AC Power Safety Warning
WARNING: Install the computer near an AC
outlet. The AC power cord is your computer's
main AC disconnecting device and must be easily
accessible at all times. For your safety, the
power cord provided with your computer has a
grounded plug. Always use the power cord with
a properly grounded wall outlet, to avoid the
risk of electrical shock.
WARNING: Your computer is provided with a
voltage select switch for use in a 115 or 230 V
power system. The voltage select switch has
been pre-set to the correct voltage setting for use
in the particular country/region where it was
initially sold. Changing the voltage select switch
to the incorrect position can damage your
computer and void any implied warranty.
WARNING: To reduce the possibility of an electric
shock from the telephone network, plug your
computer into the AC outlet before connecting it
to the telephone line. Also, disconnect the
telephone line before unplugging your computer
from the AC power outlet.
WARNING: Always disconnect the modem cord
from the telephone system before installing or
removing your computer cover.
WARNING: Do not operate the computer with the
cover removed.
WARNING: For your safety, always unplug the
computer from its power source and from any
telecommunications systems (such as telephone
lines), networks, or modems before performing
any service procedures. Failure to do so may
result in personal injury or equipment damage.
Hazardous voltage levels are inside the power
supply and modem of this product.
Lithium Battery Caution
WARNING: The computer uses a lithium battery,
type CR2032. There is danger of an explosion if
the battery is incorrectly replaced. Replace only
with the same, or equivalent, type recommended
by the manufacturer. Dispose of used batteries
according to the manufacturer's instructions.
