High levels of radio frequency radiation are considered health hazardous. Although no single value of
“safe radiation level” has been agreed upon by all
countries, the American National Standards Institute
(ANSI/LEEE C95.1-1992) recommends that people
should not be exposed to radiation stronger than
1 milliwatt per square centimetre at the frequencies
used in the SIMRAD MS50 terminal. Accordingly, the
RADIO FREQUENCY RADIATION
HAZARD - KEEP CLEAR
1 METRE MINIMUM
operator of the terminal should ensure that the area
extending 1 metre from the front of the antenna be
kept clear of personnel when the terminal is transmitting.
OBTAINING LICENSING FOR INMARSAT TERMINALS
Under rights given under ITU Radio Regulations, local telecommunications
administrations establish and enforce national rules and regulations governing
types of emissions, power levels, and other parameters that effect the purity of
signal, which may be radiated in the various frequency bands of the radio spectrum.
To legally operate an Inmarsat terminal, it is necessary to obtain permission from
the local telecommunications regulatory authorities of the country you are operating within. Using your terminal in any country without permission causes you to
run the risk of confiscation of the terminal or legal action from local authorities.
Normal practice for taking telecommunications into another country is to apply for
a license before travel. If a license has not been obtained before travel, the
equipment may be put into storage by local authorities until such time as a license is obtained.
All specifications are subject to change without notice.

• Phone book
• Manual selection of satellite Ocean Region
• Selection of default Net service provider
See chapter 2. Operation
Simrad MS50 may be delivered with an ordinary DTMF telephone for
basic voice communication.
A cordless base station or PABX can be delivered as option.
The SIM card (Subscriber Identity Module) carries subscription information from your Inmarsat Service Provider (ISP) or Net service provider on
an integrated circuit. The Simrad MS50 used with the SIM card assumes
the identity of the SIM card.
The SIM card has its own set of numbers on which the user can be
contacted irrespective of the Simrad MS50 used. All outgoing calls will be
billed to the owner of the SIM card.
The SIM card is protected by means of a lock code. When buying a
SIM card you will receive a Personal Identification Number (PIN) that
will contain up to 8 digits. Contact your dealer if you do not have your
PIN code.
If the PIN code entered does not match the PIN code on the SIM
card, operation with that particular SIM card will lock-up after three
failed attempts.
You must then use the SIM un-block code (PUK code) provided by
your ISP to un-lock the card. Contact your dealer if you do not have
the PUK code.
Note! When using the PUK, the SIM PIN is set to 1 2 3 4.
For procedures on how to change or disable the PIN code, see
"User access" in chapter 4. Data service.
Simrad MS50 – Chapter 1. Introduction1.4
The SIM card can store miscellaneous information, f.ex.:
• PIN code (Personal Identification Number)
• Last number list (previously called numbers)
• Phone book
• Allowed and preferred Net service providers
Note! When using SIM card, the accessibility of the functions described in this manual will depend on the card supplier.
Telefax service
The Telefax facility supports Group 3 fax transmission at a rate of
2.4 Kbps. The telefax is assigned a separate incoming call number.
see chapter 3. Telefax service.
Data service
A PC can be connected for individual setup and operation of all
functions of Simrad MS50, see chapter 4. Data Service.
The PC also allows the use of the built in Data Transmission Serv-
ice without the aid of a modem or data card, see chapter 4. Data
service.
The Asynchronous Data (ASD) system provides 2.4 Kbps data transfer between two Simrad MS50s, or between a Simrad MS50 and the
fixed international network.
The Data Transmission Service is assigned a separate incoming call
number.

Mail service
With PC connected to Simrad MS50, the Internet Messages Service
(NIMS) allows a message of maximum 1024 characters to be sent to

System satellites
The satellites are positioned in
a geostationary orbit above
the equator at approximately 35700 km
altitude.
See figure 1.3.
In geostationary orbit,
each satellite moves at
the same rate as the
earth, and so remains
in the same relative
position to the earth.
The satellites cover approximately 1/4 of the earth
each, called Ocean Regions:
AOR-W Atlantic Ocean West Region

Public
Telephone
Network
To make an outgoing call, you use a standard international telephone
number with the 00 prefix. The mobile automatically includes information to identify the MES and the particular port that originates the call.
Simrad MS50 has four ports configured for: display handset, telephone, telefax and data.
The LES uses the port identifying information (OI) for billing purposes.
The mobile transmits the dialing information on a channel specially
assigned by the NCS, to the LES, which also has been instructed to
tune to the same channel. LES routes the call over the public telecommunications networks to the intended destination. When the
called party responds, the call proceeds.
Calls to Mobiles
The Simrad MS50 terminal receives incoming calls via the IMN phone
numbers. IMN numbers are assigned to the following ports:
Calls are made as ordinary international (Satellite) calls where each
Ocean Region has an international country code. If an area is covered by more than one satellite, it is necessary that the caller knows
which satellite (Ocean Region) the mobile is tuned to, or if not known
try the other satellite(s).
The international codes to the four Ocean Regions are as follows:
Note! Some Net service providers support the common Ocean Region access no. 870, which connects the call to the dialed Simrad
MS50 regardless of the Ocean Region the user currently communicates through.
