Safety information
Failure to observe this information can be hazardous and infringe existing laws.
Connections
Always plug the phone cable connectors into the appropriate sockets. Do not modify
the connections in any way.
Mains power
Use the original power supply only. Connect the power supply only to power sources
that conform to the indications on the power supply. The device will be inoperable
when mains power of the communication system fails.
Retention of Metal Objects
Telephone receivers produce magnetic fields that can attract small metallic objects such
as pins and staples.To avoid injury, do not place the handset where such objects can be
picked up.
Maintenance
Make sure all installation and repair work is carried out by a specially qualified techni-
cian.
Always use a soft, moistened, or antistatic cloth to clean your device. Do not use chem-
icals or other chemical products.
Cost control and Data protection
You should protect your phone with a PIN so that no-one can make phone calls at your
expense. A code will also protect your personal settings.
Ambient conditions
Do not operate the device outside the temperature range of +5 °C to approx. +40 °C.
Avoid direct sunlight and other sources of heat.
Protect your device against the wet, excessive dust, corrosive liquids and steam.
Do not expose your device to electromagnetic fields (electric motors, household appli-
ances).The speech quality could be affected.To prevent interference, avoid placing your
handset in the immediate vicinity of computers, radios, TV sets, VCRs, and other tele-
phone sets.
Disposal
Be sure to dispose of your device, batteries and its packaging in an environmentally
compatible way. Electrical equipment does not belong in domestic waste. Deposit it at
a return centre.

eud-1281/1.3 – R3.0 – 04.2013
Product information
Purpose and function
This product is part of the Aastra 400 communication solution.
Aastra 400 is an open, modular and comprehensive communication solution for the
business sector with several communication servers of different output and expan-
sion capacity, a comprehensive telephone portfolio and a multitude of expansions.
They include an application server for Unified Communications and multimedia ser-
vices, an FMC (Fixed Mobile Conversion) controller for integrating mobile phones, an
open interface for application developers and a multitude of expansion cards and
modules.
The business communication solution with all its components was developed to
cover in full the communication requirements of businesses and organisations, in a
way that is both easy to use and maintenance-friendly. The individual products and
components are coordinated and must not be used for other purposes or replaced by
third-party products or components (unless it is to connect other approved networks,
applications and telephones to the interfaces certified specially for that purpose).
One number user concept:
Your system administrator can set up several phones for you that hold all the same
phone number (one number user concept). You have only one name and phone num-
ber with which to identify yourself to your call partners, regardless of which of the
phone you make your calls. The advantage is that you can always be reached under
the same phone number, regardless of where you happen to be.
With Personal call routing you can define where incoming calls shall be routed to (see
chapter "Activating personal call routing", page 70). You can determine the phone on
which a call is acoustically signalled, with Ring Alone (see chapter "Activating ring
alone", page 70). Your system administrator can set whether or not you are busy for
further incoming calls (Busy if busy). You are still able to make further outgoing calls
with the other terminals.
Call lists and contacts are available on all your phones and are automatically synchro-
nised.
An announcement is signalled on all your phones which support announcement.
