NOTICE: When taking the computer from low-temperature conditions into a warmer environment or from high-temperature conditions into a cooler environment, allow the computer to acclimate to room temperature before turning on power. • When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. As you pull out the connector, keep it evenly aligned to avoid bending any connector pins. Also, before you connect a cable make sure both connectors are correctly oriented and aligned. • Handle components with care. • Before you clean your computer, turn it off, unplug it from its power source, and remove the battery pack(s). • Clean your computer with a soft cloth dampened with water rather than with liquid or aerosol cleaners. • If the display or touch pad become smudged from use, they can be cleaned using a soft, clean cloth slightly dampened with water. Always turn off the computer before cleaning the display or touch pad.To clean the display, stroke the cloth across the display in one direction, moving from the top of the display to the bottom. To clean the touch pad, stroke the cloth gently across the surface of the touch pad. Do not allow water from the cloth to seep between the touch pad and the top cover of the computer. • If your computer gets wet or is damaged, follow the procedures described in "Troubleshooting Your Computer" in the User's Guide. If, after following these procedures, you confirm that your computer is not operating properly, contact Dell. (See "Getting Help" in the User's Guide for the appropriate telephone number.) Ergonomic Computing Habits CAUTION: Improper or prolonged keyboard use may result in injury. CAUTION: Viewing the display or external monitor screen for extended periods of time may result in eye strain. For comfort and efficiency, observe the following ergonomic guidelines when setting up and using your computer: • Position your computer directly in front of you as you work. • Adjust the tilt of the computer's display, its contrast and/or brightness settings, and the lighting around you (such as overhead lights, desk lamps, and the curtains or blinds on nearby windows) to minimize reflections and glare on the display. • When using an external monitor with your computer, set the monitor at a comfortable viewing distance (usually 510 to 610 millimeters [mm] [20 to 24 inches] from your eyes). Make sure the monitor screen is at eye level or slightly lower when you are sitting in front of the monitor. 1-6 Dell Latitude L400 System Information Guide
