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-TX, 100BASE-TX or
10BASE-T
• Phone lines (Telephone lines, internal phone lines
(onpremise switches), digital public phones, etc.)
Do Not Use with Exposing the Skin to the Computer
for a Long Period of Time
Using the computer with exposing the skin to the heat
source of the computer or AC adaptor for a long period of
time can cause a low-temperature burn.
zDo not place the computer near a television or radio
receiver.
zKeep the computer away from magnets. Data stored
on the hard disk may be lost.
Do Not Use with Any Other Computer
The battery pack is rechargeable and was intended for
the specified computer or charger. If it is used with a com-
puter other than the one for which it was designed, elec-
trolyte leakage, generation of heat, ignition or rupture may
result.
Do Not Charge the Battery Using the Methods Other
Than Indicated in This Manual
If the battery pack is not charged using one of the meth-
ods indicated in this manual, electrolyte leakage, genera-
tion 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 Computer with a Battery Pack Other
Than the One Specified
Use only the specified battery pack (CF-VZSU29A) with
your CF-51. Use of battery packs other than those manu-
factured and supplied by Panasonic may present a safety
hazard (generation of heat, ignition or rupture).
zDo not touch the terminals on the battery pack. The
battery pack may no longer function properly if the
contacts are dirty or damaged.
zDo not expose the battery pack to water, or allow it to
become wet.
zIf 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.
zThis computer prevents overcharging of the battery by
recharging only when the remaining power is less than
approx. 95% of capacity.
zThe 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.
zShould 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
zThe battery pack may become warm during recharging
or normal use. This is completely normal.
zRecharging 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}) (Î 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.)
zIf the temperature is low, the operating time is short-
ened. Only use the computer within the allowable tem-
perature range.
zThis computer has a high temperature mode function
that prevents the degradation of the battery in high
temperature environments. (Î 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.
zThe 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.
zWhen 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.
zAlways 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.
