Operational Notes

Do not carry the calculator around in your back pocket, as it may break when you sit down. The display is made of glass and is particularly fragile. Keep the calculator away from extreme heat such as on a car dashboard or near a heater, and avoid exposing it to excessively humid or dusty environments. Since this product is not waterproof, do not use it or store it where fluids, for example water, can splash onto it. Raindrops, water spray, juice, coffee, steam, perspiration, etc., will also cause malfunction. Clean with a soft, dry cloth. Do not use solvents or wet cloth. Do not drop it or apply excessive force. Never dispose of battery in a fire. Keep battery out of the reach of children. This product, including accessories, may change due to upgrading without prior notice. SHARP will not be liable nor responsible for any incidental or consequential economic or property damage caused by misuse and/or malfunctions of this product and its peripherals, unless such liability is acknowledged by law. Press the RESET switch (on the back), with the tip of a ball-point pen or similar object, only in the following cases. Do not use an object with a breakable or sharp tip. Note that pressing the RESET switch erases all data stored in memory. When using for the first time After replacing the battery To clear all memory contents When an abnormal condition occurs and all keys are inoperative. If service should be required on this calculator, use only a SHARP servicing dealer, SHARP approved service facility, or SHARP repair service where available.

Scientific (Exponential) Notation
People who need to deal with very large and very small numbers often use a special format called exponential or scientific notation. A number expressed in scientific notation has two parts. The first part consists of a regular decimal number between 1 and 10. The second part represents how large or small the number is in powers of 10. While a calculation result is displayed in the floating point system, press @ to display the result in the scientific notation system. Pressing @ once again will bring back the floating point system. To enter a number in scientific notation, press E.

BATTERY REPLACEMENT Notes on Battery Replacement
Improper handling of battery 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 correctly as indicated in the calculator. The factory-installed battery may be exhausted before they reach the service life stated in the specifications.

Errors

An error will occur if an operation exceeds the calculation ranges, or if a mathematically illegal operation is attempted. If an error occurs, pressing < (or >) automatically moves the cursor back to the place in the equation where the error occurred. Edit the equation or press N to clear the equation.
If = is pressed instead of a number entry, the least common denominator will automatically be displayed.

An attempt was made to divide by 0 (or an intermediate calculation resulting in 0). The calculation ranges were exceeded while performing calculations. The solution of a quadratic equation is a complex number. 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 and EQN mode. Equation too long (Error 4): The equation exceeded the maximum input buffer (159 characters). An equation must be shorter than 159 characters.
When to Replace the Battery
If the display has poor contrast or nothing appears on the display even when N is pressed, it is time to replace the battery.
Up to 10 key strokes, including and /, can be used to enter a fraction.

Caution

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 into 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 battery, remove it and store in a safe place. Keep battery out of the reach of children. Exhausted battery left in the calculator may leak and damage the calculator. Explosion risk may be caused by incorrect handling. Do not throw battery into a fire as they may explode.
Calculating with Fractions
Fractions can be incorporated into an arithmetic calculation. The SIMP symbol will appear with a calculation result if the answer can be further simplified. Refer to the following section of this manual for details.

Calculation Ranges

Within the ranges specified below, 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, n!, ln, mod, etc. where continuous calculations are performed internally.) Furthermore, a calculation error will accumulate and become larger in the vicinity of inflection points and singular points of functions. Calculation range: 1099 ~ 9.9999999991099 and 0. If the absolute value of an entry or a final or intermediate result of a calculation is less than 1099, the value is considered to be 0 in calculations and in the display.
