This manual describes the Capsat® Telephone.
The Capsat

®

Telephone is a mobile Inmarsat-phone mini-M terminal
which provides access to international telephone, facsimile and data
networks.

OMMUNICATION

OMMUNICATIONOMMUNICATION

OMMUNICATION

Operating the Capsat® Telephone is much the same as making direct
international telephone calls from an ordinary telephone.

The difference is that the Capsat

®

Telephone communicates directly
with a satellite and therefore does not rely on a local telephone
operator to route the call to the desired destination. Instead, the calls
to/from the satellite are routed by designated Land Earth Stations
(LESs) which also communicates with the same satellite as the
telephone terminal.

The necessary requirements to operate a satellite telephone is that
a) the terminal is registered by a service provider (i.e. payment

arrangements).

b) the location where the telephone is located is covered by a

satellite, and

c) there is a free line of sight from the antenna of the terminals to the

satellite.

The satellite system used by the Capsat

®

Telephone is operated by
the international organisation, Inmarsat. The system consists of four
satellites which combined guarantee world-wide coverage (see
appendix B for coverage maps).

When working with the Inmarsat-phone mini-M system, the following
abbreviations are often used:

Introduction

Page 1-2

12Oct01

MES Mobile Earth Station.

This is the name that Inmarsat uses for terminals.
E.g. the Capsat

®

Telephone is a MES. Mobile refers to the fact
that the terminals are re-locatable.
Earth Station is a satellite communication term.

LES Land Earth Station.

The LES is located at the "other" end of the MES's satellite link.
The LES connects to the local telephone networks and manages
calls to and from the MES.

NCS Network Co-ordination Station.

The NCS is responsible for assigning communication channels
to the MESs. In case of NCS failure the MESs will switch to
"Stand-Alone" mode. In Stand-Alone mode designated LESs in
each ocean region will act as NCS.

RECAUTIONS

The antenna unit radiates RF signals during a telephone call with the
strongest radiated signal on the focal line of the antenna and drops off
fairly quickly. Therefore allow a safety passage distance of 1 meter
around the antenna. Below is shown a safety guidance labels which
must be observed carefully.

Warning !

The TT-3007A Antenna radiates microwave signals.

Keep 1 meter of safety distance from the antenna

Proper handling of the Battery Pack is important to obtain maximum
talk and listen time. It is also a requirement for the warranty to cover
the Battery Pack.
To ensure proper handling follow the steps below:

I. Discharge the battery completely on regular basis, e.g. after 5 - 10

partial discharges. This will prevent the so called "memory effect"
in the battery cells which reduces their capacity.

I. Avoid exposing the Battery Pack to direct sunlight, as high

temperatures will reduce battery lifetime.

Installation

12Oct01 Page 2-3

I. In cold environment (0° Celsius and below) preheat the Battery

Pack if possible to e.g. body temperature before making calls. A
cold battery has less useful capacity than a warm battery (hence
longer talk time are obtained by preheating the battery).

I. Disconnect the small AC adapter when the Battery Pack is

completely recharged. Continuos over-charging of the Battery
Pack causes its temperature to rise. This will on the long term
damage the Battery Pack.

The procedure to discharge the Battery Pack is :
a) Disable the Telephone's sleep mode (see chapter 5).

a) Disconnect the Power Supply.
a) Leave the telephone on until the green POWER LED turns off.

When completely discharged then reconnect the Power Supply,
recharge the Battery Pack completely and re-enable the sleep mode.
If the Battery Pack continues to discharge rapidly, it may help to
repeat the discharge/recharge cycle an additional 2-5 times.
Refer to the Technical Reference in chapter 6 for more information on
battery handling and alternative power supplies.

The battery indicator in the handset display shows an estimate of the
remaining battery capacity.
The remaining capacity is estimated by monitoring battery over a
period of time. In sleep mode the battery is not monitored, therefore
the capacity estimate immediately after a sleep mode deactivation is
incorrect. The estimate will approach the correct value in
approximately one minute.

