3. 설정

3.1 전원

The Sharp EL-W531 calculator operates using both solar power and a single AAA battery. The solar panel provides power in well-lit environments, while the battery ensures operation in low-light conditions.

3.2 배터리 설치/교체

1. 계산기가 꺼져 있는지 확인하십시오.
2. 계산기 뒷면에서 배터리 덮개를 찾으세요.
3. 작은 드라이버를 사용하여 덮개를 고정하는 나사를 조심스럽게 제거하십시오.
4. 덮개를 밀어서 떼어냅니다.
5. Remove the old AAA battery (if applicable) and insert a new AAA battery, ensuring correct polarity (+/-).
6. 배터리실 커버를 교체하고 나사로 고정합니다.

3.3 초기 전원 켜기

를 누르세요 켜짐/꺼짐 button to turn on the calculator. The display will show the last calculation or be cleared, depending on the previous state.
