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 y x, 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 final 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 r when all of the following conditions are met: • When intermediate and final calculation results are displayed in the following form: ±a⎯ P eb ± c⎯ P fd • When each coefficient 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 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 specifications. 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 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 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 fire as they may explode. 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 ball-point pen or other similar 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 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.
