It uses solar power to operate when there’s light and switches to the internal battery when lighting is dim. The auto power‑off feature turns the device off after a period of inactivity to conserve energy.

Key specs include a 12‑digit display, an angled viewing screen for reduced glare, a lightweight plastic body, three memory keys for storing values, and support for basic percentage calculations and repeated operations.

Use the memory keys to store and recall numbers (commonly labeled M+, M–, and MR). The repeat/equal function lets you repeat the last operation, making repetitive calculations quicker.

It's well suited for office math (invoices, totals, taxes), budgeting at home, classroom math tasks, inventory counting, and any scenario needing reliable 12‑digit precision.

Place the calculator on a flat desk, ensure it’s in a well‑lit area for solar power, and begin pressing keys. If lighting is insufficient, the built‑in battery will keep it running. Adjust the screen angle for comfortable viewing.

Keep the device dry and away from moisture, avoid exposing it to extreme temperatures, use dry hands when operating the keys, and recycle or dispose of batteries according to local guidelines.
