Error Codes and Error Types
Syntax error (Error 1):
•An attempt was made to perform an invalid operation. Ex. 2 @{
Calculation error (Error 2):
•The absolute value of an intermediate or final calculation result equals or exceeds 10100.
•An attempt was made to divide by 0 (or an intermediate calculation resulted in zero).
•The calculation ranges were exceeded while performing calculations.
Depth error (Error 3):
•The available number of buffers was exceeded. (There are 10 buffers* for numeric values and 24 buffers for calculation instructions).
*5 buffers in STAT mode and complex number mode.
•Data items exceeded 100 in the statistics mode.
Equation too long (Error 4):
•The equation exceeded its maximum input buffer (142 characters). An equation must be shorter than 142 characters.
Equation recall error (Error 5):
•The stored equation contains a function not available in the mode used to recall the equation. For example, if a numerical value with numbers other than 0 and 1 is stored as a decimal, etc., it cannot be recalled when the calculator is set to binary.
Memory over error (Error 6):
•Equation exceeded the formula memory buffer (256 characters in total in F1 - F4).
Calculation Ranges
•Within the ranges specified, this calculator is accurate to ±1 of the least significant 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, x¿ , ex, ln, 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
If the absolute value of an entry or a final or intermediate result of a calculation is less than
BATTERY REPLACEMENT
Notes on Battery Replacement
Improper handling of batteries can cause electrolyte leakage or explosion. Be sure to observe the following handling rules:
•Replace both batteries at the same time.
•Do not mix new and old batteries.
•Make sure the new batteries are the correct type.
•When installing, orient each battery properly as indicated in the calculator.
•Batteries are
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 Batteries
If the display has poor contrast or nothing appears on the display even when ªis pressed in dim lighting, it is time to replace the batteries.
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 fluid 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 leaking batteries, remove them and store in a safe place.
•Do not leave exhausted batteries inside the product.
•Do not fit partially used batteries, and be sure not to mix batteries of different types.
•Keep batteries out of the reach of children.
•Exhausted batteries left in the calculator may leak and damage the calculator.
•Explosion risk may be caused by incorrect handling.
•Do not throw batteries into a fire as they may explode.
Replacement Procedure
1.Turn the power off by pressing @F.
2.Remove the two screws. (Fig. 1)
3.Slide the battery cover slightly and lift it to remove.
4.Remove the used batteries by prying them out with a
5.Install two new batteries. Make sure the “+” side is facing up.
6.Replace the cover and screws.
7.Press the RESET switch (on the back).
•Make sure that the display appears as shown below. If the display does not appear as shown, remove the batteries, rein- stall them and check the display once again.
