Important Battery Information

Safety Information

Sensitive Electronic Environment

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 SSW­1444 AC/DC adaptor in a wall outlet socket near the equipment for easy access/
removal of the AC/DC adaptor.

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, fire, 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 fire 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.

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
influence 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
influence 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 affixed to your product in order to
inform you that electrical and electronic products should not be disposed
of as municipal waste.

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
significant 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 fine 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.

About This Guide

Introduction

Introduction

The MBU 400 consists of a Mobility Base Unit (MBU) and the Aastra Digital
Enhanced Cordless Telephone 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 the 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 handsets can handle all calls for every line (IP calls and
PSTN calls). Your System Administrator can configure your phone via transfer of a
configuration file 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 overflow on the MBU.

Configuring Your Phone for First-Time Use

This section describes how to configure and set up your MBU 400 phone for first use.
If your MBU 400 System has been pre-configured by the Internet Telephony Service
Provider you purchased it from, the phone is ready for use once you have plugged in
all cables and connected the power. You can customize your phone using the
information provided in Customizing Your Phone on page 30.

The MBU 400 phone functions much like an ordinary analog telephone. However,
because it is connected to the Internet, you have to configure your phone before it is
ready for first use. The initial configuration may have already been done for you by
your System Administrator.

Making and Answering Calls

R

The MBU 400 System allows you to make both Internet and landline calls. Landline
calls are calls made over the Public Service Telephone Network (PSTN) just like a
regular phone. All outgoing calls (except emergency calls) are Internet calls by
default, unless you specify otherwise. All emergency calls default to the landline. (If
you don’t have a landline connected, you must change the emergency line setting. See

Changing Emergency Line Settings on page 41 for details.)

The following sections describe how to make and answer Internet, landline, and
intercom calls with the MBU 400 System.

VoIP Calls

To make internet calls on your Aastra MBU 400 phone, you must have registered an
account on the MBU system through either the handset, Web UI, or configuration file.
This may have been done for you by your System Administrator. If there are no VoIP
accounts in the system, you will not be able to make internet calls, and attempts to do

so will result in a red IP icon on the handset display. For more information see

Configuring the Phone Using the Handset on page 23, the Aastra MBU 400

All handsets connected to the same gateway can have a shared Call Log. You can
check whether your System Administrator has configured a "private" or "public" Call
Log, or use your handset to check your call log for calls received by other handsets.

The call log keeps track of all your incoming and outgoing calls. It consists of four
pages or screens that you can scroll through using the navigation keys on the handset,
including a page of all calls, and then lists by category. The following icons apply to
calls in the Call Log.

Missed calls

Incoming calls

Outgoing calls

The call log stores up to 30 numbers. For each call the call log keeps track of the
number, the date and time of the call, and the type of call: incoming, outgoing, or
missed. If the caller’s name and number is stored in the Contacts List, the caller’s
name displays. A number or name is only listed once, but all missed calls are counted
