The Cordless DT400, DT410 and DT420 are IP54 classified, which
means that they are not specified as intrinsically safe. Do not use
them in hazardous areas.
Only the DT430 is designed for environments requiring intrinsically
safe equipment and therefore IP64 and EX-classified.
Battery handling
The NiMH battery contains environmental polluting material. If
damaged, return it to a collecting point.
Note: Only use the charger that is delivered with your
Cordless to charge the battery.
Cleaning
Clean the Cordless only with a soft, water dampened cloth. Using
soap or any other cleaning materials may discolor or damage the
Cordless.
Tre at me nt
Although the Cordless telephones are resistant to water spray, dust
and soil, you should handle your phone always with care. Do not
expose the Cordless to direct sunlight for long periods and keep
your phone away from excessive heat.

When you are working together in a team the following group
facilities can be very useful.
Group hunting
Your telephone can be included in one or several hunt groups. In a
hunt group all members are represented with one common
directory number. 16 hunt groups can be programmed, each
containing 1 to 20 members. A member can be either an extension
number, an operator console or a fictive number. Please ask your
system administrator if you require this function.
T
Note: The number of cordless extensions in a hunt group is
limited to eight (including tandem configurations).
Incoming calls to the hunt group are directed to free extensions in
the group. The hunt order within the group can be changed to suit
your needs. If all members of the hunt group are busy an incoming
call is being queued. If no one answers an incoming call before the
programmed time, the call is forwarded to the programmed
answering position (e. g. operator).
Note: If all members in a hunt group are busy, the call-back
or intrusion functions are not available.
Log in
Before you can answer group hunting calls, you must log in.
To log in to one hunt group:
In a pick up group, any member can answer any individual call to
group members. You answer a call to a group member by dialling a
special answering number. Please ask your system administrator
for the configured number.
Press
Dial the group call pick up code
Ask your system administrator for the group call pick up code.
Common bell
The common bell facility allows all extensions of the system
(operator included) to pick up the call from an extension that has
been predefined as a common bell extension.
T
z
Press
Dial the common bell pick up code
Ask your system administrator for the common bell pick up code.
If two or more extensions simultaneously attempt to answer a call
from the common bell extension, only the first extension will pick it
up. The other extensions will receive the “number unobtainable”
tone. This will also happen if you dial the common bell pick up code
and there are no calls waiting at the common bell extension.
By using these facilities your productivity will be increased, e.g. you
can set reminders for important meetings, place the costs for
external calls on separate accounts and much more ...

The phone can be set to remind you at any time within the next 24
hours (multiple settings are allowed).

An account number can be entered to debit telephone costs to
different accounts. Depending on the system configuration the
account number has to be entered from a verified account number
list (predefined) or you can invent an own account number. The
following prerequisites apply:
•With the verified account number you can restrict the making of
external calls (not a specific number or area), so everyone who
is allowed to make external calls will receive an account number
which has to be used each time he/she wants to make an
external call.
•Verified account numbers contain up to 10 digits.
•Own account numbers contain up to 15 digits.

Tandem configuration
The tandem configuration is a unit, consisting of two telephones
using the same directory number. One of the telephones is defined
as the “Primary” and the other one as the “Secondary”.
This function enhances the communication for users that, for
example, have a wired phone on their desk (the “primary
telephone”) and need to be mobile within their company’s building
with their own Cordless (the “secondary telephone”). Basically the
tandem configuration works as follows:

If you are working externally and you have the need to make
business calls, call your company and use the company PBX to build
up an external call to the desired party. You just pay the costs for the
phone call to your company. The other costs will automatically be
placed on your extension number or on a special project.
Note: To activate this function, you have to change the
default password from “0000” to a personal one. Which
code to use and how to change it, see section “Select
password” on page 62.
You can also divert calls from your office extension to your external
position, see section “Call Forwarding” on page 23. During the

Networking is the connection of several premises within a
company. The connection can be set up via leased lines, public
lines, Local Area Network (LAN) or Wide Area Network (WAN). Ask
your system administrator about details regarding networking.
IP calls
IP calls are internal calls sent via an internal data network (LAN or
WAN) and the transfer of data and voice is made on the same line.
If you are connected to an internal data network the IP connection
is made automatically. To minimize the traffic on the network the
speech quality is decreased.
If the speech quality is not acceptable you can disconnect the IP
call and switch to a non-IP call (alternative network). The switch
from the IP net to the non-IP net is made during the call, so the call
does not have to be disconnected.
If you want to switch to a non-IP net during the call:
Q

