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.
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:
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.
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.
