ساتنه
پاکول
د کیلکولیټر پاکولو لپاره، په نرمۍ سره یې په نرم، وچ ټوکر سره پاک کړئ. د کثافاتو پاکوونکي، محلولونه، یا لوند ټوکر مه کاروئ، ځکه چې دا کولی شي کیلکولیټر ته زیان ورسوي.asing یا داخلي برخې.
ذخیره کول
When not in use for extended periods, store the calculator in a cool, dry place away from direct sunlight and extreme temperatures. Keep it in its protective cover to prevent scratches and damage.
د بیټرۍ پاملرنه
If the calculator will not be used for a very long time, it is advisable to remove the LR44 battery to prevent potential leakage and damage to the device.
د ستونزو حل کول
د ښودلو مسلې
- خالي ښودنه: Check battery level. Replace the LR44 battery if necessary. Ensure sufficient light for solar operation.
- کمزوری ښکاره کول: This may indicate a low battery. Replace the LR44 battery.
Incorrect Calculations
- ناسمې پایلې: Verify the input method (D.A.L.) and ensure all values are entered correctly. Check if the calculator is in the correct mode (e.g., DEG/RAD for trigonometric functions, STAT mode for statistics).
- د تېروتنې پیغام: Refer to the calculator's on-screen error codes (if any) for specific issues. Common errors include division by zero or invalid function arguments.
د کیلکولیټر بیا تنظیم کول
If the calculator behaves erratically or freezes, a reset may resolve the issue. Locate the small reset button (often on the back or side, requiring a thin object like a paperclip to press) or perform a soft reset via the چمتو کول menu. Note that resetting may clear all memory and settings.
