System Requirements
This section lists the network subscriptions, hardware and software requirements for running the
GC75 PC Card.
Network and Subscription
The network subscription you use in conjunction with your GC75 depends on the subscriptions 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, so check that the Internet or VPN service you require is enabled for 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
General Packet Radio Service (GPRS)
GPRS is a new 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 GC75
Manager, see GC75 Manager SMS Messages Screen on page 33, for more details.
Hardware
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.
•

The home network.
•
Available networks, the name of the network is included in a list of preferred networks on your
SIM card, therefore, you can use the network.
•
Forbidden networks, you can’t use these networks except for emergency calls. If your home
network and a forbidden network come to an agreement that allows you to use the forbidden
network, you can select this network even though it is forbidden.

agreement between mobile operators for visiting users to use HSCSD. Check with your home
operator regarding the country or region in which you want to roam.
GPRS is commonly available in GSM networks, but fewer roaming agreements are in place.
You may therefore need to explicitly select one of the available networks in order to use GPRS
when abroad. Check with your home operator to find out which networks are GPRS roaming
partners in the country or region in which you want to roam.
Preferred (network)
A list of preferred networks is stored on the SIM card. This is typically set up by your mobile
operator as part of SIM manufacture. Preferred roaming partners are placed in the list so that you
have the greatest range of available services whilst roaming. When the home network is not
available, the GC75 will check the available networks against the preferred network list and select
the one placed highest. Automatic network selection must be enabled.
If you want to add a new network:
1. Click Add, a new dialog with all the networks known to the GC75 appears on the screen.
2. Select the network that you want to add and click OK.
3. Click Apply to transfer the setting to your GC75 SIM card.

Frequency Band
GSM operates in a number of different frequency bands. 900 and 1800 MHz are used in Europe,
Asia, Australasia and Africa, whilst the 1900 MHz band is used in North and South America. By
default your GC75 operates in 'tri-band' mode and automatically finds available networks in any of
these frequency bands. It is not recommended to change this setting. See GSM Performance and
technical characteristics on page 45 for a list of GSM frequency ranges.

Electronic Devices
Most modern electronic equipment, for example equipment in hospitals and cars, is shielded from
RF energy. However, certain electronic equipment is not, therefore:
Do not use your GC75 near medical equipment without requesting permission.
The GC75 may affect the operation of some implanted cardiac pacemakers and other medically
implanted equipment. Pacemaker patients should be aware that the use of a GC75 very close to a
pacemaker might cause the device to malfunction. Avoid placing the GC75 over the pacemaker. If a
minimum distance of 15 cm (6'' inches) is kept between the GC75 and the pacemaker, the risk of
interference is limited. If you have any reason to suspect that interference is taking place,
immediately turn off your GC75. Contact your cardiologist for more information.
If you use any other personal medical device, consult the manufacturer of your device to determine
if it is adequately shielded from external RF energy.
Turn your GC75 off in any facility where posted notices so require.
Aircraft
You MUST remove your GC75 before boarding any aircraft.
To prevent interference with communication systems and abide by the law, you must not use your
GC75 while the plane is in the air.
Do not use it on the ground without permission from the crew.
Blasting Areas
Turn off your GC75 when in a blasting area or in areas posted turn off two-way radio to avoid
interfering with blasting operations. Construction crews often use remote control RF devices to set
off explosives.
Explosive Atmospheres
Turn off your GC75 when in any area with a potentially explosive atmosphere. It is rare, but your
GC75 could generate sparks. Sparks in such areas could cause an explosion or fire resulting in bodily
injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They
include fuelling areas, below deck on boats, fuel or chemical transfer or storage facilities, and areas
where the air contains chemicals or particles, such as grain, dust, or metal powders.
Do not transport or store flammable gas, liquid, or explosives in the compartment of your vehicle,
which contains your GC75 and accessories.
Inserting and removing the SIM card – precautions against electrostatic discharge (ESD)
Do not touch the SIM card connectors. As a precaution, always make sure that the GC75 is already
in your hand before you insert or remove the SIM card.

FC
Before a modem is available for sale to the public, it must be tested and certified to the FCC that it
does not exceed the limit established by the government-adopted requirement for safe exposure. The
tests are performed in positions and locations as required by the FCC for each model. Body worn
measurements are made while the product is in use and worn on the body with an Sony Ericsson
accessory. The design and composition of an accessory can affect the body worn SAR (Specific
Absorption Rate) levels for the modem card. The distance used in the SAR Test Report for this
device is 4mm.
Sony Ericsson has not measured, and makes no representation about, the body worn SAR levels
when the modem card is used with non-Sony Ericsson accessories.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) The device must accept any
interference received, including interference that may cause undesired operation.

If you intend to create connections via CSD contact your network operator
and check the supported speeds.
HSCSD Network
Speed
If you intend to create connections via HSCSD contact your network
operator and check the supported speeds.
Username
The username your service provider gave you when the account was set

Password
Password associated with the username, given to you by the service
provider. Some dial-up accounts do not require a Password, in this case
leave the field blank.
IP assignment:
Server / Static
An ‘address’ that the service provider knows you by and uses to route
information to and from your GC75. Your IP address will either be:
Server - assigned by the service provider when you connect.
Static - assigned once by the service provider or the IT Manager.
If your IP address is Static you must enter it into Own IP address fields
which is available when you select Details in the Connection APN dialog.
DNS
assignment:
Server / Static
This tells the GC75 where to find the service provider’s DNS Service. DNS
translates addresses such as www.sonyericsson.com to the numeric IP
address so that the information can be accessed.
Like IP assignment above, the DNS can be static or allocated by the
service provider when you connect. If static is selected additional fields
need to be completed containing the static information.
Own IP address
Only required if the IP assignment is static.
Format example: 123.9.45.3. 
Do not enter any leading 0s when typing in IP address.
