Plug, or the AC Adaptor
Do not damage or modify the cord, place it near hot tools,
bend, twist, or pull it forcefully, place heavy objects on it,
or bundle it tightly.
Continuing to use a damaged cord may result in fire, short
circuit, or electric shock.
Do Not Pull or Insert the AC Plug If Your Hands Are Wet
Electric shock may result.
Clean Dust and Other Debris of the AC Plug 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.
• 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.
Insert the AC Plug Completely
If the plug is not inserted completely, fire due to overheat-
ing or electric shock may result.
• Do not use a damaged plug or loose AC outlet.
Do Not Place Containers of Liquid or Metal Objects on Top
of This Product
If water or other liquid spills, or if paper clips, coins, or for-
eign matter get inside this product, fire or electric shock
may result.
• If foreign matter has found its way inside, immediately
turn the power off and unplug the AC plug and remove
the battery pack. Then contact your technical support
office.
Do Not Disassemble This Product
There are high-voltage areas inside which may give you
an electric shock if you should touch them. Do not touch
the pins and circuit boards inside, and do not allow foreign
matter to enter inside.
Also, remodeling or disassembly may cause a fire.
Keep SD Memory Cards Away from Infants and Small Chil-
dren
Accidental swallowing will result in bodily injury.

Moisture, Steam, Dust, Oily Vapors, etc.
Otherwise, possibly resulting in fire or electric shock.
Do Not Leave This Product in High Temperature Environment
Such as in a Sun-Heated Car, for a Long Period of Time
Leaving this product where it will be exposed to extremely
high temperatures such as in a sun-heated car or in direct
sunlight may deform the cabinet and/or cause trouble in the
internal parts. Continued use in such a resulting condition
may lead to short-circuiting or insulation defects, etc. which
may in turn lead to a fire or electric shocks.
Do Not Block the Ventilation Hole
Otherwise, heat will build up inside, possibly resulting in a fire.
Hold the Plug When Unplugging the AC Plug
Pulling on the cord may damage the cord, resulting in a
fire or electric shock.
Do Not Move This Product While the AC Plug Is Connected
The AC cord may be damaged, resulting in fire or electric shock.

Use Only the Specified AC Adaptor With This Product
Using an AC adaptor other than the one supplied
(attached to your product or supplied by Panasonic) may
result in a fire.
Do Not Subject the AC Adaptor to Any Strong Impact
Using the AC adaptor after a strong impact such as being
dropped may result in electric shock, short circuit, or fire.
Take a Break of 10-15 Minutes Every Hour
Using this product for long periods of time may have detri-
mental health effects on the eyes or hands.
Do Not Look into the CD/DVD Drive
Looking directly at the internal laser light source may
result in damage to eyesight.
Do Not Use Discs That Are Cracked or Deformed
Because the discs rotate at high speeds, damaged discs
may break apart causing injury.
• Discs that are not round and discs that have been
repaired using adhesives are similarly dangerous, and
so should not be used.
Do Not Turn the Volume Up to Loud When Using Head-
phones
Listening at high volumes that overstimulate the ear for
long periods of time may result in loss of hearing.
