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 equipment for easy access/removal of the AC/DC adaptor.
Important Battery Information
Safety 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 situation. 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.
x MBU 400 Installation Guide
Electrical and electronic products including the cables, plugs and accessories should be disposed of separately in order to allow proper treatment,
recovery and recycling. These products should be taken to a designated facility where the best available treatment, recovery and recycling techniques
are available. Separate disposal has signicant advantages: valuable materials 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.
