Congratulations for purchasing the ISDN Deskmaster .
Regardless whether you use this ISDN phone in private or
business environment, it will always offer outstanding phone
comfort and will support you to intelligently administrate and
control your phone calls.
One of the main features of the phone is the logically struc-
tured user guidance and the adaptability to your personal
phone usage requirements. The Deskmaster’s display will
inform you about the actual operation mode and simplifies
the usage with menu keys of which the assigned functions are

The Deskmaster 520i with the integrated analog port (a sep-
arate product configuration) offers the connection of standard
analog terminals to the ISDN Deskmaster, such as an analog
phone, a G3 fax terminal or a cordless telephone with base
station.

phone, in order to learn about the whole set of features and
potential usages.

Cleaning
The phone can be cleaned without any problem. Please ensure the following:
• Wipe the phone with a damp cloth or use antistatic material.
•Never use a dry cloth for cleaning.
(Static electricity may lead to electronic defects.)
Please take care that no liquid gets inside the equipment (switches and contacts may be
damaged).
Disconnecting the Line Cord(s) from the Phone
•Press the lock towards the plug.
•Simultaneously pull the plug at the cord out of the telephone.
Note
The same procedure is also applicable for the analog port cable.
3
Place
For the placement of your phone, please ensure:
•Do not place the phone in an area where it may come into contact with water and chem-
icals.
•Plastic support pads of the phone:
The equipment has been manufactured for usage in normal environments. Chemical
influences from the area, in which you place the phone (chemicals used for the mainte-
nance of furniture) may have an impact on the plastic pads. This may then result in
unwanted damage to the furniture surface.
In the environment of new or refreshed furniture, we therefore suggest you to place the
phone on a nonskid mat (cloth etc.).
• Hands free speaking:
The hands free facility enables communication with the handset on hook. Other persons
in the room may then participate in the phone call. In order to achieve best hands free
quality, please mind the following:
The environment of the phone should not be covered by subjects such as piles of paper,
coffee pots etc.
It is suggested to ensure a free area of at least 15 cm at the front right part of the phone.
Security Notes
The ISDN Deskmaster has been manufactured in accordance with EN60950 :1992. The
adaptor supplied with the analog port version is also in accordance with EN60950.
The plug may only be operated at 230V mains supply. Please verify that the isolation of the
adaptor is neither damaged nor defective.
Attention
During operation, dangerous voltages may be generated in the phone. Do not
try to open the phone. The phone contains no parts, which could be repaired
by the customer. The supplier does not assume any liability for usages outside
the warranty and safety regulations.

•Another method to quickly access a menu is by searching the function by name. As all
menus within a menu level are arranged in alphabetical order, they can be accessed by
typing the first character of the function name required:
Note
Sometimes, the information available for the display may be longer than a dis-
play line (e.g. UUS messages etc.). This will be indicated by arrow symbols
() at the end of the display line. The remaining text can be viewed (horizon-
ally scrolled) by holding longer than 3 seconds the right (or left) arrow key
below the display.
When the visual indicators (LEDs) for unanswered calls ( sign) or programmed feature
information ( sign) are lit, the corresponding function
keys (left to the dialing keypad) can be pressed to display the information. Any further
action may then be completed using the menu control keys below the display as described
above.
The following sections describe the available functions and menus in more detail and
explain you how to navigate through the menu system.
See Appendix “Menu/Function Overview” for a list of menus and functions.

USER INTERFACE CONCEPT
The ISDN Deskmaster implements a few mechanisms to simply control the phone:
•All information is displayed in the 2 lines by 20 characters display. In addition, 2 LEDs
indicate the presence of unanswered calls ( sign) and programmed features ( sign).
•Below the display, 5 function keys are allocated to control the phone through the dis-
play guidance:
• The “ ” and “ ” keys will navigate through the menu structure. Always one menu
will be displayed at a time.
• The “OK ” key will select the function offered by the menu or open a submenu level,
if available. A submenu is indicated by the “ ” sign immediately following the func-
tion name.
• The “ESC” key will leave the current menu level or function without performing any
commands and return to the previous level.
• The key will provide direct access to the built-in phone book.
For users already familiar with the features of the phone, direct menu access mechanisms
are provided:
•Each menu item (function) is displayed with a 3 digit function code in front of the func-
tion name (display of function codes can be switched off). The menu/function can be
directly accessed by pressing the Function key “ ” (left side of the dialing keypad), fol-
lowed by the function code required, entered from the dialing keypad:
e.g.: 2 1 0

Call Log
Incoming calls, which have not been answered, will be recorded in a call log of unanswered
calls together with:
• Caller ID;
•Date and Time of the (last) call;
•Number of calls from that subscriber;
• UUS texts (if any).
There are 20 records available for that function. If all records are occupied, the oldest entry
will be overwritten.
If the same subscriber tried to reach you several times, the display will indicate the num-
ber of call attempts, but only the date and time of the most recent call attempt.
The call list LED to the left of the display (envelope sign) will start flashing, as soon as an
unanswered call has been registered.
With subsequent keystrokes on the call list key (left to the keypad, envelope sign), the reg-
ister entries can be scrolled. If you lift the handset off hook or press the hands free key,
the displayed caller ID will be called back.
The entry will be deleted from the register automatically, as soon as a connection has been
established. The selected entry can be deleted manually using the RIGHT arrow key to go
to the delete menu.

the Call List LED flashes.
