Getting Started
Checklist
Make sure the following items are in the box when you unpack it:
• Aluminium protective case for storing the GC75 and its antenna
• GC75 PC Card
• Antenna
• Quick Start Guide
•CD-ROM
The CD contains; drivers, software, documentation and a readme file
System Requirements
This section lists the network subscriptions, hardware and software requirements for running the GC75.
Network and Subscription
The network subscription you use in conjunction with your GC75 depends on the functions and features
your network operator can provide. Contact your network operator or service provider to make sure
the options you require are available. Make sure that data options are included in your subscription,
as these are usually optional services.
Note:
Mobile operators often provide a number of connectivity options via GPRS such as WAP and
Internet. Verify the service you require, such as Internet, email or corporate VPN (Virtual Private
Network) service is available through your mobile operator and enabled on your subscription.
The functionality of the different subscriptions available from networks operators are discussed below:
Circuit Switched Data (CSD)
CSD is the original GSM network data transfer method, used in the past for WAP. Almost all GSM
networks have this capability at 9.6 kbps. It is possible for the network to upgrade the speed to 14.4 kbps.
The GC75 operates at this higher speed where available.
High Speed Circuit Switched Data (HSCSD)
HSCSD is an enchanced GSM network capability offered by some network operators. It enables
circuit switched data connections to run at a higher data speed, using more than one wireless ‘timeslot’
for the data transmission. This is ideal for providing a faster connection to existing corporate or ISP
dial-up facilities. The preferred connection speed is selected when you define the connection using
the Connection Wizard.

8 Getting Started
General Packet Radio Service (GPRS)
GPRS is a type of network connection which provides “always on” mobility. The connection set up
is fast and, once connected, applications may send and receive data whenever required. In today’s
GPRS networks, the GC75 receives data at speeds up to 53.6 kbps and transmits at speeds up to
26.8 kbps.
Short Message Service (SMS)
The PC can send and receive SMS text messages using the SMS Messages screen in the Wireless
Manager, see Wireless Manager SMS Messages Screen on page 31, for more details.

When used with Establish GPRS connection at startup, this allows a GPRS session to be
automatically connected when the user logs on, see Example on page 18 for more details.
•Minimize when Windows starts
If enabled, the Wireless Manager starts when a user logs on to Windows, it appears as an icon
in the task bar only. If a GC75 is detected, the Wireless Manager runs and connects. If not, the
program closes (and runs in the background if permitted).
•Allow this program to run in the background
If enabled, the Wireless Manager runs in the background, waiting for a GC75 to be inserted.
When the card is detected, the Wireless Manager automatically opens and begins normal
operations.
When the close box, or File Exit is selected, the Wireless Manager closes but does not exit.
It releases control of the card, so it may be stopped and removed, and runs in the background.
You can start the program again from the Start menu, double-clicking the system tray icon, or
by re-inserting the GC75.
You can stop Wireless Manager running in the background by right clicking on the PC screen
and selecting Exit.
If you attempt to start Wireless Manager with no GC75 inserted a warning dialog is displayed,
informing you that the GC75 is not present, and Wireless Manager switches back to background
mode.
•Hide tray icon when no card inserted
If this option is selected, Wireless Manager runs in background mode, the Wireless Manager
icon is not displayed in the system tray. If the card is inserted, the icon reappears and the
Wireless Manager is started.
•Show menu item for Modem Software Update
If this option is checked, a File Modem Software Update... menu item is enabled. Selecting
this menu command prepares the modem to receive a software update from the Sony Ericsson
Update Service. More information about this service can be found at
http://www.sonyericsson.com.
