Introduction

Congratulations and thank you for buying the Sony Ericsson GPRS PC Card
Modem GC75.The GC75 is a triple band GSM product that enables you to
communicate wirelessly from your laptop on all five continents, in over one
hundred and sixty countries. As the GC75 provides wireless communications you

? Edit SIM card entries

Hardware Overview

The GC75 is a standard 16 bit type II 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, frequency band,
distance to GSM base station and number of timeslots used. See Technical
Specifications on page 48 for a general guide to power consumption.

Before you can start using the GC75 you need to put the hardware together. You will
also need a SIM card.

Important Information

Please read this information before using your GC75.

Recommendations

? Always treat your product with care and keep it in a clean and dust-free place.
? Do not expose your product to liquid, moisture or humidity.
? Do not expose your product to extreme high or low temperatures.
? Do not expose your product to open flames or lit tobacco products.
? Do not drop, throw or try to bend your product.
? Do not paint your product.
? Do not attempt to disassemble your product. Only Sony Ericsson authorized personnel

should perform service.

? Do not remove the SIM

Antenna

Only use an antenna that has been specifically designed by Sony Ericsson for your GC75.Use
of unauthorized or modified antennas could damage your GC75.

Children

Do NOT allow children to play with your GC75. They could hurt themselves or others, or could
accidentally damage the GC75. Your GC75 may contain small parts that could be detached and
create a choking hazard.

Disposing of the Product

Your GC75 should not be placed in municipal waste. Please check local regulations for disposal
of electronic products.

23

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.
