Troubleshooting
Appendix
Use the Modem With a Regular Telephone Line
Connection to an internal phone line (on-premise switches) of a
company or business office, etc. or to a digital public phone or
use in a country or area not supported by the computer may
result in a fire or electric shocks.
Do Not Connect a Telephone Line, or a Network Cable Other
Than the One Specified, into the LAN Port
If the LAN port is connected to a network such as the ones listed
below, a fire or electric shock may result.
• Networks other than 1000BASE-T, 100BASE-TX or 10BASE-T
• Phone lines (Telephone lines, internal phone lines (on-premise
switches), digital public phones, etc.)
Do Not Use With Exposing the Skin to This Product For a
Long Period of Time
Using this product with exposing the skin to the heat source of
this product or AC adaptor for a long period of time can cause a
low-temperature burn.
Do not place the computer near a television or radio
receiver.
Keep the computer away from magnets. Data stored
on the hard disk may be lost.
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 charged 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 (CF-VZSU43AU) with
your product. Use of battery packs other than those man-
ufactured and supplied by Panasonic may present a
safety hazard (generation of heat, ignition or rupture).
Do not touch the terminals on the battery pack. The
battery pack may no longer function properly if the
contacts are dirty or damaged.
Do not expose the battery pack to water, or allow it to
become wet.
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.
This computer prevents overcharging of the battery by
recharging only when the remaining power is less than
approx. 95% of capacity.
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.
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
The battery pack may become warm during recharging
or normal use. This is completely normal.
Recharging will not commence if internal temperature
of the battery pack is outside of the allowable tempera-
ture range (0 °C to 50 °C {32°F to 122°F}) (
Ref-
erence Manual
“Battery Power”). Once the allowable
range requirement is satisfied, charging begins auto-
matically. 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.)
If the temperature is low, the operating time is short-
ened. Only use the computer within the allowable tem-
perature range.
This computer has a high temperature mode function
that prevents the degradation of the battery in high
temperature environments. (
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 tempera-
ture mode.
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.
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.
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
(
Reference Manual
“LAN”).
