Calculation Ranges
• Within the ranges specifi ed, this calculator is accurate to
1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same
x x r, n!, e
y
x
for , , ln, Matrix/List calculations, etc., where
continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of infl ection points and
singular points of functions.
• Calculation ranges
10 99 to 9.999999999
If the absolute value of an entry or a fi nal or intermediate
result of a calculation is less than 10
considered to be 0 in calculations and in the display.
Display of results using r
Calculation results may be displayed using r when all of the
following conditions are met:
• When intermediate and fi nal calculation results are displayed
in the following form:
a P b c P d
e
f
• When each coeffi cient falls into the following ranges:
1 a 100; 1 b 1,000; 0
1 d 1,000; 1 e 100; 1
• When the number of terms in the intermediate and fi nal
calculation results is one or two.
Note: The result of two fractional terms that include r will be
reduced to a common denominator.

BATTERY REPLACEMENT

Notes on Battery Replacement
Improper handling of batteries 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 properly as indicated in the
calculator.
• The battery is factory-installed before shipment, and may
be exhausted before it reaches the service life stated in the
specifi cations.
Notes on 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 nothing appears on the display
when j is pressed in dim lighting, even after adjusting the
display contrast, it is time to replace the battery.
Cautions
• An exhausted battery left in the calculator may leak and
damage the calculator.
• Fluid from a leaking battery accidentally entering an eye could
result in serious injury. Should this occur, wash with clean
water and immediately consult a doctor.
• Should fl uid from a leaking battery come in contact with your
skin or clothes, immediately wash with clean water.
• If the product is not to be used for some time, to avoid damage
to the unit from a leaking battery, remove it and store in a safe
place.
• Do not leave an exhausted battery inside the product.
• Keep batteries out of the reach of children.
• Explosion risk may be caused by incorrect handling.
• Do not throw batteries into a fi re as they may explode.

Replacement Procedure
1. Turn the power off by pressing @ o.
2. Remove the two screws. (Fig. 1)
3. Slide the battery cover slightly and lift it
to remove.
4. Remove the used battery by prying it
out with a ball-point pen or other similar
pointed device. (Fig. 2)
5. Install one new battery. Make sure the
" " side is facing up.
6. Replace the cover and screws.
7. Press the RESET switch (on the back)
with the tip of a ball-point pen or similar object.
8. Adjust the display contrast. See "Adjusting the Display
Contrast".
• Make sure that the display appears as shown below. If the
display does not appear as shown, remove the battery,
reinstall it, and check the display once again.
Automatic Power Off Function
This calculator will turn itself off to save battery power if no
key is pressed for approximately 10 minutes.
