The Graphic Key Telephone (GKT) meets all your telephony and office needs. The benefits you receive from
working with the GKT will become an invaluable part of your work environment. While the technology employed in
the GKT is state of the art, using the telephone is simple and straightforward. Immediately you will appreciate the
large Graphic Display and easy to reach Softkeys. Depending on the state of the telephone, the Graphic Display
automatically changes to provide you with the appropriate options. In addition, on-line help is available at any time.
Simply press the Help button to get step-by-step instructions.
The GKT functions include a user created Directory loaded at the GKT and a Private password protected Directory.
The Directory can be configured so that important or Frequently Dialed Numbers always reside on the display when
accessing the directory. Other GKT functions include Coral telephony features easily activated by using the softkeys
at the side of the display, a calculator, a calendar and the on-line Help function.
The GKT works as a stand-alone unit or can utilize the GKT software package installed on your PC. The software
package enables you to backup your Directory as well as download new/updated Directories or GKT software
versions.
Beyond streamlining the functionality of your GKT telephone, any option can be quickly located by using the
function aides such as SEARCH, GO TO, and the scroll keys.
This User’s Guide provides an overview of the GKT and instructions on how to accomplish several tasks. Additional
instructions on other feature rich options are located in the On-line Help or in the Appendices located at the end of
this guide. The GKT is a top-of-the-line telephone from the Coral family of telephones.
Enjoy your new GKT telephone!

USING THE GRAPHIC DISPLAY
The GKT Graphic Display provides an easy to use control interface. On this display, several different classes of
function information and controls are found. During normal operation, the current function assumes control over the
entire area of the Graphic Display and all of the Softkeys. Meanwhile, the System Lines which usually include the
time, date, and station name and number, automatically change to relay pertinent information about telephony states
and operations.
Several icons also appear in the Graphic Display. See the following section Graphic Display Icons for Icon
definitions. Five Softkeys located on each side of the display act as triggers for any currently displayed GKT
functions or options. All of the information in the Graphic Display continually changes to reflect options related to
the current state of the GKT. In this manner, no matter which state the telephone is in (i.e. Idle, or Ringing) the
relevant option is always next to and enabled by one of the Softkeys.

USING THE HARD KEYS
Use the Hard keys to administer GKT basic operations. The Hard keys, like the Softkeys, allow you to choose between the
various functions and options. However, unlike the Softkeys, the Hard keys are not dependent on the state of the telephone.
Any function or option can be enabled at any time utilizing the Hard keys. The hard keys include Function Hard keys:
MENU, FEATURES, DIR, CALC, F1 (Calendar) and HELP. All the other Hard keys operate as aids to the Function Hard
keys. The aids are used to configure and edit the options found in the Function Hard keys.

8VLQJWKH+DUGNH\V  *.78VHUV*XLGH
HARD KEY ACTION
SEARCH Opens a search window on top of the active function (FEATURES, DIRECTORY,
Calendar, …) display. Enter character string from the alphanumeric keyboard.
Pressing SEARCH ENTER (i.e., searching the null string) performs a search for
that string with the results appearing in alphabetical order. If the search results are
large enough to require more space than one screen can offer, use the Scroll Keys or
PG-UP & PG-DN keys to see the entire query. If the search operation does not find
any matching strings, the message - Item Not Found- is temporarily displayed
and the Graphic Display is restored to the point prior to where the search was
initiated.
The simplest way to conduct a search is to simply enter characters on the GKT
keyboard. The search window will automatically appear with the character string
already entered. Press ENTER to activate.
The other ways to conduct a search include:
•Press SEARCH and enter a character string. This looks for the character string at
the beginning of the words, even within word phrases,
e.g., Pressing SEARCH callENTER can find >'LYHUW&DOO@ and >&DOO:DLWLQJ@.
•SHIFTSEARCH - looks for the character string anywhere in the function being
searched (i.e., also in the middle of the “words”). E.g., pressing SHIFT
SEARCH QENTER can find >3DJH4XHXH@, as well as >:DNHXS5HTXHVW@.
•SEARCHSEARCH or SEARCH ENTER – Returns an alphabetical listing of
all the items in the current function.
GOTO Use to skip to another page in the same function. Press GOTO and enter the page
number you want to skip to.

