3. Configuração
3.1. Instalação da bateria
The calculator operates on a Twin Power system, utilizing both solar power and a single LR44 button cell battery. The battery is typically pre-installed. If the display becomes dim or unresponsive in low light, the battery may need replacement.
- Ensure the calculator is turned OFF.
- Localize o compartimento da bateria na parte traseira da calculadora.
- Use a small screwdriver to open the compartment cover.
- Remova a bateria LR44 antiga e insira uma nova, certificando-se da polaridade correta (+/-).
- Recoloque a tampa do compartimento e fixe-a com o parafuso.
3.2. Ligação inicial
Pressione o LIGADO/C button to turn on the calculator. The display will show the initial screen. If the display is blank, ensure sufficient light for solar power or check the battery.

4. Instruções de operação
4.1. Operações básicas
Realize cálculos aritméticos padrão usando as teclas numéricas e os operadores (+, -, x, ÷). Imprensa = to get the result. The calculator uses Direct Algebraic Input Logic (D.A.L.), allowing you to input equations in a natural order.
4.2. EscreverView Mostrar
A escritaView display allows you to enter and view mathematical expressions and symbols as they appear in textbooks. This 96 x 32 dot matrix display supports up to 4 lines of content. Use the cursor keys to navigate and edit expressions.
4.3. Scientific Functions
Access various scientific functions using the dedicated keys and the 2º F key for secondary functions. These include:
- Funções trigonométricas: sin, cos, tan, and their inverse functions (sin-1, porque-1, bronzeado-1).
- Hyperbolic Functions: hyp, and their inverse functions.
- Logarithmic and Exponential Functions: log, ln, 10x, ex.
- Funções de energia e raiz: x2, √, xy, y√x.
- Factorial, Permutations, Combinations: n!, nPr, nCr.
- Constantes: Pi (π), EXP.
4.4. Statistical Functions
The calculator supports statistical calculations for 1-variable and 2-variable data. To enter statistical mode, press MODO and select the appropriate statistical option. Functions include:
- Mean value (x̄, ȳ)
- Standard deviation (σx, σy, sx, sy)
- Sum of values (Σx, Σy, Σx2, Σy2, Σxy)
- Regression analysis (linear, quadratic, exponential, etc.)
4.5. Funções da memória
The calculator has 9 independent memories (A-F, X, Y, M) to store and recall values. Use the STO key to store a value and the RCL key to recall a stored value. M+ e M- are used to add or subtract values from the independent memory M.
4.6. Angle Units
The calculator supports three angle units: Degrees (DEG), Radians (RAD), and Gradians (GRAD). Press the DRG key to cycle through these units or use the CONFIGURAR menu to select the desired unit.
4.7. Number Systems
Perform calculations and conversions in different number bases: Decimal (DEC), Hexadecimal (HEX), Octal (OCT), Binary (BIN), and Pentary (PEN). Use the dedicated keys or the MODO menu to switch between number systems.
4.8. Shortcut Keys (D1-D4)
The four shortcut keys (D1, D2, D3, D4) can be programmed to quickly access frequently used functions. Refer to the calculator's on-screen setup menu for instructions on how to assign functions to these keys.
