the computer according to the following instructions to sustain the quality finish indefinitely. Should
the finish
be damaged, consult your local HP Sales and Support Office (Appendix G) for available
touch-up paints.

soap. Wipe the soiled areas of the computer, ensuring that no cleaning solution gets inside the
computer. For cleaning more heavily soiled areas, a solution of

at the rear. Ensure that the
grill is free of obstructions at all times. Vacuum or brush grill as
