CAUTION: To prevent overheating of the 206 module, do not obstruct the sides.
Do not leave objects (books, cartons, etc.) lying on top of it or resting on its sides.
WARNING: There are no user-serviceable parts inside the 206 modules or the
module connector. Hazardous voltages within. DO NOT OPEN!

The telephone stand packed with the PARTNER phone is required for wall mounting, optional for desk mounting.
To connect a PARTNER phone to the system, use only the 2-pair (4-conductor) telephone cords included with
the phone. Use the mounting cord to connect the phone to a wall jack. Or connect the phone directly to a
telephone cord connected to a 206 module.
Do not install PARTNER or standard single-line phones out of doors or in a different building from your 206
module(s).

Place the phone/stand assembly
over the wall jack, pushing any excess
cord into the space inside the stand. To
mount the assembly on the wall, place
the screw keyholes on the stand over the
studs above and below the wall jack,
then pull the assembly down gently.Insert the cord through the centerof the stand and plug it into the jack on
the bottom of the phone.
Plug one end of the handset cord
into the jack on the handset. Plug the
other end into the jack on the side of the
base. Place the handset in the cradle.
Place the Quick Reference card near the
phone. (You may want to place it on top
of the phone, so the card leans against
the wall.)

Combining Two Devices
on One Extension
You can combine a PARTNER phone of another standard device or two standard devices on one extension.
The total REN (Ringer Equivalence Number) for the devices must be 2 or less (see p. 1-3). Do not combine
two PARTNER phones on one extension jack.
Use only an AT&T 267F2 bridging adapter to combine devices (two included with each 206 module).
If the standard device’s mounting cord is loose in the bridging adapter, replace the cord with an AT&T D2R
mounting cord (see appendix C).

Connecting Other Equipment
In addition to standard equipment, you can connect a variety of headsets and loudspeaker paging systems to the
system. To choose a headset or paging system to meet your needs, call your AT&T representative (or one of the
phone numbers listed on p. 1-4). Follow the instructions provided with the equipment for installation and use.

							Overview
After completing the installation steps in chapter 2, your system is fully
operational and ready to go. All the system’s settings are preset and require no
adjustment. However, if you want, you can customize your system to meet your
specific needs by changing some of the factory settings. Following are the
different ways you can customize your system.
n
n
n
n
n
nOutgoing Call Restriction. The system is set up at the factory to allow all
phones to make all calls. However, you can prevent any telephone from
making an outside call. A restricted phone can only make intercom (inside)
calls. This can help you control unauthorized phone activity and keep costs
down. See p. 3-2.
Automatic Line Selection. When you lift a phone’s handset, normally the
system automatically connects you to an available outside line. The system
is set at the factory to connect you automatically to outside line 1. If line 1 is
busy, then you are connected to line 2; if line 2 is busy, you are connected to
line 3; and so on. If all the outside lines are busy, you will be connected to
an intercom (inside) line. Automatic Line Selection allows you to change the
sequence of lines to which a user is automatically connected. For examples
of situations when you might want to change the Automatic Line Selection,
and for instructions on how to do it, see p. 3-3.
Line Ringing. The system comes set up so that each line on all phones ring
when a call comes in. You can, however, set up a line or lines on a
PARTNER phone so they do not ring. (Even though the phone doesn’t ring,
you can tell a call is coming through by the flashing lights next to the line
buttons.) If the phone is set up not to ring, you can still answer the call. See
p. 3-4.
Abbreviated Ringing. Normally, when you are busy on a call, an incoming
call will ring out loud once, and then stop ringing while the green light next to
the line or intercom button continues to flash. You can change this so that a
phone continues to ring until it is answered. See p. 3-4.
Speed Dialing. The system can store up to 10 outside numbers that users
can dial by pressing only three buttons. You might want to store numbers of
business associates, suppliers—any numbers that the people who use your
system dial all the time. See p. 3-5.
Auto Dialing. Anyone with a PARTNER 12-button phone can store up to
eight additional outside numbers that can be dialed with a single touch. See
p. 3-6 and 4-4.

							Changing Factory Settings
The system’s factory settings can be changed only from extension 10 using a
PARTNER phone. You can change settings anytime, even when you are on a
call. This allows you to change settings while talking on the AT&T Helpline. Just
remember that (except for Auto Dialing) you must change settings from exten-
sion 10 using a PARTNER phone.
Step-by-step instructions are given below for each setting.
Outgoing Call Restriction
An extension can be either unrestricted (can make inside and outside calls) or
restricted (can only make inside calls).* The restrivted setting is used for tele-
phones in reception areas or other public rooms where you want to prevent any-
one from making outgoing calls. It is also useful for prohibiting calls from ware-
house extensions, or from extensions that are used to take phone orders. The
factory setting is unrestricted for all extensions, so change the setting only to
restrict certain extensions from making outside calls.
Procedure:

6.Press [ Feature ] [ 0 ] [ 0 ].
The phone beeps once, the lights of the four line buttons no longer show the
status of the lines, and the light next to the [
 Spkr ] button is green flutter.
Press the left [ Intercom ] button twice.
The light next to the button is green steady.
Press [ # ] [ 4 ] [ 0 ] [ 1 ].
Dial the 2-digit number (10 to 21) of the extension you want to change.
The Message light is steady red if the current setting for the extension is no res-
triction, flashing red if the current setting is restricted.
Press [ 1 ] for “no restriction,” or [ 2 ] for “restricted.” If you make a mistake
or want to change the setting, return to step 3. To change the setting at
another extension, return to step 3.
When you are finished, press [
 Feature ] [ 0 ] [ 0 ].
*
While procedures that restrict dialing are very effective, absolute protection against misuse cannot be guaranteed. PARTNER
phones give more protection than standard phones. Therefore, we strongly recommend that you install PARTNER phones
where restricting phone use is important.
