							This apparatus must be earthed for your safety.
To ensure safe operation the three-pin plug must be inserted only into a \
standard three-pin power point
which is effectively earthed through the normal household wiring.
Extension cords used with the equipment must be three-core and be correc\
tly wired to provide connec-
tion to earth. Wrongly wired extension cords are a major cause of fatalities.
The fact that the equipment operates satisfactorily does not imply that \
the  power point is earthed and
that the installation is completely safe.
For your safety, if you have any doubt about the effective earthing of the power point, consult a quali-
fied electrician.
FOR YOUR SAFETY PLEASE READ THE FOLLOWING TEXT CAREFULLY
This appliance is supplied with a moulded three pin mains plug for your \
safety and convenience.
A 3 amp fuse is fitted in this plug.
Should the fuse need to be replaced please ensure that the replacement f\
use has a rating of 3 amps and
that it is approved by ASTA or BSI to BS 1362.
Check for the ASTA mark 
 or the BSI mark  on the body of the fuse.
If the plug contains a removable fuse cover you must ensure that it is r\
efitted when the fuse is replaced.
If you lose the fuse cover the plug must not be used until a replacement\
 cover is obtained.
A replacement fuse cover can be purchased from your local Panasonic Deal\
er.
IF THE FITTED MOULDED PLUG IS UNSUITABLE FOR THE SOCKET OUTLET IN YOUR
HOME THEN THE FUSE SHOULD BE REMOVED AND THE PLUG CUT OFF AND DISPOSED
OF SAFELY.
THERE IS A DANGER OF SEVERE ELECTRICAL SHOCK IF THE CUT OFF PLUG IS INSE\
RTED
INTO ANY 13 AMP SOCKET.
If a new plug is to be fitted please observe the wiring code as shown be\
low.
If in any doubt please consult a qualified electrician.
Warning: THIS APPLIANCE MUST BE EARTHED.
Important
The wires in this mains lead are coloured in accordance with the followi\
ng code:
Green-and-yellow: Earth
Blue: Neutral
Brown: Live
As the colours of the wires in the mains lead of this apparatus may not \
correspond with the coloured
markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured GREEN-and-YELLOW must be connected to the ter\
minal in the plug
which is marked by the letter E or by the safety earth symbol 
 coloured GREEN or GREEN-and-
YELLOW.
The wire which is coloured Blue must be connected to the terminal which \
is marked with the letter N or
coloured BLACK.
The wire which is coloured Brown must be connected to the terminal which\
 is marked with the letter L
or coloured RED.
The mains plug on this equipment must be used to disconnect the mains po\
wer.
Please ensure that a socket outlet is available near the equipment and s\
hall be easily accessible.
How to replace the fuse
Open the fuse compartment with a screw-
driver and replace the fuse.
WarningsThis equipment is not designed for connection to an IT power system.
(An IT system is a system having no direct connections between live par\
ts and Earth; the exposed-conducive-
parts of the electrical installation are earthed.
An IT system is not permitted where the computer is directly connected t\
o public supply systems in the U.K.)
Disconnect the mains plug from the supply socket when  the computer is n\
ot in use.
This equipment is produced to BS800/1983.

Appendix
Do Not Use with Any Other Product
The battery pack is rechargeable and was intended for
the specified product. If it is used with a product other
than the one for which it was designed, electrolyte leak-
age, generation of heat, ignition or rupture may result.
Do Not Charge the Battery Using Methods Other Than
Those Specified
If the battery is not charge d using one of the specified
methods, electrolyte leakage,  generation of heat, ignition
or rupture may result.
Do Not Throw the Battery Pack into a Fire or Expose It
to Excessive Heat
Generation of heat, ignition or rupture may result.
Avoid Extreme Heat (Near the Fire, in Direct Sunlight,
for Example)
Electrolyte leakage, generation  of heat, ignition or rupture
may result.
Do Not Insert Sharp Objects into the Battery Pack,
Expose It to Bumps or Shocks, Disassemble, or Mod-
ify It
Electrolyte leakage, generation  of heat, ignition or rupture
may result.
Do Not Short the Positive (+) and Negative (-) Con-
tacts
Generation of heat, ignition or rupture may result. Do not
place the battery pack together with articles such as neck-
laces or hairpins when carrying or storing.
Do Not Use This Product with a Battery Pack Other
Than the One Specified
Use only the specified battery pack with your product.
Use of battery packs othe

r than those manufactured and
supplied by Panasonic may present a safety hazard 
(generation of heat, ignition or rupture). z
Do not touch the termin

als on the battery pack. The 
battery pack may no longer function properly if the 
contacts are dirty or damaged.
z Do not expose the battery pack to water, or allow it to 
become wet.
z If the battery pack  will not be used for a long period of 
time (a month or more), charge or discharge (use) the 
battery pack until the remaining battery level becomes 
30% to 40% and store it in a cool, dry place.
z This computer prevents overcharging of the battery by 
recharging only when the remaining power is less than 
approx. 95% (when Economy Mode (ECO) is enabled: 
75%) of capacity.
z The battery pack is not charged when the computer is 
first purchased.  Be sure to charge it before using it for 
the first time.  When the AC adaptor is connected to 
the computer, charging begins automatically.
z Should the battery leak and the fluid get into your 
eyes, do not rub your eyes.  Immediately flush your 
eyes with clear water and see a doctor for medical 
treatment as soon as possible.
NOTE
z The battery pack may become warm during 
recharging or normal use.   This is completely nor-
mal.
z Recharging will not commenc e if internal tempera-
ture of the battery pack is outside of the allowable 
temperature range (0 °C to 55 °C {32 °F to 131 
°F}). (
