may increase the risk of fire or explosion.
Replace the battery only with a compatible
battery purchased from Dell that is
designed to work with your Dell computer.
Do not use a battery from other computers
with your computer.
Audio Safety
WARNING: Excessive sound pressure
from earphones or headphones can cause
hearing damage or loss. Adjustment of the
volume control as well as the equalizer to
settings other than the center position may
increase the earphones or headphones
output voltage, and therefore the sound
pressure level.
The use of factors influencing the earphones or
headphones output other than those specified
by the manufacturer (e.g. operating system,
equalizer software, firmware, driver, etc.) may
68
increase the earphones or headphones output
voltage and therefore the sound pressure level.
The use of earphones or headphones other than
those specified by the manufacturer may lead to
heightened sound pressure level.

keyboard use may result in injury.
WARNING: Viewing a display or external
monitor screen for extended periods of
