Specifications Power Requirements: Built-in solar cell; button battery LR44 (GPA76) × 1 Approximate Battery Life: 3 years (based on one hour of operation per day) Operating Temperature: 0°C to 40°C (32°F to 104°F) Dimensions: 11.1 (H) × 80 (W) × 162 (D) mm 3/8Љ (H) × 31/8Љ (W) × 63/8Љ (D) Approximate Weight: 95 g (3.4 oz) including the battery Frequently Asked Questions k How can I perform input and display results the same way I did on a model that does not have Natural Textbook Display? Perform the following key operation: 1N(SETUP)2(LineIO). See "Configuring the Calculator Setup" on page E-5 for more information. k How can I change a fraction form result to decimal form? How can I change a fraction form result produced by a division operation to decimal form? See "Toggling Calculation Results" on page E-13 for the procedure. k What is the difference between Ans memory, PreAns memory, independent memory, and variable memory? Each of these types of memory acts like "containers" for temporary storage of a single value. Ans Memory: Stores the result of the last calculation performed. Use this memory to carry the result of one calculation on to the next. PreAns Memory: Stores the result of calculation before the last one. PreAns memory can be used only in the COMP Mode. Independent Memory: Use this memory to totalize the results of multiple calculations. Variables: This memory is helpful when you need to uses the same value multiple times in one or more calculations. k What is the key operation to take me from the STAT Mode or TABLE Mode to a mode where I can perform arithmetic calculations? Press N1(COMP). k How can I return the calculator to its initial default settings? Perform the following operation: 19(CLR)1(Setup)=(Yes) k When I execute a function calculation, why do I get a calculation result that is completely different from older CASIO calculator models? With a Natural Textbook Display model, the argument of a function that uses parentheses must be followed by a closing parenthesis. Failing to press ) after the argument to close the parentheses may cause unwanted values or expressions to be included as part of the argument. Example: (sin 30) + 15 v Older (S-VPAM) Model: s 30 + 15 = 15.5 Natural Textbook Display Model: b s 30 )+ 15 = 15.5 Failure to press ) here as shown below will result in calculation of sin 45. s 30 + 15 = 0.7071067812 E-30