Press
Dial
During the procedure the other party is put on hold. When the
procedure is ready you will receive a special ringing tone and the
call is resumed in the non-IP net.
Note: A switch to a non-IP call can only be performed if the
original call is an IP call, otherwise you will receive a blocking
tone.
You can lock your keypad to avoid accidental activation or dialling a

signal and ring melody. In addition to this there is a trembler, if your
system has that option.
Volume control
Use the volume keys to adjust the volume in the earpiece.

With your BusinessPhone Communication Platform, you can
establish an external call diversion or a conference with more than
one external party or transfer an external call to another external
destination (e.g. a mobile phone). These features are very useful for
everyday business life.
Note: When these features are used, your BusinessPhone
Communication Platform will occupy at least two external
lines.
However, there may be disadvantages in connecting to several
external lines. We would therefore like to draw your attention to the
following:
•Please do not transfer external calls to an external
mailbox, to information systems or to external parties
before they have answered
•Try to avoid diverting calls to third parties before they
have answered
•If you are connected to two external lines, cancel one call
by pressing the “R”-key and the “1”-key
If the external parties are not persons (mailbox, automated
information or attendant systems, etc.), connections on external
lines can last a long time, which can be costly. Moreover, such calls
may occupy two of your system’s external lines. You can restrict
connections between the external lines by reprogramming your
system.
Please ask your system administrator or contact our service centre
for more information.
This chapter describes how to connect and charge the battery of
your Cordless.
Note: If you are using the DT430 or another phone that was
equipped with an intrinsically safe battery for EXclassification, you need to loosen the screws at the back of
the phone, see “DT430” on page 90 in this section.
DT400 / DT410 / DT420
The DT400, DT410 and DT420 are supplied with a high capacity
nickel metal hydride (NiMH) battery. If you have more than one
battery available, you charge only the battery.
Removing the battery
To remove the battery, use the two plastic ribbed plates at the short
side of the Cordless.
Pull the plates towards the middle of the telephone
The DT430 telephone is designed for usage in rough environments.
This Cordless is safe to use in explosion risk environments (EXclassification) and therefore is equipped with a special battery.
Removing and fitting the battery for intrinsically safe
phones
To remove and fit the battery, you have to use the screws at the
back of your phone, as shown below. You do not have to use the
ordinary plates to release and fasten the battery.
Use the screws on the back of the battery
Screws to unlock or fasten
Battery performance
All Cordless are supplied with a high capacity nickel metal hydride
(NiMH) battery. The table below indicates the performance.
When the battery requires charging, you will hear an attention beep
and the display will show the “Low battery” icon.
Place the Cordless in the desktop charger as shown in the
figure below
The charging process will start automatically, indicated by a red
light on the charger. It takes approximately one hour to fully charge
the battery.

The handset is fully operational while stored in the desktop charger.
If you have another battery, you can also place just the battery
alone in the desktop charger.
When charging is complete, the charger light will turn green.
Notes:
Do not connect your Cordless to the charger without a
battery.
If the battery is completely flat it can take a few minutes
before the red light on the charger is lit.
If the standby time for your Cordless becomes too low, you
should replace the battery.
Only use the charger that is delivered with your Cordless to
charge the battery.
It is normal for the battery to get slightly warm while
charging.
All your personal settings in the handset are programmed and
stored in the Subscriber Identity Module (SIM) card.
The SIM card provides you with personal mobility as you can easily
move it to another Cordless telephone, enabling you to receive
calls, make calls and keep all your personal settings such as phone
book, identity and alert signal.
Changing the SIM Card
Note: Change the SIM Card only in an environment without
static electricity.
Remove the battery
See section “Removing the battery” on page 88. The SIM card is
placed under the battery unit in a hatch in the middle.
Move the steel plate forward to open the hatch
You see the labels “OPEN” and “LOCK” on the steel plate.
Push the steel plate carefully in one of the directions.
Lift the hatch and remove the SIM card
Now you can place it in another Cordless.
