Notes on battery replacement
Improper handling of battery can cause electrolyte leakage or 
explosion. Be sure to observe the following handling rules:
  Make sure the new battery is the correct type.
  When installing, orient the battery correctly, as indicated in the 
calculator.
  The factory-installed battery may be exhausted before it 
reaches the service life stated in the speci cations.
Note on the erasure of memory contents
When the battery is replaced, the memory contents are 
erased. Erasure can also occur if the calculator is defective 
or when it is repaired. Make a note of all important memory 
contents in case accidental erasure occurs.
When to replace the battery
If the display has poor contrast, or if nothing appears on the 
screen, even when 
s is pressed, it is time to replace the bat-

result in serious injury. Should this occur, wash with clean 
water and immediately consult a doctor.
 Should  uid from a leaking battery come into contact with your 
skin or clothes, wash them immediately with clean water.
  If the product is not to be used for some time, to avoid dam-
age to the unit from leaking battery, remove it and store in a 
safe place.
  Keep battery out of the reach of children.
  Exhausted battery that is left in the calculator may leak and 
damage the unit.
  Explosion risk may be caused by incorrect handling.
  Do not throw battery into a  re, as it may explode.
