Introduction

Congratulations and thank you for buying a Sony Ericsson GC75. GC75s are standard size type II
PC cards, they enable laptop users to have mobile access to the internet or corporate network with
flexibility and high speed, including ‘always online’ capability via GPRS. The GC75 is very simple
to install and use; the software provided allows you to select the best data service available so that
the GC75 is always available for data transfer.

The GC75 enables your laptop PC to:

• Browse the Internet

• Send and receive e-mails

• Receive information services in real time

• Access files, databases and discussion groups

• Send and receive SMS text messages

• Edit SIM card entries

Note:

Before using your GC75 you MUST read Guidelines for Safe and Efficient Use on page 45.

Hardware Overview

The GC75 is a standard type II Cardbus PC card. The card is standard length and only the antenna
protrudes outside the PC card slot.

The amount of power drawn from the laptop battery is dependant upon a number of factors including
status, distance to the base station and number of timeslots used. See Technical Specifications on
page 48 for a general guide to power consumption.

Before using the GC75, you must install the software on your computer and assemble the
components packaged with the phone, see GC75 Hardware Set Up on page 9.

SIM Card

When you subscribe to a mobile network operator, you are issued with a SIM card (Subscriber
Identity Module card). The SIM contains your personal subscriber data. You need to insert a SIM
into your GC75 before it will work.

Introduction 5

6 Introduction

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.

Getting Started 7

Hardware

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.

You will need:

• A PC that has the minimum specification recommended by Microsoft to run the version of
Windows

®

installed on it.

• A 16 bit type II PC Card slot.

• A Sony Ericsson GC75.

• A SIM card.

Software

You will need:

•Windows

®

98SE, Me, 2000 (SP4) or XP.

SMS Cell Broadcast message types are network operator specific. Contact your network
operator for more details.

This screen also allows you to set a validity period for the SMS messages that you are sending. For
example, if a message you send cannot be delivered because the recipient doesn't have their phone
on, the validity period sets a time limit on how long the service center should keep attempting delivery.

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.

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.

by re-inserting the GC75.
You can stop Wireless Manager running in the background by right clicking on the PC screen
and selecting Exit.

informing you that the GC75 is not present, and Wireless Manager switches back to background
mode.

• Hide tray icon when no card inserted

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

Parameters on page 61, for descriptions of the updateable parameters in the Advanced dialog.
The Secondary APN information is only used in special customised cases where the information
will be filled in for you. Otherwise the tick-box must be left un-ticked and secondary APN name
blank. Click Apply to save any changes before closing the dialog. Click Next.

7. If the operator you have selected in step 4 does not require a User ID and Password leave this
dialog blank if it is displayed. If you have to logon to your service provider, enter you User ID
and Password into the specific fields. If you want to enter your User ID and Password every
time you connect tick the box provided. Click Next.

Note:

Some versions of Windows® deliberately change the number of asterisks that represent a
