Setup

Powering On

The TI-30X IIS calculator is dual-powered, utilizing both solar energy and a lithium metal battery (included). To power on the calculator, press the ON button located at the bottom left of the keypad.

Initial Setup

Upon first use, or after a prolonged period of inactivity, the calculator should power on automatically when exposed to light or when the ON button is pressed. No specific initial setup is required beyond ensuring adequate light for solar power or sufficient battery charge.

Battery Installation/Replacement

The calculator uses 1 Lithium Metal battery. If the display becomes dim or unresponsive in adequate light, the battery may need replacement. Refer to the back of the calculator for the battery compartment. Ensure proper polarity when installing a new battery.

Operating Instructions

Basic Operations

Perform standard arithmetic operations using the number keys and operators (+, -, ×, ÷). Press ENTER to calculate the result.

Two-Line Display

The upper line of the display shows the entered expression, while the lower line shows the result. This allows for easy review and editing of calculations.

Scientific Functions

Access scientific functions such as logarithms (LOG, LN), trigonometric functions (SIN, COS, TAN), and their inverses using the corresponding keys. Many functions require pressing the 2nd key first to access the secondary function printed above the button.

Statistical Calculations

The calculator handles 1- and 2-variable statistical calculations. Use the DATA key to enter data points and the STATVAR key to access statistical variables.

Angle Modes

Switch between three angle modes: Degrees (DEG), Radians (RAD), and Grads (GRAD). The current mode is indicated on the display. Press the DRG key to cycle through the modes.

Fractions and Conversions

Enter and perform calculations with fractions using the n/d key. Convert between fractions and decimals, or mixed numbers and improper fractions, as needed.

Memory Functions

Store and recall values using the memory keys (STO, RCL). The calculator has multiple memory registers.

Error Messages

If an error occurs, an error message will appear on the display. Refer to the full user guide for a list of error codes and their meanings.

Maintenance

Cleaning

To clean the calculator, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or screen.

Storage

When not in use, store the calculator in its protective slide case to prevent scratches and damage. Avoid exposing the calculator to extreme temperatures or humidity.

Battery Care

While the calculator is solar-powered, it also relies on a lithium metal battery. If storing the calculator for an extended period, ensure it is in a well-lit area to allow the solar panel to maintain the battery charge. If the battery is completely depleted, replace it as described in the Setup section.

Troubleshooting

• Calculator does not turn on:
  • Ensure the calculator is exposed to sufficient light for solar power.
  • Check the battery. If the battery is low or depleted, replace it.
  • Press the ON button firmly.
• Display is dim or blank:
  • Move the calculator to a brighter area.
  • Replace the battery if the issue persists.
• Incorrect results:
  • Verify the input values and the order of operations.
  • Check the current angle mode (DEG, RAD, GRAD) if performing trigonometric calculations.
  • Clear the calculator's memory by pressing 2nd then RESET.
• Buttons are unresponsive:
  • Ensure the calculator is clean and free of debris around the buttons.
  • If the calculator has been dropped or subjected to impact, internal damage may have occurred.
