Importantes mesures de sécurité
Certaines mesures de sécurité doivent être prises pendant l’utilisation de matérial
téléphonique an de réduire les risques d’incendie, de choc électrique et de bles-
sures. En voici quelquesunes:
1. Ne pas utiliser l’appareil près de l’eau, p.ex., près d’une baignoire, d’un
lavabo, d’un évier de cuisine, d’un bac à laver, dans un sous-sol humide ou
près d’une piscine.
2. Éviter d’utiliser le téléphone (sauf s’il s’agit d’un appareil sans l) pendant
un orage électrique. Ceci peut présenter un risque de choc électrique causé
par la foudre.
3. Ne pas utiliser l’appareil téléphonique pour signaler une fuite de gaz s’il
est situé près de la fuite.
4. Utiliser seulement le cordon d’alimentation et le type de piles indiqués
dans ce manuel. Ne pas jeter les piles dans le feu: elles peuvent exploser.
Se conformer aux règlements pertinents quant à l’élimination des piles.
5. La socklet-sortie sera installée près de l’équipement et serafacilement

the total RENs, contact the telephone company to determine the maximum
REN for the calling area.
This equipment cannot be used on the telephone company-provided coin
service. Connection to Party Line Service is subject to State Tariffs.
If this equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of
service may be required. If such advance notice is not practicable, the
telephone company will notify the customer as soon as possible. Also, you
will be advise d of your right to le a complaint with the FCC if you believe
this is necessary.

For Industry Canada:‘’This product meets the applicable Industry Canada
technical specications.”
Before installing this equipment, users should ensure that it is permissible
to be connected to the facilities of the local telecommunications company.
The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated with a
single line individual service may be extended by means of a certied con-
nector assembly (telephone extension cord). The customer should be aware
that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certied equipment should be made by an authorized Canadian
maintenance facility designated by the supplier. Any repairs or alterations
made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines and internal metallic water
pipe system, if present, are connected together. This precaution may be
particularly important in rural areas.
viii MBU 400 Installation Guide
CAUTION: Users should not attempt to make such connections
themselves, but should contact the appropriate electric inspection
authority, or electrician, as appropriate.
‘’The Ringer Equivalence Number is an indication of the maximum number
of terminals allowed to be connected to a telephone interface. The termina-
tion on an interface may consist of any combination of devices subject only
to the requirement that the sum of the Ringer Equivalence Numbers of all
the devices does not exceed ve.’’
Le présent materiel est conforme aux specications techniques applicables
d’Industrie Canada. L’indice d’équivalence de la sonnerie (IES) sert à
indiquer le nombre maximal de terminaux qui peuvent être raccordés à une
interface téléphonique. La terminaison d’une interface peut consister en une
combinaison quelconque de dispositifs, à la seule condition que la somme
d’indices d’équivalence de la sonnerie de tous les dispositifs n’excède
pas 5.

Safety Information
Safety Information
Important Safety Information
Charge the battery or handset only in combination with 420d Charger and
the SALOM SSW-1444 adapter that comes with the product. Plug the
SALOM SSW-1444 AC/DC adaptor in a wall outlet socket near the equip-
ment for easy access/removal of the AC/DC adaptor.
Important Battery Information
This product uses rechargeable Lithium-ion batteries 3.7V, 650mAh. Only
use batteries that come with the handset or dedicated spare batteries marked
with “Battery Pack 3.7V 650mAh Li-ion”. Do not use any other type, since
this may present a risk of leakage, re, explosion or other hazardous situa-
tion. For battery replacement or removal please remove the battery cover of
the handset. Never disassemble, customize or short-circuit batteries. Do not
place battery in re or heat the battery. Charge the battery or handset only
in combination with 420d Charger and the SALOM SSW-1444 adapter that
comes with the product.
Sensitive Electronic Environment
Any radio-based equipment can potentially cause interference with other
equipment and can be interfered from other equipment. This also applies for
DECT equipment. However due to the very low transmission power level
the chances for interference are very small. Research proves that operational
DECT phones normally don’t inuence electronic equipment however some
precautions must be taken into account for sensitive electronic equipment
e.g. sensitive laboratory equipment. When DECT phones operate in straight
nearness of sensitive electronic equipment incidental inuence can appear.
You are advised not to place the DECT phone on or close (less than 10cm)
to this kind of equipment, even in standby mode. Please also use the other
documentation supplied with the various parts of your telephone system.
Product Disposal Information
For countries in the European Union
The symbol depicted here has been afxed to your product
in order to inform you that electrical and electronic products
should not be disposed of as municipal waste.
MBU 400 Installation Guide xi
Electrical and electronic products including the cables, plugs and acces-
sories should be disposed of separately in order to allow proper treatment,
recovery and recycling. These products should be taken to a designated fa-
cility where the best available treatment, recovery and recycling techniques
are available. Separate disposal has signicant advantages: valuable materi-
als can be re-used and it prevents the dispersion of unwanted substances
into the municipal waste stream. This contributes to the protection of human
health and the environment.
Please be informed that a ne may be imposed for illegal disposal of
electrical and electronic products via the general municipal waste stream.
In order to facilitate separate disposal and environmentally sound recycling,
arrangements have been made for local collection and recycling. In case
your electrical and electronic products need to be disposed of please refer
to your supplier or the contractual agreements that your company has made
upon acquisition of these products.
For countries outside the European Union
Disposal of electrical and electronic products in countries outside the
European Union should be done in line with the local regulations. If no
arrangement has been made with Aastra or your supplier, please contact the
local authorities for further information.
Battery Disposal Information
Defect or exhausted batteries should never be disposed of as municipal
waste. Return old batteries to the battery supplier, a licensed battery dealer
or a designated collection facility. Do not incinerate batteries.

Congratulations!
And thank you for choosing Aastra Telecom’s MBU 400.
The MBU 400 consists of a Mobility Base Unit (MBU) and the Aastra
Digital Enhanced Cordless Telephone (DECT) handset (420d) that provide
telephony service over the Internet and over the Public Service Telephone
Network (PSTN) or landlines. You can install the MBU on a desktop or on a
wall, while the 420d handset sits in its charging cradle on a desktop. You can
register up to 8 handsets with the MBU. The MBU supports up to 3 SIP calls
and 1 PSTN call simultaneously.
You can setup your MBU 400 in your business or home environment to act
as a small hub with group calling, voicemail, individual SIP accounts, or SIP
lines shared across a group. Once installed, the handset(s) can handle all
calls for every line (IP calls and PSTN calls). Your System Administrator can
congure your phone via a le transfer of a conguration le over TFTP or
HTTP, a local web interface, or the handset user interface.
The MBU can be connected to the Internet (service provider required)
via an Ethernet cable connected to the LAN port, and/or the PSTN via a
regular telephone cable connected to the LINE (or landline) port. The LINE
connection also allows for emergency calling and provides the handling of
call overow on the MBU.
Congratulations!
