Question  
Decimal calculation results are internally obtained in scientific  
notation, with up to 14 digits in the mantissa. However, since  
calculation results are displayed in the form designated by the  
display notation and the number of decimal places indicated,  
the internal calculation result may differ from that shown in the  
display. By using the modify function (@ n), the internal  
value is converted to match that of the display, so that the  
displayed value can be used without change in subsequent  
operations.

An error will occur when:  
Statistics of and . In addition, the estimate of y for a given  
x and the estimate of x for a given y. (Since the calculator  
converts each formula into a linear regression formula before  
actual calculation takes place, it obtains all statistics, except  
coefficients a and b, from converted data rather than entered  
data.)  
Errors  
• The absolute value of the intermediate result or calculation  
An error will occur if an operation exceeds the calculation ranges,  
or if a mathematically illegal operation is attempted. When an error  
occurs, pressing l or r automatically moves the cursor  
back to the place in the equation where the error occurred. Edit  
the equation or press j to clear the equation.  
result is equal to or greater than 1 × 10100  
.
• The denominator is zero.  
• An attempt is made to take the square root of a negative  
number.  
• No solution exists in the quadratic regression calculation.  
Error codes and error types  
• 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.  
ERROR 01: Syntax error  
• An attempt was made to perform an invalid operation.  
Ex. 2 + & 5 =  
ERROR 02: Calculation error  
• The absolute value of an intermediate or final calculation  
• Explosion risk may be caused by incorrect handling.  
• Do not throw batteries into a fire as they may explode.  
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.  
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.EL-W531/W531G/W535: Remove the used battery by  
prying it out with a ball-point pen or other similar pointed  
device. (Fig. 2)  
ERROR 03: Nesting error  
• The available number of buffers was exceeded. (There are  
10 buffers for numeric values and 64 buffers for calculation  
instructions).  
EL-W531H/W531HA: Remove the used battery.  
5.EL-W531/W531G/W535: Install one new battery. Make sure  
the “+” side is facing up.  
ERROR 04: Data over  
• Data items exceeded 100 in STAT mode.  
EL-W531H/W531HA: Install one new battery. First insert the  
” side toward the spring. (Fig. 3)

Alert Messages  
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.  
Cannot delete!  
• The selected item cannot be deleted by pressing N or  
@ y in the WriteView editor.  
Ex. * 5 r A l N  
In this example, delete the exponent before attempting to  
delete the parentheses.  
Cannot call!  
• The function or operation stored in definable 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  
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

Additionally, a calculation error will accumulate and  
become larger in the vicinity of inflection points and  
singular points of functions.
