5.1 Operasi Aritmetik Asas
Perform standard calculations using the following keys:
- Penambahan (+): Masukkan nombor pertama, tekan +, masukkan nombor kedua, kemudian tekan =.
- Penolakan (-): Masukkan nombor pertama, tekan -, masukkan nombor kedua, kemudian tekan =.
- Pendaraban (×): Masukkan nombor pertama, tekan ×, masukkan nombor kedua, kemudian tekan =.
- Bahagian (÷): Masukkan nombor pertama, tekan ÷, masukkan nombor kedua, kemudian tekan =.
5.2 Fungsi Jelas
- ON/AC (All Clear): Clears all entries and calculations, resetting the calculator to zero. This also serves as the power on button.
- CE/C (Clear Entry/Clear): Clears the last entered number or the current calculation entry. Pressing it twice typically clears the entire calculation.
5.3 Fungsi Khas
- Peratustage (%):
- To calculate a percentage of a number: Enter the number, press ×, enter the percentage value, then press %. (e.g., 100 × 10 % = 10)
- Untuk menambah peratustage: Enter the number, press +, enter the percentage value, then press %. (e.g., 100 + 10 % = 110)
- Untuk menolak peratustage: Enter the number, press -, enter the percentage value, then press %. (e.g., 100 - 10 % = 90)
- Grand Total (GT): Accumulates the results of multiple calculations. After each calculation (e.g., pressing =), the result is added to the Grand Total memory. Press GT to display the accumulated total. Pressing GT lagi atau HIDUP/AC will clear the Grand Total memory.

6. Penyelenggaraan
6.1 Pembersihan
Untuk mengekalkan rupa dan fungsi kalkulator anda:
- Lap permukaan kalkulator dengan kain lembut dan kering.
- Untuk kotoran degil, sedikit dampen the cloth with water, then wipe dry immediately. Do not use chemical cleaners.
6.2 Penggantian Bateri
The calculator uses a small button-cell battery (e.g., LR1130 or similar, typically). While the calculator is primarily solar-powered, the battery provides backup in low light. If the display becomes dim or unresponsive in low light, the battery may need replacement.
Nota: Battery replacement may require opening the calculator casing, which should ideally be performed by a qualified technician to avoid damaging the device or voiding the warranty. Refer to the manufacturer's website or contact support for guidance.
