Apple PowerBook (Duo, 2300 Series) - Manual (Page 139)

m Use only the power adapter supplied with your computer, or an identical
model. Adapters designed for other electronic devices may not work with
your equipment and may damage it.
Important
m Use the computer (alone or connected to a minidock or floppy disk
adapter) only in environments where the temperature range is between
41°F/5°C and 95°F/35°C. Use the computer in a Duo Dock Plus (or other
Duo Dock model) only in environments where the temperature range is
between 41°F/5°C and 86°F/30°C.
m Do not expose the computer to very low (less than –13°F/–25°C) or very
high (more than 140°F/60°C) temperatures.
m If the computer has been in a cold place for several hours, let it warm up to
room temperature before you use it.
m Clean the computer’s outside surfaces with a damp (not wet) cloth. Clean
the screen with soft, lint-free paper or cloth and a mild glass cleaner. Do
not spray the glass cleaner directly onto the screen. Rough paper towels
may scratch the screen.
