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.

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.

• A PC that has the minimum specification recommended by Microsoft to run the version of
Windows®installed on it.
