4. Huolto
4.1. Puhdistus
Wipe the calculator's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing tai näyttö.
4.2. Pariston vaihto

5. Vianmääritys
- Tyhjä tai himmeä näyttö: Tarkista paristojen asennus. Vaihda paristot tarvittaessa.
- Väärät tulokset: Verify the input values and the selected mode (e.g., DEG/RAD). Ensure all previous calculations are cleared.
- Laskin ei vastaa: Yritä painaa RESET button (usually a small button on the back, requiring a thin object like a paperclip to press). This will clear all memory and settings.
- Virheilmoitukset: Consult the full product manual for specific error code meanings. Common errors include 'ERROR' for mathematical impossibilities (e.g., division by zero) or 'OVERFLOW' for results exceeding the calculator's capacity.
