Basic Operations
- Power ON/OFF: Press ON to turn on. Press [SHIFT] then OFF (usually above AC) to turn off.
- Clear Entry/All Clear: Use DEL to delete the last character. Press AC to clear the current entry or calculation.
- Shift Function: Press SHIFT to access the secondary functions printed above the keys (usually in yellow or orange).
- Alpha Function: Press ALPHA to access the alpha characters printed above the keys (usually in red).
- Replay Function: Use the replay buttons (directional arrows) to navigate through previous calculations or edit current entries.
Maintenance
Cleaning
To maintain the calculator's appearance and functionality:
- Wipe the exterior with a soft, dry cloth.
- For stubborn dirt, slightly dampen the cloth with water and a mild detergent, then wipe dry immediately.
- Do not use abrasive cleaners, solvents, or alcohol, as these can damage the casing and screen.
Battery Replacement
Refer to the "Battery Installation" section under Setup for detailed instructions on replacing the 4 AAA batteries. Replace batteries promptly when the display becomes dim or the calculator malfunctions.
Storage
When storing the calculator for extended periods, remove the batteries to prevent leakage and potential damage to the device.
Troubleshooting
- Calculator does not turn on:
- Check if the batteries are correctly installed with the proper polarity.
- Replace old or depleted batteries with new AAA batteries.
- Display is dim or unreadable:
- Adjust the display contrast in the settings menu ([SHIFT] + [MODE]).
- Replace the batteries if they are low.
- Calculator freezes or behaves erratically:
- Perform a soft reset by pressing the ON button.
- If the issue persists, perform a full reset via the settings menu ([SHIFT] + [MODE] and select reset option). Note that a full reset will clear all memory and settings.
- Incorrect calculation results:
- Ensure the calculator is in the correct mode for your calculation (e.g., Degree/Radian, Calculate mode).
- Check your input for errors.
- Perform a reset if necessary.
