TECHNICAL MANUAL
SAILOR SC4000 IRIDIUM
Introduction
Your Iridium equipment is a modular system that consists of a
transceiver unit, control handset unit, antenna unit and an optional
analogue PSTN telephone/PABX.
You can make and receive voice calls on the control handset and the
analogue PSTN telephone. You can connect up to four handsets
and one analogue PSTN telephone or PBX switchboard to the
system.
The system provides intercom for internal calls between any control
handsets and between the analogue telephone and a control
handset.
Via the data port on the transceiver, the unit can be used as a data
modem for dial-up data calls, Internet access, SMS and E-mail
messaging.
