Preparations
Precautions (Wireless LAN) <
Only for models with wireless LAN>
Clean the DC plug of dust and other
debris regularly
If dust or other debris accumulates on the
plug, humidity, etc. may cause a defect in
the insulation, which may result in a fire.
z
Pull the plug, and wipe it with a dry
cloth.
Pull the plug if the computer is not
being used for a long period of time.
Do not pull or insert the DC plug if
your hands are wet
May result in electrical shock.
Insert the AC plug completely
If the plug is not inserted completely, fire
due to overheating or electrical shock
may result.
z
Do not use a damaged plug or loose
electrical socket.
Do not place metal objects or contain-
ers of liquid on top of the computer
z
If water or other liquid spills, or if paper
clips, coins, or other metal objects get
inside the computer, fire or electrical
shock may result.
Do not place the computer on unstable
surfaces
If balance is lost, the computer may fall
over or drop, resulting in an injury.
Do not move the computer while the
DC plug is connected
The AC cord may be damaged, resulting
in fire or electrical shock.
z
If the AC cord is damaged, remove the
DC plug immediately.
Hold the plug when unplugging the AC
cord
Pulling on the cord may damage the cord,
resulting in a fire or electrical shock.
Do not turn the volume up to loud
when using headphones
Listening at high volumes that overstimu-
late the ear for long periods of time may
result in loss of hearing.
Take a break of 10-15 minutes every
hour
Using the computer for long periods of
time may have detrimental health effects
on the eyes or hands.
Do not look into the DVD-ROM & CD-R/
RW drive
Looking directly at the internal laser light
source may result in damage to eyesight.
Do not use disks that are cracked or
deformed
Because the disks rotate at high speeds,
damaged disks may break apart causing
injury.
z
Disks that are not round and disks that
have been repaired using adhesives
are similarly dangerous, and so should
not be used.
Do not cover the computer with a thick
cloth, such as a blanket
