IMPORTANT USER SAFETY
INSTRUCTIONS
The most careful attention has been devoted to quality standards in the
manufacture of your new voice terminal. Safety is a major factor in the design of
every set. But, safety is YOUR responsibility too.
Please read carefully the helpful tips listed below and on the next page. These
suggestions will enable you to take full advantage of your new voice terminal. Then,
retain these tips for later use.
CAUTION: This voice terminal is NOT for residential use. It is for business systems
applications ONLY. Use in a residential environment could result in an electrical
short circuit when the telephone wiring is set up to provide other applications, for
example, for appliance control or power transformers. The AC power used in these
applications may create a safety hazard by placing a direct short circuit across the
telephone wiring.
Use
When using your telephone equipment, the following safety precautions should
always be followed to reduce the risk of fire, electric shock, and injury to persons.
•Read and understand all instructions.
•Follow all warnings and instructions marked on the telephone.
•This telephone can be hazardous if immersed in water. To avoid the possibility of
electric shock, do not use it while you are wet. If you accidentally drop the
telephone into water, do not retrieve it until you have first unplugged the line cord
from the modular jack. Then, call service personnel to ask about a replacement.
•Avoid using the telephone during electrical storms in your immediate area. There
is a risk of electric shock from lightning. Urgent calls should be brief. Even
though protective measures may have been installed to limit electrical surges from
entering your business, absolute protection from lightning is impossible.
•If you suspect a natural gas leak, report it immediately, but use a telephone away
from the area in question. The telephone’s electrical contacts could generate a tiny
spark. While unlikely, it is possible that this spark could ignite heavy
concentrations of gas.

•Never push objects of any kind into the equipment through housing slots since
they may touch hazardous voltage points or short out parts that could result in a
risk of electric shock. Never spill liquid of any kind on the telephone. If liquid is
spilled, however, refer servicing to proper service personnel.
•To reduce the risk of electric shock, do not disassemble this telephone. There are
no user serviceable parts. Opening or removing covers may expose you to
hazardous voltages. Incorrect reassembly can cause electric shock when the
telephone is subsequently used.
Service
1.Before cleaning, unplug the telephone from the modular wall jack. Do not use
liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
2.Unplug the telephone from the modular wall jack. Be sure to refer servicing to
qualified service personnel when these conditions exist:
—If liquid has been spilled into the telephone.
—If the telephone has been exposed to rain or water.
—If the telephone has been dropped or the housing has been damaged.
—If you note a distinct change in the performance of the telephone.

WARNING: This voice terminal is NOT for residential use. It is for business
systems applications ONLY. Use in a residential environment could result in an
electrical short circuit when the telephone wiring is set up to provide other
applications, for example, for appliance control or power transformers. The AC
power used in these applications may create a safety hazard by placing a direct short
circuit across the telephone wiring.

ADDITIONAL INSTALLATION WARNING
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN CAUSE
DAMAGE TO THE TERMINAL OR CAUSE THE ASSOCIATED PBX
CIRCUIT PACK TO REMOVE POWER TO THE TERMINAL. IN
EITHER CASE THE TERMINAL WILL NOT FUNCTION CORRECTLY.
The design of this product allows it to operate on either 2-wire or
4-wire DCP circuits. In order for the terminal to function properly in either 2-wire
or 4-wire installations, there must be NO INTERCONNECTIONS between the
wire pairs used for 2-wire and 4-wire operation. Bridging or paralleling of these
pairs can result in damage to the terminal or can cause the PBX circuit pack to
remove power to the terminal.
REMOVE ALL CONNECTIONS BETWEEN PAIRS BEFORE
CONNECTING THE TERMINAL.
For 2-wire operation, if you need to plug the voice terminal into a
4-pin or 6-pin wall jack, instead of a standard 8-pin modular jack, refer to the
“Line Interface” table below Figure 1 in The
8400-Series Voice Terminals Instructions for Installation, Switch Administration,
and Programming the Options, 555-110-725, to insure that the wires from the 4-
pin or 6-pin wall jack are connected to the correct pins on the terminal “LINE”
jack.
4-WIRE installations MUST ONLY have PBX connections on pair 2 and pair 3
and, if necessary, auxiliary power must be connected to pair 4.
2-WIRE installations MUST ONLY have PBX connections on
pair 1 and, if necessary, auxiliary power must be connected to
pair 4.

