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.
Use the Modem with a Regular Telephone Line
Connection to an internal phone line (on-premise switches) 
of a company or business offi ce, etc. or to a digital public 
phone or use in a country or area not supported by the com-
puter may result in a fi re or electric shocks.
Do Not Connect a Telephone Line, or a Network Cable 
Other Than the One Specifi ed, into the LAN Port
If the LAN port is connected to a network such as the ones 
listed below, a fi re or electric shock may result.
  Networks other than 100BASE-TX or  10BASE-T
  Phone lines (IP Phone, Telephone lines, internal phone 
lines (on-premise switches), digital public phones, etc.)
Precautions (Battery Pack)
Do Not Use with Any Other Product
The battery pack is rechargeable and was intended for the 
specifi ed product. If it is used with a product other than the 
one for which it was designed, electrolyte leakage, genera-
tion of heat, ignition or rupture may result.
Do Not Charge the Battery Using the Methods Other 
Than Those Specifi ed
If the battery is not charged using one of the specifi ed 
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, Ex-
pose It to Bumps or Shocks, Disassemble, or Modify It
Electrolyte leakage, generation of heat, ignition or rupture 
may result.
Do Not Short the Positive (+) and Negative (-) Contacts
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 Specifi ed
Use only the specifi ed battery pack (CF-VZSU48U) 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).
  Do not touch the terminals on the battery pack.  The bat-
tery 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.
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 re-
ceiver.
 Keep the computer away from magnets. Data stored on 
the hard disk may be lost.
  The battery pack is not charged when the computer is 
fi rst purchased.  Be sure to charge it before using it for 
the fi rst time.  When the AC adaptor is connected to the 
computer, charging begins automatically.
  Should the battery leak and the fl uid get into your eyes, 
do not rub your eyes.  Immediately fl ush your eyes with 
clear water and see a doctor for medical treatment as 
soon as possible.
 NOTE 
  The battery pack may become warm during recharg-
ing or normal use.  This is completely normal.
  Recharging will not commence if internal temperature 
of the battery pack is outside of the allowable temper-
ature range (0 °C to 50 °C {32°F to 122 °F}). 
(
   Reference Manual “Battery Power”) Once the 
allowable range requirement is satisfi ed, 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.)
  If the temperature is low, the operating time is short-
ened.  Only use the computer within the allowable 
temperature 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 re-
peated 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.
