[. . . ] · A complex number is represented in the a + bi format. The "a" is the real part while the "bi" is the imaginary part. When inputting the real part, after inputting the number press a. When inputting the imaginary part, after inputting the number press b. · Immediately after completing calculation, you can recall the value of the real part with a, and the value of the imaginary part with b. · If the complex numbers are represented as polar coordinates, press @} after they are input with a and b. * (n: integer) 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 (LR44). · When installing, orient each battery properly as indicated in the calculator. · Batteries are factory-installed before shipment, and may be exhausted before they reach the service life stated in the specifications. SCIENTIFIC CALCULATIONS · Calculate in the normal mode. · The results of inverse trigonometric functions are displayed within the following range: = sin­1 x, = tan­1 x DEG RAD GRAD = cos­1 x 0 180 0 0 200 Replacement Procedure 1. Loosen both screws and remove the battery cover. 2 CPLX : Indicates that @ has been pressed. STAT M E : Indicates that @ Æ has been pressed. : Indicates that a numerical value is stored in the independent memory. : Appears when an error is detected. ­---- 2 2 ­100 100 ­90 90 Statistical Calculation Formulas Random Numbers A pseudo-random number with three significant digits can be generated by pressing @ `. Random number generation is not possible when binary/octal/hexadecimal system mode is set. x = x n sx = x2 ­ nx2 n­1 x = x2 ­ n nx2 x = x1 + x2 + ··· + xn x2 = x12 + x22 + ··· + xn2 (n: Number of samples) In the statistical calculation formulas, an error will occur when: · the absolute value of the intermediate result or calculation result is equal to or greater than 1 × 10100. · an attempt is made to take the square root of a negative number. BEFORE USING THE CALCULATOR Key Notation Used in this Manual In this manual, key operations are described as follows: A Exp To specify A (HEX) : A To specify :@V To specify Exp :E Angular Unit Conversions (4) Each time @ g are pressed, the angular unit changes in sequence. 3. Remove the used batteries then replace with two fresh batteries with the positive sides (+) facing up. · Make sure that the display appears as shown below. If the display does not appear as shown, reinstall the batteries and check the display once again. Memory Calculations (5) Functions that are printed in orange above the key require @ to be pressed first before the key. [. . . ] In the case of an error, the display will show "E". An error can be cleared by pressing ª. Automatic Power Off Function This calculator will turn itself off to save battery power if no key is pressed for approximately 8 minutes.
