How to use
Turn the calculator on using the power key and enter numbers and operations via the keypad. Use dedicated function keys for trigonometric operations (sin, cos, tan), logarithms (log) and exponentiation or root calculations. Follow standard mathematical order of operations when combining functions and operators; parentheses are used where supported by the device to group subexpressions. After completing calculations, use the clear or reset key to remove the current entry or reset the device as needed.
Usage recommendations
For accurate trigonometric results, confirm the calculator's angle mode (degrees or radians) before performing calculations. Replace batteries promptly when display dimming or unreliable operation appears. Keep the device in a protective case or pouch to avoid key wear and maintain keypad legibility.
