Calculation Ranges | 30 |
•Within the ranges specified, 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 for yx, xr, n!, ex, ln, Matrix/List calculations, etc., where
continuous calculations are performed internally.) Additionally, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions.
•Calculation ranges
±10−99 to ±9.999999999 ⋅ 1099 and 0.
If the absolute value of an entry or a fi nal or intermediate result of a calculation is less than 10−99, the value is considered to be 0 in calculations and in the display.
Display of results using r
Calculation results may be displayed using rwhen all of the following conditions are met:
•When intermediate and final calculation results are displayed in the following form:
±aPb ± cPd
⎯ ⎯
e f
• When each coeffi cient falls into the following ranges: 1 ≤ a < 100; 1 < b < 1,000; 0 ≤ c < 100;
1 ≤ d < 1,000; 1 ≤ e < 100; 1 ≤ f < 100
•When the number of terms in the intermediate and final calculation results is one or two.
Note: The result of two fractional terms that include rwill 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
Notes on erasure of memory contents
When the battery is replaced, the memory contents are erased.
Replacement Procedure
1.Turn the power off by pressing @o.
2.Remove the two screws. (Fig. 1) | Fig. 1 |
3.Slide the battery cover slightly and lift it |
|
to remove. |
|
4.Remove the used battery by prying it |
|
out with a |
|
pointed device. (Fig. 2) | 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
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.

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. |
