ייַנמאָנטירונג פון באַטאַרייע

The Sharp EL-531TGBBW calculator operates on Twin Power (solar and battery). One AAA battery is included. To install or replace the battery:

1. זייט זיכער אז דער קאַלקולאַטאָר איז אויסגעלאָשן.
2. געפינט דעם דעקל פונעם באַטעריע־אָפּטייל אויף דער הינטערשטער זייט פונעם קאַלקולאַטאָר.
3. Carefully slide or unscrew the cover to open it.
4. Insert the AAA battery, ensuring the correct polarity (+/-) as indicated inside the compartment.
5. פאַרבייַטן די באַטאַרייע אָפּטייל דעקן סיקיורלי.

ערשט מאַכט אויף

דרוק די ON/C key to turn on the calculator. The display should show '0' or a previous calculation result. If the display is dim or blank, ensure the battery is correctly installed and that there is sufficient light for the solar panel.

Display and Direct Algebraic Logic (D.A.L.)

The calculator features a 2-line LCD display, showing both the calculation entry and the result simultaneously. The דירעקטע אַלגעברעישע לאָגיק (DAL) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

יקערדיק אָפּעראַטיאָנס

• אַדיציע, סובטראַקציע, מולטיפּליקאַציע, דיוויזיע: אַרייַן נומערן און נוצן די +, -, ×, ÷ שליסלען. דרוק = פֿאַר דעם רעזולטאַט.
• קלאָר איינטריט/אַלץ קלאָר: דרוק ON/C once to clear the current entry. Press it twice to clear all calculations and memory (except independent memory).

Scientific Functions (273 Functions)

The calculator supports a wide range of scientific functions. Many keys have secondary functions, accessed by pressing the צווייטע פ. קנעפל ערשט, דערנאך די געוואונטשענע פונקציע קנעפל.

• טריגאָנאָמעטריק פאַנגקשאַנז: זינד, קאָס, טאַן און זייערע אומגעקערטע פונקציעס (arc sin, arc cos, arc tan).
• לאָגאַריטמישע פונקציעס: קלאָץ (common logarithm), ln (נאַטירלעכער לאָגאַריטם).
• כוחות און וואָרצלען: x², √, יˣ.
• פאַקטאָריאַלס: n!
• Reciprocals: 1/x
• היפּערבאָלישע פונקציעס: היפּ (hyperbolic sine, cosine, tangent).

זכּרון פאַנגקשאַנז

The calculator includes eight temporary memories, one independent memory (M+, M-, רקל מ), and one last answer memory (ANS).

• קראָם (STO): Stores a value into a variable (A-F, X, Y).
• RCL (צוריקרופן): Recalls a value from a variable.
• M+ / M-: Adds/subtracts the displayed value to/from the independent memory.
• אַנס: דערמאָנט זיך דאָס רעזולטאַט פֿון דער פֿריִערדיקער חשבון.

סטאַטיסטישע פונקציעס

The calculator supports 1-variable and 2-variable statistics, along with six regression types.

1. דרוק מאָדע צו אויסקלייַבן STAT מאָדע.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the DATA CD שליסל.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (העקס), Binary (BIN), Decimal (DEC), Octal (אקטאבער), and Pentadecimal (פּען) bases.

• Use the dedicated keys for base conversions (e.g., →HEX, →BIN).
• Logical operations like AND, OR, NOT, XOR, and XNOR are also available.

Equation Editing & Playback

The calculator allows for editing previously entered equations and multi-line playback. Use the arrow keys to navigate through entries and make corrections.

היים שליסל

די היים key allows users to return to the initial calculation screen, clearing any previously entered data or settings without turning off the calculator.

Protective Hard Cover

The calculator comes with a protective hard cover. Always use this cover when the calculator is not in use to prevent scratches, dust accumulation, and accidental damage to the display and keys.

מאַכט מקור

The EL-531TGBBW utilizes Twin Power, meaning it operates on both solar energy and a AAA battery. Ensure the solar panel is exposed to light for optimal performance and to extend battery life. Replace the AAA battery when the display becomes dim or unresponsive in low light conditions.

טראָובלעשאָאָטינג

• דיספּליי איז ליידיק אָדער טונקל: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• פאַלשע רעכענונג רעזולטאַטן: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press באַשטעטיק (located on the back, may require a thin object like a paperclip) to return the calculator to its default settings. Note that resetting will clear all memory contents.
• Calculator does not respond to key presses: Ensure the calculator is turned on. If it remains unresponsive, try removing and reinserting the battery, or perform a reset.
