Safety Instructions for Setting Up and Using Your Computer

Plugging In the Power Adapter

Warning Use only the power adapter that came with your Macintosh PowerBook computer. Adapters for other electronic devices (including other Macintosh PowerBook models and other portable computers) may look similar, but they may damage your computer. If your power adapter came equipped with a three-wire grounding plug (a plug that has a third grounding pin), then this plug will fit only a grounded AC outlet. If you are unable to insert the plug into the outlet because the outlet is not grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug!

mAlways leave space around your power adapter. Do not use this equipment in a location where airflow around the power adapter is confined, such as a bookcase.

mAlways disconnect the power adapter and remove the battery before opening the computer to perform procedures such as installing memory or removing the hard disk.

Connecting a Phone Line to the Internal Modem

Warning Do not connect a digital telephone line to the modem, because the wrong type of line could damage the modem.

mAlways disconnect the phone cable before opening the computer to perform procedures such as installing memory or removing the hard disk.

Using Your PowerBook

When using your PowerBook or when charging the battery, it is normal for the bottom of the case to get warm. The bottom of the PowerBook case functions as a cooling surface that transfers heat from inside the computer to the cooler air outside. The bottom of the case is raised slightly to allow airflow that keeps the unit within normal operating temperatures.

Warning Never turn on your computer unless all of its internal and external parts are in place. Operating the computer when it is open or missing parts can be dangerous and damage your computer.
