Appendix B Safety, Use, and Care Information B Read this important PowerBook safety and maintenance information. Safety Instructions for Setting Up and Using Your Computer Be aware of the following safety tips and warnings as you work with your PowerBook. Plugging In the Power Adapter Always leave space around your power adapter. Do not use this equipment in a location where airflow around the power adapter or computer is confined. For best results, always connect your AC cord and use a grounded outlet when one is available. Always disconnect the power adapter and remove the battery before opening the computer to perform procedures such as installing memory. Warning: Use only the power adapter that came with your PowerBook computer. Adapters for other electronic devices (including other PowerBook models and other portable computers) might look similar, but they can negatively affect your computer's performance or damage your computer. Connecting a Phone Line to the Internal Modem Always disconnect the phone cord before opening the computer to perform procedures such as installing memory or removing the hard disk. Warning: Do not connect a digital phone line to the modem; the wrong type of line could damage the modem. Contact your telephone service provider if you are unsure whether you have a digital phone line. 73
