బ్యాటరీ సంస్థాపన

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

1. కాలిక్యులేటర్ ఆఫ్ చేయబడిందని నిర్ధారించుకోండి.
2. కాలిక్యులేటర్ వెనుక భాగంలో బ్యాటరీ కంపార్ట్‌మెంట్ కవర్‌ను గుర్తించండి.
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. బ్యాటరీ కంపార్ట్‌మెంట్ కవర్‌ను సురక్షితంగా మార్చండి.

ప్రారంభ పవర్ ఆన్

నొక్కండి 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 డైరెక్ట్ ఆల్జీబ్రానిక్ లాజిక్ (DAL) system allows you to input elements of an expression in the exact order they appear when written, simplifying complex calculations.

ప్రాథమిక కార్యకలాపాలు

• Addition, Subtraction, Multiplication, Division: Enter numbers and use the +, -, ×, ÷ కీలు. నొక్కండి = ఫలితం కోసం.
• ఎంట్రీ క్లియర్/అన్నీ క్లియర్: నొక్కండి 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 2వ ఎఫ్ key first, then the desired function key.

• త్రికోణమితి విధులు: పాపం, కాస్, తాన్ మరియు వాటి విలోమ విధులు (arc sin, arc cos, arc tan).
• లాగరిథమిక్ విధులు: లాగ్ (common logarithm), ln (సహజ సంవర్గమానం).
• అధికారాలు మరియు మూలాలు: x² అంటే ఏమిటి?, √ √ ఐడియస్, yˣ.
• Factorials: n!
• Reciprocals: 1/x
• హైపర్బోలిక్ విధులు: hyp (hyperbolic sine, cosine, tangent).

మెమరీ విధులు

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

• STO (Store): Stores a value into a variable (A-F, X, Y).
• RCL (Recall): Recalls a value from a variable.
• M+ / M-: Adds/subtracts the displayed value to/from the independent memory.
• ANS: Recalls the result of the previous calculation.

గణాంక విధులు

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

1. నొక్కండి మోడ్ ఎంచుకోవడానికి STAT మోడ్.
2. Choose the desired statistical calculation type (e.g., 1-VAR, 2-VAR).
3. Enter data using the డేటా సిడి కీ.
4. Perform calculations using the statistical function keys.

N-Base Calculations

Perform calculations in Hexadecimal (హెక్స్), Binary (బిన్), Decimal (DEC), Octal (OCT), and Pentadecimal (పెన్) bases.

• Use the dedicated keys for base conversions (e.g., → హెక్స్, →బిన్).
• 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.

హోమ్ కీ

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

నిర్వహణ

క్లీనింగ్

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator. Avoid excessive moisture.

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.

శక్తి మూలం

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.

ట్రబుల్షూటింగ్

• డిస్ప్లే ఖాళీగా లేదా మసకగా ఉంది: Check battery installation and ensure sufficient light for the solar panel. Replace the AAA battery if necessary.
• తప్పు గణన ఫలితాలు: Verify the input sequence and selected mode (e.g., DEG/RAD/GRAD, Normal/STAT). Press రీసెట్ చేయండి (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.
