INTERFERENCE WARNING INFORMATION
If the apparatus code on the bottom of your voice terminal is marked with
the suffix “(RS)” (for example, 8510TND03A(RS)-003), then it complies
with electromagnetic interference criteria specified by the FCC as suitable
for residential (or business) installation. As such, the FCC requires us to
provide the following warning for Class B residential installations.
WARNING: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio and television communications. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of
the following measures:
■Reorient or relocate the receiving antennae.
■Increase the separation between the equipment and receiver.
■Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
■Consult the dealer or an experienced radio/tv technician for
help.
If the apparatus code on the bottom of your voice terminal is NOT marked
with the suffix “(RS)”, then it complies with criteria specified by the FCC as
suitable for a Class A business installation only. In this case, the FCC
requires us to provide the following warning for Class A business
installations.
WARNING: This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection aginst harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio and television
communications. Operation of this equipment in a residential area is likely
to cause harmful interference in which case the user will be required to
correct the interference at his own expense.

IMPORTANT SAFETY INSTRUCTIONS
Only the most careful attention has been devoted to quality standards in
the manufacture of your new telephone. 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 fullest advantage of your new
voice terminal. Then, retain these tips for later 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.
d Read and understand all instructions.
d Follow all warnings and instructions marked on the telephone.
d This telephone can be hazardous if immersed in water. To avoid the
possibility of electrical shock, do not use the telephone while you are
in the bathtub or shower, or when you are wet. If you accidentally
drop the telephone into water, do not retrieve the equipment until you
have first unplugged the line cord from the modular wall jack. Do not
reconnect the telephone until it has dried thoroughly.
d Avoid using the telephone (other than the cordless type) during
electrical storms in your immediate area. There is a remote 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 home or business, absolute
protection from lightning is impossible.
d If you suspect a natural gas leak in the vicinity of the telephone,
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.
d Never push objects of any kind into the telephone 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, dry
immediately, and refer any service problems to qualified service
personnel.
d To reduce the risk of electric shock, do not disassemble the
telephone. There are no user serviceable parts inside. Opening or
removing covers may expose you to hazardous voltages. Incorrect
reassembly can cause electric shock when the telephone is
subsequently used.

d Slots and openings in the housing must not be blocked or covered.
The openings should never be blocked by placing the telephone on a
sofa, rug or other similar surface. This product should never be
placed near or over a radiator or heat register. This product should
not be placed in a built-in installation unless proper ventilation is
provided.
d The telephone should be operated only from the type of power
source indicated on the marking label. If you are not sure of the type
of power supply being used, contact a qualified service person.
d Do not allow anything to rest on the power cord. Do not locate this
product where the cord will be abused by persons walking on it.
d Do not overload the AC wall outlets and extension cords as this can
result in risk of fire or electric shock.
d Before cleaning, disconnect all cords from the telephone. Do not
use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning.
d Disconnect the cords on the telephone and refer servicing to qualified
service personnel when these conditions exist:
When the power supply cord or plug is damaged or frayed.
If liquid has been spilled into the product.
If the product has been exposed to rain or water.
If the telephone does not operate normally by following the
operating instructions. Do not attempt to adjust any other
controls since doing so may result in damage and will require
extensive work by a qualified technician to restore the product to
normal operation.
If the product has been dropped or the housing has been
damaged.
If the product exhibits a distinct change in performance.
SAVE THESE INSTRUCTIONS
When you see this warning symbol on the product, refer to the
instructions booklet packed with the product for information before
proceeding.

Feature Descriptions
Here are brief descriptions of the voice features and the features
accessed with the softkeys, including what each one does and how you
might want to use it.
VOICE FEATURES
Conference Allows you to add an additional party to a call so that you
can conduct a conversation with more than one party. Use to set up
time-saving conferences, or to spontaneously include a party important
to a discussion.
Drop Disconnects you from a call without requiring you to hang up the

drop, but for which you have to interrupt briefly to do something else.
Message Retrieval Your Message light goes on to let you know that a
caller has left a message. Follow your System’s message retrieval
procedures to get your message.
Mute Turns off the microphone associated with the handset or the
speakerphone, whichever is currently active. Use when you want to
confer with someone in the room with you, but you do not want the other
party on the call to hear your conversation. (You are still able to hear the
person on the call.)
Redial (Last Number Dialed) Automatically redials the last number you
dialed manually from the dial pad, either an extension or an outside
number. Use to save time in redialing a busy or unanswered number.
Speakerphone Your voice terminal has either the Speaker (listen-only)

optimal performance. Use the built-in speakerphone any time you prefer
hands-free communications, both speaking and listening, or for group
conference situations.
Transfer Transfers a call from your voice terminal to another extension.
Use when your caller needs to speak further with someone else.
FEATURES ACCESSED WITH THE DISPLAY AND SOFTKEYS
The following features can be accessed using the 4 softkeys located
below the display.
Call Log The Call Log is initially set to list the 10 most recent incoming
unanswered calls only. An option is provided so that you may also
choose to access the most 10 recent answered calls, and the 10 most
recent outgoing calls placed from your voice terminal. Use to check on
calls that you missed (the unanswered calls) and to remind you of those
calls that you answered or placed most recently.
Clock For setting the date and time on your voice terminal display.
Contrast Change the contrast level of your display so that the letters or
numbers are darker or lighter against the background of the screen.
Directory Used to create and edit a personal directory of up to 30

Dir followed by a softkey button
associated with that Directory entry, a call is immediately placed to a
telephone number. The phone number appears on the display screen as
it dials.
Exit button Exits a display feature and returns the voice terminal display
to normal call-handling mode.
Lock Allows you to lock your Directory so that no one can make
unauthorized changes in it; lock your Call Log so that no one else can
view your Call Log entries; lock all of the softkeys so that no one can
view or change any of the features accessed by the softkeys.
8

Number of Names (on a Directory Page) Allows you to view either
4 names or 3 names + Quit on the second line of an individual Directory
page. If you choose to have 4 names on the Directory screen at one
time, you can leave the Directory or cancel calling a name in your
Directory only by pressing
cbbbbbc
bbbbb
Exit (rather than using Quit).
Personalized Ring Allows you to select your own personalized ringing
pattern from among 8 available patterns. Use to distinguish your voice
terminal’s ring from that of other nearby voice terminals.
Screen Timing (Rate at which the Display Message is Shown) Allows you
to set the length of time the display message remains on the screen.
There are 3 rates: Slow, Medium, and Fast.
Self-Test Performs a diagnostic test of your voice terminal including the
lights, ringer, dial pad keys, and display.
NOTE: When you perform a self-test of the voice terminal, it clears the
contents of the Call Log and the last number dialed from Redial, and
returns the volume control to the default setting.
Set Speakerphone When you set the built-in speakerphone, it performs
a test of the surrounding environment and adjusts itself for optimal
performance.
Tones A confirmation tone (sequential low and high tones) is provided
to let you know a selection has been accepted; an error tone (one beep)
alerts you that you made a mistake in your softkey entries. You may
choose to turn these softkey information tones on or off.