HARD KEY ACTION
PRIVATE Displays the Private Directory records. The system prompts the user for a password
(if defined) to enter the directory. This is a toggle switch, therefore press PRIVATE
again to return to the Favorites List or general Directory.
NOTE! Define your PRIVATE Password in MENU>7RRONLW@>'LU@>6HW3ULYDWH3DVVZRUG@
Also, during an edit session, press PRIVATE to enter (or remove) the contact
information into the PRIVATE directory. Notice that on the orientation line the icon
changes. See Using the Private Directory on page 51 for more information.
DETAILS Changes the Directory function from the Brief mode to the Details mode where all
the details for the selected contact are displayed. Details are available for both DIR
and PRIVATE modes. Press ESC to return DIR. It is also possible to speed dial
from Details Mode. See also Using the Directory on page 37.
EDIT Edits the Directory file by adding, removing or updating entries. Also allows
accessing and manipulating the Favorites List. See Using the Directory on page 37
for more details.
LOCK This is a toggle switch that locks/unlocks the GKT so that it cannot initiate calls.
You can still receive calls. The user is prompted for a passcode to use this feature.
To change the Phone Lock passcode, press FEATURES. Search for Passcode. Enter
the old passcode (if defined – otherwise enter new passcode) from the dial pad.
Enter and re-enter new passcode until confirmed.
NOTE! This passcode (also used to operate other telephony features such as
EXECUTIVE PRIVILEGE and COS SWITCHOVER) is different from the Private
Directory password.
In Lock mode the Softkeys and Function Keys are not operational. A user trying to
operate the GKT will see the -PHONE LOCKED- message.
CAUTION! If you forget the passcode, you will not be able to unlock the GKT.
See your system administrator.

HARD KEY ACTION
SHIFT NOTE! The SHIFT hard key is the same as the SHIFT key on the keyboard.
Use the Shift key in combination with other keys for enhanced GKT functions such
as with HELP or SEARCH.
SHIFT is always pressed before the next key and not simultaneously with any other
key, allowing simple one-finger operation of the GKT.
Examples:
To print a capital Q, press SHIFT and then q, subsequent letters return to
lowercase. Use CAPS for all uppercase letters.
SHIFTHELP – Displays the Help Table of Contents.
SHIFTSEARCH – Finds character strings in the middle of the words.
Note! Press the SHIFT key, release it, and then the next key. The GKT ignores two
keys pressed simultaneously.

OPERATING THE GKT
Operating the GKT is as simple as pressing a button. The GKT options appear in the Graphic Display and
automatically change to reflect the current state of the telephone. Operate the GKT using a combination of Soft and
Hard keys.
Ten Softkeys, 5 located on each side of the Graphic Display, allow you to enable the relevant options as they appear.
The Softkey options change every time the GKT status changes.
The GKT Hard keys are located directly below the display. These are fixed GKT options that can be enabled at any
time, regardless of the GKT status. The Hard keys include Function keys such as: MENU, FEATURES, DIR
CALC, HELP and F1 (Calendar) and Function Aides: such as SEARCH, GOTO, EDIT, PG UP, PG DN. Use
the aides to configure and edit the Function options. See Using the Hard Keys (beginning on page 9) for more details
about the function aides.
Any GKT function can also be accessed by pressing MENU and then choosing the GKT Function by using one of
the Softkeys.
Use ESCto bring the GKT, one screen at a time, to the top level of the current Function. For example, when you are
changing a contact entry in Directory, continuously press ESCto return to the main screen for the Directory.
Pressing ESC however, does not switch between functions. To switch between functions, either use the Function
Hard key or use MENU.
