GD8000 User Guide Making Connections This section describes how to connect peripherals and hardware options that help you maximize your computer's features. Before connecting peripherals, first read the manual included with the peripheral for connection and operation instructions. You can purchase most of these and other options directly from authorized dealers. If you are a mobile worker, you may want to purchase an approved docking solution such as the Vehicle Dock or Office Dock. These docks provide drop-in convenience, port expansion, and automatic battery recharging, enabling you to leverage your computer's features without having to attach and reattach cables and connectors when you move your computer from office to vehicle. Attaching Power Your computer can be powered by battery, by attaching an AC Adapter or Vehicle Adapter to the DC power port, or by connecting the computer to a powered Vehicle Dock or Office Dock. NOTE When external power is properly applied, the External Power LED lights. CAUTION This notebook computer is designed to be used with the provided dedicated AC Adapter or Vehicle Adapter. To Attach AC Power 1. Connect the AC adapter power cord to the AC adapter. 2. Connect the AC adapter to the DC power port on the left side of your computer. 3. Connect the AC adapter power cord to a properly grounded AC outlet. NOTE It is recommended you use a quality surge protector. To Use the Vehicle Adapter (optional) 1. Insert the vehicle adapter's power cord into the DC-in jack on the left side of the computer. 2. Insert the 12V (cigarette lighter) adapter into the vehicle's 12V socket, turning it slightly to make a good connection. CAUTION The vehicle adapter is not intended to be used continuously. It is intended to provide a convenient, temporary power source for powering and charging this computer while in transit in a vehicle. For permanent installations, it is recommended that the (fused) vehicle charger adapter be wired directly to the vehicle power supply. For additional information regarding permanent installation, contact your sales representative. 3. The power LED illuminates to indicate that current is reaching the vehicle adapter. When you connect the vehicle adapter, it automatically begins charging the computer's battery. At moderate temperatures, around 20°C (68ºF), the battery should charge from empty to 90% in less than three hours if the unit is suspended or off. It should take less than four hours if the unit is in use. NOTE As the battery temperature approaches the ends of its temperature range (5°C/ 41°F to 50°C/122°F), it may take longer to charge the battery. CAUTION Avoid exposing batteries to extremely hot or cold temperatures for long periods. To prevent possible damage to the battery, the GD8000 laptop does not allow the battery to charge if the internal temperature of the battery gets too low (< 5°C or < 41°F) or too high (> 50°C or > 122°F). USB Devices Your computer comes with three Universal Serial Bus (USB) 2.0 ports on the right side of the computer. This enables you to attach various devices such as a keyboard, mouse, scanner, or printer. USB devices can be chained together on a single cable. External keyboard or pointing device This computer has a keyboard with full-sized keys and an embedded numeric keypad. If you feel more comfortable using a desktop keyboard, you can connect a USB external keyboard to one of the USB ports. You can also connect a USB mouse or other pointing device to one of the USB ports. General Dynamics Itronix | 72-0137-003 USB Ports
