Appendix Safety, Maintenance, B and Ergonomics B This appendix provides important information about safety procedures, routine maintenance, and ergonomic considerations for using your computer and display. Important Safety Information The only way to disconnect power completely from your computer is to unplug the power cord from the main power supply. To disconnect your display completely, you must also unplug its power cable from the computer or power outlet. Make sure that at least one end of the device's power cord is within easy reach so that you can unplug the computer or display when necessary. For your own safety and that of your equipment, always take the following precautions. Disconnect the power plug (by pulling the plug, not the cord), from your computer or display and disconnect the phone cord if any of the following conditions exists:  The power cord or plug becomes frayed or otherwise damaged  You spill something into the case  Your computer or display is exposed to rain or any other excess moisture  Your computer or display has been dropped or the case has been otherwise damaged  You suspect that your computer or display needs service or repair  You want to clean the computer or display case or screen  You notice a coolant leak in or from your computer (for Power Mac G5 models equipped with a liquid cooling system) 83
