The Optus MobileSat S2 is designed to work directly with the
Optus B-Series satellites that is geostationary over the equator,
North East o Australia.
There ore, or correct operation, there must be no physical
obstruction between your Optus MobileSat S2 antenna and the
satellite overhead. Generally speaking, the satellite is in the
north sky, in the direction o the sun, mid morning.
Possible reasons or an obstruction to a clear view o the
satellite:
• Bridges overhead
• Large trucks alongside
• Nearby buildings
• Inside buildings (unless the antenna is near a window rom
which you have line o sight to the satellite)
Medium tree cover does not prevent operation o the phone.
Your antenna should be adjusted correctly or the relevant
location in Australia. Re er to Map 1 on page 81, and the section
"Antenna Adjustment" or "Experiencing Problems" or more
details.
Use care in handling your phone, just as you would with your
home telephone.
• Do NOT leave your phone exposed to extreme environmental
conditions, such as high humidity, rain, high temperatures,
direct sunlight or dusty conditions.
• Do not clean with caustic or harsh chemicals.
The Optus MobileSat S2 has a rechargeable internal battery which
may latten i the transceiver is not connected to a power source
or an extended period.
For transceivers that are not permanently connected to a power
source (e.g. in storage or transportable case) Optus
recommends recharging the battery every three months.
Connect the transceiver to a power source or 48 hours every
three months o storage to keep the battery adequately charged.

The ollowing are instructions about Sa ety and Sa ety
Precautions when using your Optus MobileSat S2 telephone.
Failure to heed these sa ety instructions could result in serious
personal injury and possible property damage.
RADIO FREQUE CY I JURY (RADHAZ): Your phone is a power
transmitting device. When the phone is in use, radio requency
energy (RF) with a power output level o up to 4 watts radiates
rom the antenna. When the unit is transmitting, avoid close
contact with the antenna and/or close exposure to the radio
requency energy radiated rom the antenna. (Transmission
occurs when the telephone user is talking or sending data.)
EXPLOSIVES: Radio requency energy (RF) is a potential danger
near explosives. Turn o your phone when re uelling a vehicle or
when you are in areas o blasting operations or other hazardous
environments. ALWAYS OBEY ''Turn O Two Way Radio'' signs.
Use the phone key to turn o the power.
TRA SPORTI G EXPLOSIVES: Because o the danger o
explosion, NEVER store nor carry lammable gas and/or liquids
or explosive materials in the same compartment with your
satellite phone. Treat LP gas and containers as an explosive
unless correctly installed with ventilation or vehicle use.
MOBILE OPERATIO : Re rain rom using your phone while you
are driving a vehicle, even during hands- ree operation. When a
call is received or you make a call, PULL OFF THE ROAD AND
PARK. It is illegal in some locations to use mobile and radio
telephones while driving.
It is necessary to turn o the phone at Petrol/Service Stations to
eliminate the chance o inter erence or potentially dangerous
radio requency energy (RF) transmissions.
I JURY I VEHICLE: Secure the phone in your vehicle to prevent
damage to the phone and personal injury in the event o an
accident.

2 Wire Configuration
It is possible to connect a normal telephone to the Optus
MobileSat S2 TEL & FAX port to make and receive calls. This
includes a standard cordless phone. Due to the system protocol,
ISDN unctions and pulse metering ( or coin phones) are not
supported by Optus MobileSat S2 telephones. See Function 35 to
enable the TEL/FAX port.
To make a call
Li t the handset rom the phone and wait or a steady dial tone.
This dial tone indicates the phone is in Standby mode. Dial the
phone number using the phone’s keypad and press the Flash
button to indicate that no more digits are to be entered. Note
that a pre ix digit may be required be ore entering the
destination phone number (see page 71). I the Flash button is
not pressed, the Optus MobileSat S2 transceiver will wait a
short time be ore assuming the complete number has been
entered, and will then start the call setup with this phone
number. A beep tone indicates the start o the call connection.
I less than 3 digits are dialled, then the Optus MobileSat S2 will
not attempt to connect the call, but will produce a busy tone at
the handset a ter a timeout period. A ter 32 digits are dialled
every attempt to dial more digits will produce a beep tone at
the handset and the digit entry will be ignored.
The ring tone will then be heard to indicate connection. A
ailure to connect will result in a busy tone at the handset.

Placing a DATA Call
The Optus MobileSat S2 Satellite telephone incorporates its own
modem within the transceiver. This internal modem responds to
a restricted set o standard Hayes modem commands.
To send data using the Optus MobileSat S2 transceiver, it is
necesary to have a compatible data terminal which may connect
to the RS232 pins o the DATA & MAINTENANCE port.
A standard RS232 data communication cable is required to
connect the data terminal to the Optus MobileSat S2’s DATA &
MAINTENANCE port.
Configuring the DATA Terminal
Con igure the data terminal so tware package to have the
ollowing settings:
Connection: Direct to Com1 (or Com2, 3 or 4)
Baud Rate: 9600bps
Parity: None
Stop Bits: 1
Flow Control: Hardware
Recommended FTP: Zmodem
DATA Operation (sending)
The data call dialling is controlled by entering Hayes AT
commands at the data terminal. The Optus MobileSat S2 only
supports a restricted set o commands, re er to Table 4 on page
18 or this in ormation.
To initiate a data call, type ‘atdt’ ollowed by the ull STD number
o the destination you wish to dial.
For example: atdt0392643050
Call set-up time will be longer than or standard DATA
communications due to the added satellite delays. Once
connected, data can be sent. Optus recommends using the
“Zmodem” ile trans er protocol (FTP) because o its usability
and robustness.
17
FAX Call (Facsimile Machine)
To send a ax using the Optus MobileSat S2 transceiver, it is
necessary to have a compatible ax machine connected to the
TEL & FAX port o the transceiver.
A ax can be sent by ollowing the instructions (on sending a ax)
o the ax machine. The dialling o the destination number is
described in ‘Placing a Call: 2 Wire Con iguration’ on page 14,
and may require a pre ix digit.
The Optus MobileSat S2 transceiver operates transparently to the
ax machine. Once the ax machine has inished transmission,
the call will end automatically.
STD Area Code
An STD (or IDD) Area Code must be used or all ax
transmissions except or:
• Operator connected calls
• National numbers generally beginning with “1”
• 008, 013
The handset display will indicate that the transceiver is currently
being used in a ax call.
Fax sending may be restricted by phone locks o the phone, or i
the Optus MobileSat S2 has been con igured to have the ax
acility turned O .
ote: The TEL/FAX port o the Optus MobileSat S2 can be set to allow only
ax calls to be made. Re er to Con iguration Accessories on page 71.

During a data call, the handset display will indicate that the
transceiver is currently being used via the “Data Port in Use”
display. Re er to Table 3 below or a ull list o handset displays
during a data call.
Upon completion o your data trans er, the call can be hung up
by either typing the escape sequence ‘+++’ ollowed by ‘ath’, or
by dropping the DTR line (provided that the Optus MobileSat S2 is
con igured to monitor DTR status See page 20.) The call can also
be terminated through the handset by pressing the
keys.
The Optus MobileSat S2 behaves transparently to the data
terminal. Once the data terminal hangs up the call, the Optus
MobileSat S2 will cleardown the satellite channel.
