Sumber Kuasa
The Sharp EL-250S calculator operates on a dual power system: solar power and a single LR44 button cell battery. In well-lit conditions, the calculator primarily uses solar power. In dim lighting or when solar power is insufficient, it automatically switches to battery power.
Pemasangan/Penggantian Bateri
- Pastikan kalkulator dimatikan.
- Cari penutup petak bateri di bahagian belakang kalkulator.
- Menggunakan pemutar skru kecil, tanggalkan skru yang memasang penutup petak bateri dengan berhati-hati.
- Tanggalkan penutup.
- Remove the old LR44 battery (if replacing).
- Masukkan bateri LR44 baharu dengan bahagian positif (+) menghadap ke atas.
- Gantikan penutup petak bateri dan kencangkannya dengan skru.
Nota: Dispose of used batteries according to local regulations. Do not mix old and new batteries.

- The calculator will automatically turn off after approximately 7-10 minutes of inactivity to conserve power.
Basic Arithmetic Calculations
- Tambahan: Masukkan nombor pertama, tekan +, masukkan nombor kedua, tekan =.
- Penolakan: Masukkan nombor pertama, tekan -, masukkan nombor kedua, tekan =.
- Pendaraban: Masukkan nombor pertama, tekan ×, masukkan nombor kedua, tekan =.
- Bahagian: Masukkan nombor pertama, tekan ÷, masukkan nombor kedua, tekan =.
