Protective plastic case for storing the GC75 and its antenna GC75 PC Card SIM tray 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 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. 8 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 todays 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.

Additional Information 41 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. 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. Aircraft 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. 42 Additional Information Technical Specifications Product name GC75 System E-GSM 900 GSM 1800 GSM 1900 Services supported CSD, HSCSD, GPRS, SMS Speech services are not supported SIM Card Type Number Small plug-in card, 3V or 5V type SIM Lock supported 6130201-BV Exterior Description Size Weight Battery Antenna PC Card Type II, 16 bit 85.6 mm long x 54.0mm wide x 5.0 mm thick 38g including antenna, excluding SIM card Powered via the PC card slot i.e. uses laptop battery 50 ohm interface; Antenna supplied Ambient Temperatures Operating Storage 0 to 55 degrees C
