This section describes the information that is important to know
before you use the DT292 phone, battery, charger and the
functions described.

Note: This User guide describes the supported BusinessPhone
Communication Platform functions together with the most
commonly used phone specific functions. All phone specific
functions are listed in the menu structure., see section “Menu

structure” on page 19.

Before using the DT292 the first time you have to charge and

Guidelines, warnings and precautions for safe and efficient use

Recommendations

• Always keep and handle your products with care and keep
them in a clean and dust-free place. Proper use and care will
prolong the products life. Use a soft absorbent tissue or cloth to
remove dust, dirt or moisture.

• Always ensure that the phone, battery and charger are used and
operated in the intended environment for which they are
designed.

• Operate the phone in temperatures between 0°C to +40°C
(32°F to 104°F).

• Do not expose your products to liquid, moisture, humidity,
solvents, strong sunlight, harsh environments or extreme
temperatures, never above +60°C (+140°F).

BusinessPhone – Cordless phone DT2926

Important

• Exposure to heat may cause batteries to leak, overheat or
explode, resulting in fire, burns or other injuries.

• Do not put the product in the microwave oven: This may cause
damage to either the oven or the product.

• Do not attempt to disassemble or alter any part of the phone,
the charger(s) or the battery-pack. Disassembly or alteration
may result in electrical shock or irreversible damage to the
equipment. Only a qualified service personnel or an authorized
Aastra partner should conduct internal inspections, alterations
and repairs.

• Do not expose your product to open flames or lit tobacco
products.

• Do not drop, throw or bend your products. This may cause
malfunction or electric shock.

• Do not paint your product.

• Do not use your product in an area where a potentially explosive
atmosphere exists.

• To avoid hearing impairment, accept the call before holding your
product (or portable handsfree device) to your ear.

• The DT292 phone is not specified as intrinsically safe, so do not
use it in areas with a danger of explosion.

Disposing of the product

• Your product should not be placed in municipal waste. Please
check local regulations for disposal of electronic products.

Power supply

• Connect the AC power adapter of the charging unit only to the
designated power sources as marked on the charger.

• Make sure the cord is positioned so that it will not be subjected
to damage or stress.

• To reduce risk of electrical shock, unplug the chargers from any
power source before attempting to clean or move it.

• The AC power adapters must not be used outdoors or in damp
areas.

• Never alter the cord or plug. If the plug will not fit into the outlet,
have a proper outlet installed by a qualified electrician.

• Limit the distance between the mains socket and the cordless
phone when charging for easy accessibility.

7BusinessPhone – Cordless phone DT292

Important

• As an energy saving measure, disconnect the charger from the
main socket after charging.

• When unplugging the mains adapter from the power outlet,
make sure that your hands are dry and ensure that you hold the
solid portion of the mains adapter.

• Do not pull on cables.

Charging and batteries

Please read carefully the following important precautions
before the first time use of the batteries. Make sure to
understand and observe all cautionary instructions stated, so
as to avoid any possible safety hazards that are caused by
any misuse, misapplication or damage to batteries.

• Only use batteries, mains adapters or desk and rack chargers
designed for use with your product.

• Use of power sources not explicitly recommended may lead to
overheating, reduced battery performance, distortion of the
equipment and fire or other damages.

• Cordless phones are equipped with Nickel Metal Hydride
(NiMH) batteries or Lithium Ion Lion batteries. In a complex
infrastructure, the talk- and standby time may differ, due to the
consequence of the increase in signaling.

• The battery must always be completely charged (minimal 4
hours) before first time use.

• The battery in your product is designed to withstand many
charge cycles.

• Use only the recommended charging equipment.

• Improper charging can cause heat damage or even high
pressure rupture.

• Observe proper charging polarity.

• Do not solder lead wires directly onto the battery.

• Do not apply water to the battery.

• The initial charging of a NiMH battery will cause the battery to
become warm. This is a normal effect of charging NiMH
batteries.

• The batteries are replaceable, however it is not the intention to
do this frequently.

• Only charge the batteries when placed in the phone.

• Use only the specified battery-packs for your product.

BusinessPhone – Cordless phone DT2928

Important

• Never heat or dispose of the battery into a fire, which, or else,
may cause leakage, burst or fire.

• Remove the carrying case from the product while in charger.

• Do not cover the product while being charged. Do not charge
the phone in a closed cabinet or drawer. The charging of the
battery is a chemical process and causes the battery to become
warm during charging. Make sure the environment in which the
phone is charged, is well vented.

• The cordless phone can be charged either when switched on or
off.

• Do not connect the battery's positive and negative leads
altogether in any case.

• Do not strike or drop the battery. It may cause damage to the
battery.

• Do not charge the battery under the temperature of +5°C
(+41°F). Be sure to charge the battery between the
temperatures of +5°C and +45°C (+41°F and 113°F). Charging
beyond these conditions may impair the battery performance
and shorten the life cycle.

• Do not use battery packs from different types, brands or of
different capacities.

• The battery is to be stored in a dry cool place, with the ambient
temperature around of +25°C (+77°F) for best performance.

• The battery continues to discharge a minimal portion of its
power, even if the product is switched off or the battery is
removed.

• Dispose the battery in accordance with all local regulations,
applicable in your country.

Warnings

• Smoke or fumes
Stop operating the products and turn off immediately in case of
smoke or fumes. Unplug the mains adapter and remove the
batteries from the phone immediately. Continued operation may
result in fire or electrical shock.

•LCD
If the liquid crystal display breaks, avoid injury by not letting the
liquid crystal touch the skin, getting it into the eye or into the
mouth or getting cut by the broken glass.

9BusinessPhone – Cordless phone DT292

Important

Preventing malfunction

• Never place the equipment in close proximity of electric motors,
welding equipment or other devices generating strong (electro)
magnetic fields. Exposure to strong (electro) magnetic fields
may cause malfunction and corrupt the communication.

• Moving the equipment rapidly between warm and cold
temperatures may cause condensation (water droplets) to form
on its internal and external surfaces. Water droplets may cause
malfunction of the equipment and corrupt or end
communication or damage the equipment. When condensation
is noticed, stop using the equipment. Switch off the phone,
remove the battery and unplug the mains adapter from the
power outlet. Wait until the moisture evaporates from the
equipment before putting it in operation again.

• Avoid accidental drop of the phone. Use the clip, security clip or
carrying case specified for carrying purposes of the phone.

• Avoid the phone being squeezed between furniture and your
body when carrying the phone in your pocket or attached to
clothing.

Call Forwarding

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 50.

Note: You can still make calls as usual.

Diversion on no reply

If you are not available to answer incoming calls (internal or
external), your system administrator can program your extension to
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.

Account Number

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.

The account numbers can also be used via the DISA function, see
section “Direct Inward System Access (DISA)” on page 66.

Tandem Configuration

SECOND USER
LOGGED ON

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 phone (the secondary telephone). Basically the
tandem configuration works as follows:

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.

Note: A s wi tc h to a n on -IP ca ll can only be perform ed if the
original call is an IP call, otherwise you will receive a blocking
tone.

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

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.

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.
