Call Forwarding

When you are not available to take calls or decide to answer your
calls on another extension, it is useful to forward your calls to an
alternate answering position. The alternate answering position can
either be a pre-programmed one ( a common one for: Fixed

Diversion, Diversion on no reply and Diversion on busy) or an

individual one.
If you urgently need to talk to someone who has forwarded his

calls, the system is also equipped with a bypass function.
Depending on the type of Diversion you are also able to record your

personal greeting, see section “Change your Personal Greeting” on
page 46.

Note: You can still make calls as usual.

Diversion on no reply

If you are not available to answer incoming calls (internal or

automatically divert calls to a programmed diversion address
(default time: 15 seconds).

Diversion on busy

If your extension is busy and you receive an incoming call (internal
or external), your system administrator can program your extension
to automatically divert the call to a programmed diversion address.

Networking

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 minimise 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:

B Press

*61* Pree

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.

Useful Hints

Useful Hints

Connections between external lines

With your BusinessPhone PBX, 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
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

• If you are connected to two external lines, cancel one call
by pressing “R” and “1”

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 re-programming your
system.

Please ask your system administrator or contact our service center
for more information.

Spread the clip slightly. The ends of the clip fit into holes on the side
of your phone.

Installation

Connect the adapter to the charger and connect it to the
mains outlet as shown in the figure below.

Notes:

Place the DT292 in the charger and charge it for at least 4
hours before using it the first time.

Make sure the local mains voltage corresponds to the
voltage on the charger.

Only use the charger that comes with the Cordless phone.

Do not connect the phone to the charger without a battery.

Place the Cordless phone in the charger to charge the
battery.

Complete charging before you subscribe or use the Cordless
phone. The green light of the charger is turned off when charging is
completed. For more information about charging the battery, see
section “Battery” on page 95.

DT29294

Installation

Battery

The Cordless phone is powered by a rechargeable battery. You can
fully charge an empty battery by placing the Cordless phone in the
charger for 4 hours. A fully charged battery gives you up to 17
hours calling time or up to 140 hours standby time.

Note: The calling time and standby time is shortened if the
hands-free speaking function is used a lot.

The Cordless phone has a battery meter, which indicates the
power remaining in the battery.

Note: The Cordless phone is powered by a Nickel Metal
Hydride (NiMH) battery. It can be recharged at any time. To
keep the battery fully charged, you can put or leave the
Cordless phone in the charger without any problem.

Reading the battery meter

When the battery is fully charged, the battery meter on the
Cordless phone display consists of four blocks. The number of
blocks decreases as the battery discharges. If the battery is almost
empty, the battery meter and the red light on the Cordless phone
flash. An alarm sounds if there is less than 15 minutes calling time
remaining in the battery.

Charging the battery

Place the Cordless phone in the charger as shown in the
figure below.

The battery is being charged when the lower green LED on the
charger is on (and the battery meter on the display flashes). If the
battery is completely empty it can take a few minutes before the
lower green LED on the charger is lit.

When the battery is 90% charged, the LED starts flashing (3
second intervals) and when the battery is fully charged, trickle
charging starts (LED lights up for 1 second every 30 seconds) and
the battery is ready.

Notes:

Place the DT292 in the charger and charge it for at least 4
hours before using it the first time.

Make sure the local mains voltage corresponds to the
voltage on the charger.

Only use the charger that is delivered with the Cordless
phone.

Do not connect the phone to the charger without a battery.

DT29296

Installation

Changing the battery

Rechargeable batteries have a limited lifespan. If the standby time
for the Cordless phone becomes too low, you should replace the
battery. Please contact your system administrator or supplier for
more information.

Note: Only use the specified batteries (NiMH pack 600
mAh, 3.6 V).

The battery does not contain cadmium and is therefore more
environmentally-friendly than other rechargeable batteries.
However, all batteries should be treated as chemical waste.

Clip

The Cordless phone has a clip to attach the phone to your clothes.

To attach the clip to the Cordless phone

See section “Preparing for use” on page 92 for specific instructions.

To remove the clip from the Cordless phone

Note: To minimize wear and tear, we recommend that you
do not remove the clip from the Cordless phone too often.

Remove the clip from the back of the phone as shown in the
