Voltage spikes caused by phenomena such as storms, transmission problems, and appliances can easily damage your computer. The Ergonomic Workspace An ergonomic workspace allows you to work efficiently and comfortably for longer periods of time. Here are some general ergonomic guidelines and recommendations to keep in mind when setting up your system: • Position your system so that the monitor and keyboard are directly in front of you. Contact your CTL Dealer or Representative if you need to order items such as keyboard shelves and monitor stands to aid in proper placement of the keyboard and monitor. • The monitor should be at a comfortable viewing distance, typically 20 to 24 inches. • The monitor screen should be at (or slightly below) eye level when you are sitting in front of it. • Adjust the monitor's brightness, contrast, color balance, and tilt as well as surrounding lamps and curtains to minimize reflections and glare on the screen. It is generally advisable to adjust the monitor's brightness as low as possible while still maintaining a clear view of the screen and its contents. You may also wish to purchase a glare guard. Please contact your CTL Dealer or Representative. -11 • • • Your forearms should be horizontal and wrists in a comfortable neutral position while typing or using the mouse. • There should be space to rest your hands on your desk while using the keyboard/mouse. • Allow your upper arms to hang naturally at your sides. • Sit erect, keeping your feet flat on the floor and your thighs level. • Make sure your feet are supporting the weight of your legs and not the front edge of your seat. Adjust your seat and/or use a footrest to maintain proper posture. • Vary your work activities or, if this is impossible, take frequent short breaks to stretch your arms and legs, focus on objects at varying distances, and relax. Electrical Outlets Computers can be damaged from power fluctuations. Grounded outlets can help reduce the possibility of personal injury and damage to your computer. They may also allow surge suppressors to safely discharge voltage spikes and prevent damage to your computer. Not all three-pronged outlets are grounded, nor are all two-pronged outlets non-grounded. If in doubt, you may purchase an outlet tester from a hardware or electrical supply store. Always connect your computer to a properly grounded outlet. WARNING! If the outlets in your chosen location are not grounded, either move your computer to a different location or have a qualified electrician ground your outlets. Make sure that the wall outlet you select for your computer does not share the same circuit with any major appliance such as a refrigerator or washing machine. The voltage drop caused by a major appliance powering “on” can lock up, reset, or even damage your computer. If in doubt, you may test the selected outlet before setting up your computer. Do this by plugging a lamp into the selected outlet, turning it on and turning on the appliance(s) that you think may share the same circuit. Next, shut off the breaker or remove the fuse that supplies power to the appliance(s). If the lamp remains lit, the wall outlet is on a separate circuit and may be used. If the lamp shuts off, consider moving your computer to a different location. Alternatively, you may contact a qualified electrician to transfer the wall outlet to a different circuit. Always call a qualified electrician to perform any electrical test or electrical work that you are not comfortable or qualified to do. CAUTION! Do not connect your computer to any wall outlet that shares its circuit with a major appliance. The voltage sags caused by appliances such as a refrigerator powering on can lock up, reset, or even damage your system. CTL strongly recommends the use of a surge suppressor with all computers and computer components. Phenomena such as lightning and switching transformers at the utility station can cause the normal 115-volt current in your wiring to spike, possibly as high as 4,000 volts or more. These extreme voltages can cause damage to your computer. The consistent use of a quality surge suppressor that is plugged into a properly grounded electrical outlet that does not share the same circuit as any major appliance will help ensure that your computer remains unharmed by fluctuations in the power supply. -12 Unpacking Your System Unpacking Your System Examine shipping containers for holes, smashed corners, dents, watermarks, or other damage that may have occurred during shipping. Notify CTL immediately if any of these signs of damage are present. WARNING! Do not install or attempt to connect to a wall outlet any device that appears damaged in any way. Personal injury or damage to your computer may result. Unpack each container and place all system components, cables, and manuals in a place where they may be easily inventoried. Save the packing materials in case you need to ship your system at a later date. Verify each item that you unpack...
