Safety Precautions
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
}). (

 Operating Instruc-
tions - Reference Manual “Basic Operation” 
“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.)
l
  If the temperature is low, the operating time is 
shortened. Only use the computer within the 
allowable temperature range.
l
  The battery pack is a consumable item. If the 
amount of time the computer can be run by us-
ing a particular battery pack becomes dramati-
cally 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 con-
tacts 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.
