Жайгашуу
Батарея орнотуу
Your TI-84 Plus calculator requires four AAA alkaline batteries for primary power and one silver oxide battery for memory backup. To install or replace batteries:
- Калькулятордун артындагы батарея бөлүкчөсүнүн капкагын табыңыз.
- Батарея уячаларын көрсөтүү үчүн капкакты жылдырып ачыңыз.
- Бөлүмдүн ичинде көрсөтүлгөндөй туура полярдуулукту (+/-) камсыз кылып, төрт AAA батарейкасын салыңыз.
- The silver oxide backup battery (typically a CR2032 or SR44SW) is located in a smaller, separate compartment. Use a small screwdriver to open this compartment and replace the battery if necessary. This battery preserves your memory settings and data.
- Батарея уясынын капкагын ордуна коюңуз, анын ордуна бекем чыкылдатыңыз.
Баштапкы күйгүзүү
Батареяларды орноткондон кийин, баскычын басыңыз ON button located at the bottom left of the keypad to power on your calculator. The screen should display the home screen or the last active application.

Негизги операциялар
The TI-84 Plus supports standard arithmetic operations, scientific functions, and advanced mathematical computations. Use the numeric keypad for input and the function keys for specific operations. The ENTER key executes commands.
Графикалык функциялар
The calculator allows you to define, save, graph, and analyze up to ten graphing functions simultaneously. Use the Y= key to enter functions, ТЕРЕЗЕ to set graph parameters, and ГРАФИК to display the graph. The split-screen option enables simultaneous viewing of a graph and its corresponding equation or table of values.

Техникалык тейлөө
Тазалоо
To ensure optimal performance and longevity, keep your calculator clean. Use a soft, dry cloth to wipe the screen and keypad. For stubborn dirt or dust between buttons, a soft brush or compressed air can be used. Avoid using harsh chemicals or abrasive materials, as these can damage the calculator's surface or screen.
Батареяны алмаштыруу
Replace the four AAA batteries when the display dims or the calculator fails to power on. The silver oxide backup battery typically lasts for many years and rarely needs replacement, as it primarily maintains memory when the main batteries are removed or depleted.
Проблемаларды чечүү
If your TI-84 Plus calculator experiences issues, consider the following common solutions:
- Calculator not turning on: Check if the AAA batteries are correctly installed and have sufficient charge. Replace them if necessary.
- Экран бош же күңүрт: Adjust the display contrast by pressing 2nd анда UP (for darker) or ылдый (for lighter). If this doesn't work, replace the AAA batteries.
- Calculator freezes or behaves erratically: Try resetting the calculator. This can often be done by pressing the RESET button on the back (requires a paperclip or similar pointed object) or by removing and reinserting the batteries. Note that a full reset may clear all memory.
- Graphing issues: Ensure your function equations are correctly entered and that the window settings (ТЕРЕЗЕ key) are appropriate for the function you are trying to graph.
