours or more a day, it is a good  
practice to recharge the batteries at least once daily.  
14  
   
In sta llin g th e F lexible An ten n a  
The handset comes with a rigid telescoping antenna installed.  
Normal operation of the cordless phone requires you to manually  
extend this antenna when making a call. If you prefer, you can use  
the flexible antenna, which does not need to be extended or  
retracted.  
To install the flexible antenna:  
1. Remove the telescoping antenna from the handset by  
unscrewing it counterclockwise.  
2. Insert the end of the flexible antenna into the handset and  
screw it in clockwise until it is firmly seated.

Treated properly, your telephone will require no maintenance other  
than periodic cleaning. To clean, wipe the housing with a soft,  
dust-free cloth. If absolutely necessary, clean it with a soft cloth  
slightly dampened with a mild soap and water solution. Dry quickly  
with a soft cloth.  
To prevent damaging the phone, avoid dropping the base and the  
handset. Always place the handset on the base gently. To reduce  
the risk of injury, fire, or electric shock, always follow the basic  
safety precautions listed at the beginning of this booklet.  
C AU T I O N :  
Your telephone contains sensitive electronic parts. Never  
expose it to or submerge it in any kind of liquid, and never use  
detergents, alcohols, solvents, abrasive cleaners, or an  
excess amount of water when cleaning the housing and  
faceplate. To do so could damage the phone.

design. The repair or replacement will be warranted for the remain-  
der of the original one-year warranty period, plus the number of  
days, if any, that you were without your telephone while we were  
performing repairs. If we determine that your telephone cannot be  
repaired or replaced, we will refund its purchase price to you.  
Lim ita tion :  
This warranty applies only if you purchased your telephone  
from AT&T or an AT&T Authorized Dealer. Implied warranties,  
including those of fitness for a particular purpose and mer-  
chantability (an unwritten warranty that the product is fit for  
ordinary use), are limited to one year from date of purchase.  
We will not pay for loss of time, inconvenience, loss of use of  
your telephone, or property damage caused by your telephone  
or its failure to work, or any other incidental or consequential  
damages.  
Some states do not allow limitations on how long an implied  
warranty lasts or the exclusion or limitation of incidental or conse-  
quential damages, so the above exclusions or limitations may not  
apply to you.

If you need service on your telephone after the one-year warranty  
period, here’s what you do:  
If you bought your telephone from AT&T or if you bought it from an  
Authorized AT&T Dealer, and you also signed an AT&T post-  
warranty Maintenance Agreement, call the Helpline. Your post-  
warranty Maintenance Agreement entitles you to service calls with  
no additional charges for parts or labor.  
If you bought your telephone from AT&T but you did not buy a post-  
warranty maintenance contract, call our Helpline for service charges  
and assistance.  
If you bought your telephone from an AT&T Authorized Dealer but  
you did not buy AT&T post-warranty service, call your Dealer for  
assistance (or call our Helpline).  
Im p or ta n t Notice:  
We expect your telephone will work well for you for many years.  
However, we do recommend that you buy an AT&T post-warranty  
Maintenance Agreement if you are concerned about the expense of  
repair or replacement of your telephone after the one-year warranty  
period. See your AT&T Representative, your Dealer, or call us toll  
free at 1 800 247-7000 if you would like to talk about the coverage  
and price of a Maintenance Agreement.

F CC In for m a tion  
Federal Communications Commission (FCC) rules require that you  
be notified of the following:  
F CC P a r t 15 Ru les  
The AT&T MLC-6 Cordless Telephone has been tested and has  
been found to comply with FCC Part 15 Rules. These specifica-  
tions are designed to provide reasonable protection against  
harmful interference in a commercial or residential installation. This  
cordless telephone generates, uses, and can radiate radio fre-  
quency energy and, if not installed and used in accordance with  
the instructions, may cause harmful interference to radio communi-  
cations. However, there is no guarantee that interference will not  
occur in a particular installation. If the telephone does cause  
harmful interference to radio or television reception, which can be  
determined by turning the telephone off and on, the user is encour-  
aged to try to correct the interference by one or more of the  
following measures:  
Where it can be done safely, reorient the receiving television or  
radio antenna.  
To the extent possible, relocate the television, radio, or other  
receiver with respect to the telephone.  
Plug the telephone into an AC outlet that is not on the same  
circuit as one used by the radio or television.  
Hea r in g Aid Com p a tibility  
This cordless telephone is compatible with inductively-coupled  
hearing aids.