INSTALLING YOUR VOICE TERMINAL
IMPORTANT: For a fuller description of installing the 8400-Series voice terminals
and procedures on administering these sets and programming such options as
enabling/disabling the speakerphone or one-way speaker, enabling/disabling the Mute
function, selecting ringing preference, or selecting handset and speaker volume
control, see the 8400-Series Voice Terminals Instructions for Installation, Switch
Administration, and Programming the Options, 555-015-725. (This document can be
ordered from the Lucent Technologies BCS Publications Center at 1 800 457-1235.)
Distance Limitations
In 4-wire operation, the voice terminal must be within 5,000 feet of the PBX using
22-gauge or 24-gauge wire, and within 4,000 feet of the PBX using
26-gauge wire.
In 2-wire operation, the voice terminal must be within 5,500 feet of the PBX using
22-gauge wire, within 3,500 feet of the PBX using 24-gauge wire, and within 2,200
feet of the PBX using 26-gauge wire.
Auxiliary Power
In both a 4-wire or 2-wire configuration, most 8400-Series voice terminals are
phantom powered from the PBX. However, you will need auxiliary power in the
following instances:
•If you are using an 8411 or 8434DX voice terminal (These sets require auxiliary
power.)
•If you have an 801A Expansion Module (used ONLY with the 8434DX voice
terminal connected to a DEFINITY®Communications System G3V3.3 or later
switch)
•If there is an attached adjunct equipment, such as an S201A Speakerphone
The following power supplies can be used with the 8400-Series voice terminals:
•Stand-alone 1151A1 Power Supply (PEC: 2404-010;
Comcode: 107785693) and 1151A2 Power Supply with Battery Holdover
(PEC: 2404-012; Comcode: 107785339)
•Stand-alone MSP-1 (PEC: 2404-010; Comcode: 406743419)
•1145A Bulk Power Supply (PEC: 2404-011;
Comcode: 106448939)
Battery for the 1145A (2.5 amp per hour battery)
(Comcode: 106448921)

2
•1145B1 Bulk Power Supply (PEC: 2404-010)
Battery for the 1145B1 (2 amp battery = PEC: 24700;
or 5 amp battery = PEC: 24701)
•KS-22911 L2 (replaced by the MSP-1 Power Supply and 1151A1/A2 Power
Supplies) — This power supply cannot be used with the 8411.
NOTES: The MSP-1, the 1151A1 and A2, and the 1145B are global power supplies.
It is recommended that the 1145A and the 1145B Bulk Power Supplies be used as
auxiliary power for the 8434DX voice terminal. These power supplies provide battery
back-up, and therefore when power outages occur, the 8434DX display will continue
to operate.
If an 8434DX voice terminal with attached adjunct equipment is connected to an
expansion module, it should be locally powered by an MSP-1 or an 1151A1 or A2. If
this configuration is closet powered by an 1145A, two ports must be used. A KS-
22911 L2 cannot be used in this situation.
General Notes for Installation
Regardless of which configuration is in use, ALL wiring between the PBX and the
terminal MUST consist of twisted-pairs, including the modular line cord. The line
cord must be a D8W, which consists of four twisted-pairs, or a Lucent Technologies
approved equivalent.
Twisted-pair wiring is used to make lines less sensitive to crosstalk. Therefore, failure
to use twisted pair wiring may result in less-than-optimum performance of the
terminal and may also contribute to problems with the line.
An 8-wire modular cord MUST be used for all 4-wire and any 2-wire installations
requiring auxiliary power.
You do NOT need to change any settings on the voice terminal for 2-wire or 4-wire
installations. The voice terminal is able to detect whether it is in a
2-wire or a 4-wire configuration.
Desktop Installation
The following instructions are for a desktop installation. If you are mounting the
voice terminal on the wall, proceed to the next section, “Wall Installation.”
NOTE: During the desktop installation procedure, refer to Figures 1, 2, 3, and 4
for the location of the jacks referred to in the following steps.
•Figure 1 shows the back of one of the 8403 voice terminal models. (Use this
figure for installing the 8403, 8405, and 8410. However, note that the
location of the jacks on the back of your voice terminal may differ slightly.)
•Figure 2 shows the back of the 8411 voice terminal, and Figure 3 shows the
two jacks on the rear of the 8411. Use the RS-232-D jack for connecting a
PC dedicated to PassageWay®Solution software and the Analog Adjunct

