•The absolute value of an intermediate or fi nal calculation result equals or exceeds 10100.
•An attempt was made to divide by zero (or an intermediate calculation resulted in zero).
•The calculation ranges were exceeded while performing calculations.ERROR 03: Nesting error•The available number of buffers was exceeded. (There are 10 buffers for numeric values and 64 buffers for calculation instructions).
ERROR 04: Data over• Data items exceeded 100 in STAT mode.Alert Messages | 18 |
In this example, delete the exponent before attempting to delete the parentheses.
Cannot call!•The function or operation stored in defi nable memory (D1 to D4) cannot be called.
Ex. An attempt was made to recall a statistical variable from within NORMAL mode.
Buffer full!•The equation (including any calculation ending instructions) exceeded its maximum input buffer (159 characters in the WriteView editor or 161 characters in the Line editor). An equation may not exceed its maximum input buffer.

Calculation Ranges | 19 | |
• | Within the ranges speciÞed, 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, etc., where continuous calculations | |
| are performed internally.) | |
| Additionally, a calculation error will accumulate and | |
| become larger in the vicinity of inßection 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 rCalculation 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:
±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 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.

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
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
Cautions
•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.
•An exhausted battery left in the calculator may leak and damage the calculator.
•Explosion risk may be caused by incorrect handling.•Do not throw batteries into a fi re as they may explode.Replacement Procedure
