SAFETY INSTRUCTIONS
WARNING
Leave the equipment powered while
underway.
Distress cannot be communicated unless
the equipment is powered.
Wait at least 30 minutes after turning off
the power before entering the radome.
The gyro motor rotates for some time after
the power is turned off.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Turn off the power immediately if water
leaks into the equipment or the equip-
ment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.
Do not place liquid-filled containers on
the top of the equipment.
Fire or electrical shock can result if a liquid
spills into the equipment.
Do not approach the radome
closer than 6 meters when
it is transmitting.
The radome emits radio waves
which can be harmful to the
human body, particularly
the eyes.
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Do not operate the equipment with wet
hands.
Electrical shock can result.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
Any repair work must be done by a
licensed radio technician.
Improper repair work can cause electrical
shock or fire.
Use the proper fuse.
Fuse rating is shown on the equipment.
Use of a wrong fuse can result in damage
to the equipment.
WARNING

iv
CAUTION
Do not use the equipment for other than
its intended purpose.
Use of the equipment as a stepping stool,
for example, can result in personal injury
or equipment damage.
A warning label is attached to the
terminal, communication and antenna
units. Do not remove any label. If a label
is missing or damaged, contact a
FURUNO agent or dealer.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

1. INMARSAT-B SYSTEM
1.1 What is Inmarsat?
The International Maritime Satellite Organization (Inmarsat), founded in 1979, is
the international governing body for maritime satellite communication. Its purpose
is to provide global communications for ships, land mobile and aircraft, using
satellites to overcome the problems that exist with conventional radio
communications.
The Inmarsat system is made up of three major components: the space segment
provided by Inmarsat, the Land Earth Stations (LES) provided by Inmarsat
signatories, and Mobile Earth Stations (MES). The Operation Control Center
(OCC), located at Inmarsat headquarters in London, controls the overall system.
1.2 Geostationary Satellites
The type of satellites used for maritime communication are geostationary
satellites. Four satellites, one for each of four ocean regions, are placed in nearly
36,000 km-high 24-hour circular orbits rotating in synchronous with the earth,
providing mobile-to-land, land-to-mobile, and mobile-to-mobile communications.
The satellites remain fixed over a given place on the earth's equator, so an
Inmarsat subscriber is always within coverage of a satellite.
Speed: 11,070 km/h
Revolution: 23 hrs 56 min

1.3 Service Area
The Inmarsat system divides the world into four regions and each region is
covered by its own satellite. The regions are Atlantic Ocean Region-East (AOR-
E), Atlantic Ocean Region West (AOR-W), Pacific Ocean Region (POR), and
Indian Ocean Region (IOR). The reason for two regions in the Atlantic Ocean is
to solve the coverage gap problem there.

1.5 Inmarsat-B Services
The Inmarsat-B maritime satellite communication system provides digital
telephone (voice), facsimile, telex and data (9600 kbps) and HSD services. Use
of the latest digital technology means lower toll charges than in Inmarsat-A, since
high output power satellites are not required and data is transmitted at high
speed.
1.6 Comparison of Inmarsat Systems
Inmarsat provides worldwide communication services for both maritime and land
subscribers, and consists of four systems, A, B, C, M and Mini-M. The following
table shows the services available with each system.
