2. Enstalasyon
2.1 Debake
Lè w ap ouvri pake a, asire w ke bagay sa yo la:
- Sharp EL-506TSBBW Scientific Calculator
- Ka pwoteksyon difisil
- Manyèl Enstriksyon (dokiman sa a)
- 1 LR44 Battery (pre-installed)
2.2 Sous pouvwa
The EL-506TSBBW calculator utilizes a hybrid power system, combining solar power with a pre-installed LR44 battery.
- Enèji solè: The calculator will primarily use solar power when sufficient light is available. Ensure the solar panel, located above the display, is exposed to light during use.
- Pouvwa batri: The LR44 battery provides power in low-light conditions or when solar power is insufficient. The battery is pre-installed and typically does not require immediate replacement.
To turn the calculator ON, peze la ON/C key. To turn the calculator OFF, peze 2yèm F swiv pa OFF/C. The calculator will also automatically power off after a period of inactivity to conserve battery life.
3. Operasyon Enstriksyon
The Sharp EL-506TSBBW features a 12-digit, 2-line LCD display and 470 functions across 6 modes.
3.1 Display and Basic Input
The 2-line display shows the calculation entry on the upper line and the result on the lower line simultaneously. The Direct Algebraic Logic (D.A.L.) system allows for inputting equations exactly as they are written.
- Entering Numbers: Use the numeric keys (0-9) and the decimal point key (.).
- Operasyon debaz: Sèvi ak +, -, ×, ÷ for addition, subtraction, multiplication, and division.
- Egal: Peze = to execute the calculation.
- Efase Antre/Tout Efase: Peze ON/C once to clear the current entry. Press it twice to clear all calculations and settings.
- Kle Kay: La LAKAY key allows users to return to the initial calculation screen, clearing any previously entered data or settings.

3.2 Function Keys and Second Function (2nd F)
Many keys have a secondary function, indicated by text printed above the key, often in a different color (e.g., orange or yellow). To access these functions, press the 2yèm F kle a an premye, answit kle fonksyon ou vle a.
Fonksyon komen yo enkli:
- Fonksyon trigonometrik: peche, kos, tan ak fonksyon envès yo (2yèm F lè sa a peche-1, elatriye).
- Fonksyon Logaritmik: boutèy demi lit (baz 10) ak ln (logaritm natirèl).
- Pouvwa ak Rasin: x2, √, xy, y√x.
- Faktoryèl: n!
- Konstan: π (Pi).
3.3 Mòd Fonksyònman
The calculator features 6 operating modes. To change modes, press the MÒD key and select the desired mode using the numeric keys.
- Mòd NORMAL: Standard arithmetic and scientific calculations.
- STAT Mode: For statistical calculations (1, 2, and 3 variable statistics, 6 regression types).
- EQUATION Mode: Solves quadratic and cubic equations.
- COMPLEX Mode: For complex number calculations.
- MATRIX Mode: Performs matrix calculations.
- LIST Mode: For list-based calculations.
3.4 Fonksyon Memwa
The EL-506TSBBW includes various memory types to store and recall values.
- Independent Memory (M+): Ajoute valè ki parèt la nan memwa. M- soustrè. RCL M recalls.
- Temporary Memories: Eight temporary memories are available for short-term storage.
- Formula Memories: Four formula memories allow storage of frequently used formulas.
- Last Answer Memory (ANS): Stores the result of the previous calculation. Press ANS to recall.
3.5 Fonksyon avanse
The calculator supports a wide range of advanced mathematical and scientific functions:
- N-BASE Calculations: Perform calculations in Hexadecimal (HEX), Binary (BIN), Decimal (DEC), Octal (OCT), and Pentadecimal (PEN) bases.
- Differential and Integral Functions: Numerical differentiation and integration.
- Equation Editing & Playback: Review and edit previous equations.
- Normal Probability: Calculations related to normal distribution.
- Hyperbolic Trigonometric Functions: sinh, cosh, pwason.

4. Antretyen
4.1 Netwayaj
Pou kenbe aparans ak fonksyonalite kalkilatris la:
- Siye sifas kalkilatris la avèk yon twal mou epi sèk.
- Pou pousyè tè ki difisil pou retire, yon ti kras dampen the cloth with water. Do not use harsh chemicals, solvents, or abrasive cleaners.
- Avoid getting moisture into the calculator's openings.
4.2 Ranplasman batri
The calculator uses one LR44 button cell battery. When the display becomes dim or erratic in low light, it may be time to replace the battery.
- Asire w ke kalkilatris la etenn.
- Jwenn konpatiman pil la sou dèyè kalkilatris la.
- Carefully open the compartment using a small screwdriver if necessary.
- Retire ansyen pil LR44 la epi mete yon nouvo, asire polarite ki kòrèk la (+/-).
- Fèmen lòj batri a byen.
- Peze a ON/C key to turn on the calculator and verify functionality.
Nòt: Jete pil yo itilize dapre règleman lokal yo.
4.3 Depo
When not in use, store the calculator in its protective hard case to prevent damage to the display and keys. Avoid exposing the calculator to extreme temperatures, humidity, or direct sunlight for extended periods.