3
jack for connecting an analog device such as a modem, answering
machines, fax machines, audio teleconferencing equipment, or TTY
machines commonly used by the hearing impaired.
•Figure 4 shows the back of the 8434DX voice terminal. (Note that the jacks
on the back of your voice terminal may be in a slightly different location.)
1. Turn the voice terminal face down on a flat surface.
2. If you are installing an 8405D, 8405D Plus, or 8410D voice terminal, refer to
“Adjusting the 8405 and 8410 Voice Terminal Desktop Stand” for choosing
whether the desktop stand should be in the high or low position. On the 8411,
decide whether you want the kickstand in the up or the down position.
NOTE: Figure 1 shows the back of the 8403 voice terminal, although the
location of the routing channels on some 8403 voice terminals and on the 8405
and 8410 may differ slightly from the 8403 shown in the figure. Also, the
Handset jack on some 8403 voice terminals and on the 8405 and 8410 may be in
a different location.
3. Snap one end of the line cord into the “LINE” jack and the adjunct cord (if
applicable) into the Adjunct jack on the back of the voice terminal. (The
Adjunct jack is labeled , except on the 8411, where it is labeled
“ADJUNCT.”) For more information on installing adjuncts, refer to the section
“Attaching Adjunct Equipment.”
IMPORTANT: If you are routing the cords on the 8405D, 8405D Plus, or
8410D voice terminal and the desktop stand is in the high position, you may
need to place the cords through the long, rectangular opening that surrounds the
jacks and plug the cords into the jacks BEFORE you insert the desktop stand
onto the back of the voice terminal.
4. Thread the line cord (and adjunct cord, if applicable) through the routing
channel leading to the top of the desktop stand, as shown in Figure 1 (on the
8403, 8405, and 8410 voice terminals), Figure 2 (on the 8411 voice terminal)
and Figure 4 (on the 8434DX voice terminal). Note, however, that the location
of the routing channels on some voice terminals may differ from those on the
voice terminals in these figures. Make sure that each cord is placed securely
under the square tabs in the routing channel.
5. If you are using an 8434DX with an attached 801A Expansion Module, plug the
D6AP-87 cord, shipped with the expansion module, into the Expansion Module
jack on the voice terminal (labeled “EX MOD”) and then plug the free end of
the cord into the jack on the expansion module. The cord should be threaded

NOTE: If the voice terminal is being used with the 4-wire
7400B Plus or 2-wire 8400B Plus data module, the telephone line cord
connects to the Phone jack on the 7400B Plus or 8400B Plus instead of to
the wall jack. The Line connector on the 7400B Plus or 8400B Plus is
then connected to the wall jack. Refer to the 7400B Plus Data Module
User’s Guide or 8400B Plus Data Module User’s Guide for further
information on using either of these data modules.
NOTE: The 7400B Plus or 8400B Plus data module cannot be used with
the 8411 when the voice terminal is optioned for a second telephone
number for the Analog Adjunct jack. Refer to the 7400B Plus Data
Module User’s Guide or 8400B Plus Data Module User’s Guide for
further information on using either of these data modules.
