This section addresses common issues you might encounter with your Casio fx-115MS PLUS SR Scientific Calculator.

5.1 Calculator Does Not Turn On or Display is Blank

• Ṣayẹwo Imọlẹ: Ensure the solar panel is exposed to sufficient light.
• Batiri: If operating in low light or if the display remains blank, the battery may be depleted. Consider replacing the battery according to manufacturer instructions.
• Tun: A small reset button (often on the back) may be present. Use a thin, pointed object to press it. Note that this will clear all memory.

5.2 Aifọwọyi Tiipa

The calculator is designed to automatically shut off after a period of inactivity (approximately 6 minutes) to conserve power. This is a normal function. To resume operation, press the ON button. Be aware that calculations in progress may be lost upon automatic shut-off.

5.3 Wobbly Case

The slide-on hard case is designed for protection during transport. If the calculator feels wobbly when placed on a surface with the case underneath, it is due to the rounded design of the case. For stable operation, remove the case and place the calculator directly on a flat surface.

5.4 Incorrect Calculation Results

• Input Error: Carefully re-enter the calculation to ensure accuracy. Utilize the two-line display to verify your input.
• Awọn Eto Ipo: Check if the calculator is in the correct mode (e.g., DEG, RAD, GRD for angles; COMP for complex numbers).
• Iranti Ko: Clear all memory and variables if unexpected results persist.