The TT-3060A's antenna (TT-3007A) resides naturally on top of the
Electronics Unit. It is kept in place by two vertical guide pins located
on the rear top of the electronics unit and is connected with a short
(0.15 m) antenna cable to the Electronics Unit.

Installation

Page 2-4

12Oct01

The antenna can be used directly on the Electronics Unit by rotating
the entire unit until its rear end points toward the satellite (the azimuth
angle) and then by opening the antenna (like a lid hinged on to the
rear of the unit), until it forms an angle with vertical equal to the
satellite elevation angle.
A detailed explanation for setting up the antenna will follow later.

With the long antenna cable the antenna can be placed up to 5 m from
the Electronics Unit. Before removing the antenna from the
Electronics Unit, the short antenna cable must be disconnected from
the antenna. It may otherwise be damaged.
On the bottom / back side of the antenna is a frame which serves as a
foot for the antenna when placed separately from the Electronics Unit.
The frame is hinged to the same tube which fits over the guide pins in
the Electronics Unit. When the antenna is mounted on the Electronics
Unit, the frame is fixed to the antenna by a small pin opposite the
tube. To open the frame it must first be released from the antenna by

lifting

it over the pin (see the following figures). Before the antenna
and frame can be tilted to the correct angle, the frame must be
opened until a 'click' is heard. How much the frame needs to be
opened before the 'click' depends on the angle of the antenna when
removed from the Electronics Unit: If the antenna is positioned
vertically when removed the 'click' should occur almost immediately,
if the antenna is positioned horizontally the frame needs to be opened
approximately 90° before the 'click'.

Once the satellite has been located, the antenna should be directed
towards the satellite.
Follow the directions below:

• Use the enclosed 5m antenna cable TT 37-104481 if you want to
place the antenna separate from the Electronics Unit.

• Find the selected Area on the antenna maps and read the
approximate azimuth (0-360 degrees) to the satellite from your
present geographical position.

• Turn the dial on the compass for the correct azimuth angle e.g. 40
degrees points to the arrow marked 'Read bearing here'.

• Turn the compass without changing the dial until the red needle
(North) coincides with the big arrow inside the compass dial
(Figure 2 -1).

• Now read the approximate elevation (0-90 degrees) to the
satellite from your present geographical position using the
antenna maps.

• The antenna can be tilted into any vertical angle. There are no
readings on the antenna for the elevation angle. When setting the
elevation angle start with the antenna in vertical position and then
tilt it the number of degrees equal to the elevation angle.
(Hint: The compass can aid finding the correct antenna angle

a) set the dial to the elevation angle
b) position the compass vertical with the "READ BEARING" arrow

pointing up

c) look at the parallel lines within the dial, they have the correct

angle.

The TT-3060A Capsat Mobile Telephone has three modes of
operations relating to its power consumption.

In the POWER OFF mode the terminal is turned off and no power is
used. In this mode the terminal will not detect any calls or messages
sent to it.

In the POWER ON mode the terminal is capable of making outgoing
calls and receiving incoming calls.
The power consumption is moderate to high depending on the state of
the terminal. Data and FAX calls consume more power than voice
calls. If no FAX or auxiliary telephone are connected to the mini-M
phone, the power consumption can be reduced further by disabling
the AUX/FAX interface completely

See the description of the configuration option in chapter 5.

Installation

12Oct01 Page 2-9

When the terminal is left unused for 60 seconds it will automatically
go into SLEEP-mode, unless the feature is disabled

1

.

SLEEP mode - In this mode the terminal will power up in short
intervals to check for incoming calls. The green POWER LED lights up
in short bursts. The transition to SLEEP-mode is made from POWER
ON either when commanded by the user with the LOCK command
(), or when the handset has been idle for 60 seconds duration.
The terminal returns to POWER ON mode if

a) an incoming call is detected, or

b) a key is pressed on the keypad.
In this mode outgoing calls cannot be initiated from the AUX PHONE
/FAX interface. The terminal must first be brought into POWER ON by
activating the handset.
