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 correctly wired to provide connection 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 qualified 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 fuse 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 refitted 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 Dealer.
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 INSERTED
INTO ANY 13 AMP SOCKET.
If a new plug is to be fitted please observe the wiring code as shown below.
If in any doubt please consult a qualified electrician.
Warning: THIS APPLIANCE MUST BE EARTHED.

Precautions (Battery Pack)
Do Not Use With Any Other Product
The battery pack is rechargeable and was intended for the
product. If it is used with a product other than the one
for which it was designed, electrolyte leakage, generation of
heat, ignition or rupture may result.
Do Not Charge the Battery Using Methods Other Than
If the battery is not charged using one of the
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 Modify It
Electrolyte leakage, generation of heat, ignition or rupture may result.
Ÿ If this product is subjected to a strong impact, stop using it immediately.
Do Not Short the Positive (+) and Negative (-) Contacts
Generation of heat, ignition or rupture may result.
Ÿ Do not place the battery pack together with articles such
as necklaces or hairpins when carrying or storing.
Do Not Use This Product with a Battery Pack Other Than
Use only the
battery pack (CF-VZSU46AU) with your
product. Use of battery packs other than those manufactured
and supplied by Panasonic may present a safety hazard (generation of heat, ignition or rupture).
When the battery pack has become degraded, replace it
with a new one
Continued use of a damaged battery pack may result in heat
generation, ignition or battery rupture.
l Do not touch the terminals on the battery pack. The battery pack may
no longer function properly if the contacts are dirty or damaged.
l Do not expose the battery pack to water, or allow it to become wet.
l 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.
l This computer prevents overcharging of the battery by recharging only
when the remaining power is less than approx. 95% of capacity.

l The battery pack is not charged when the computer is
Be sure to charge it before using it for the
time. When the AC
adaptor is connected to the computer, charging begins automatically.
get into your eyes, do not rub
l Should the battery leak and the
your eyes. Immediately
your eyes with clear water and see a
doctor for medical treatment as soon as possible.
CAUTION:
Risk of Explosion if Battery is replaced by an Incorrect Type.
Dispose of Used Batteries According to the Instructions.
ATTENTION:
Il y a risque d’explosion si la batterie est remplacée par une batterie
de type incorrect.
Mettre au rebut les batteries usagées conformément aux instructions.
NOTE
l The battery pack may become warm during recharging or
normal use. This is completely normal.
l Recharging will not commence if internal temperature of the
battery pack is outside of the allowable temperature range (0
°C to 50 °C {32°F to 122 °F}).
(è
Reference Manual “Battery Power”) Once the allowable range requirement is
charging begins automatically. Note that the recharging time varies based on the
usage conditions. (Recharging takes longer than usual when
the temperature is
10 °C {50 °F} or below.)
l If the temperature is low, the operating time is shortened.
Only use the computer within the allowable temperature
range.
l This computer has a high temperature mode function that
prevents the degradation of the battery in high temperature
environments. (è
Reference Manual “Battery Power”) A
level corresponding to a 100% charge for high temperature
mode is approximately equivalent to an 80% charge level for
normal temperature mode.
l The battery pack is a consumable item. If the amount of
time the computer can be run by using a particular battery
pack becomes dramatically shorter and repeated recharging
does not restore its performance, the battery pack should be
replaced with a new one.
l When transporting a spare battery inside a package, briefcase, etc., it is recommended that it be placed in a plastic
bag so that its contacts are protected.
l Always power off the computer when it is not in use. Leaving
the computer on when the AC adaptor is not connected will
exhaust the remaining battery capacity.
A lithium ion battery that is recyclable powers the product you have purchased.
Please call 1-800-8-BATTERY for information on how to recycle this battery.
L’appareil que vous vous êtes procuré est alimenté par une batterie au lithium-ion.
