Inputting Data

• In the SD Mode and REG Mode, the l key operates as the 7

key.

• Always start data input with !,(CLR) b(Scl) = to clear

statistical memory.

• Input data using the key sequence shown below. SD Mode: < REG Mode: <

• 77 inputs the same data twice.

• You can also input multiple entries of the same data using

!,(;).

Data Input Precautions

• While inputting data or after inputting data is complete, you can use

the f and c keys to scroll through data you have input. If you input multiple entries of the same data using !,(;) to specify the data frequency (number of data items) as described above, scrolling through data shows both the data item and a separate screen for the data frequency (Freq).

• Input the new value and then press the = key to replace the old

value with the new one. This also means that if you want to perform some other operation, you should always press the A key first to exit data display.

• Pressing the 7 key instead of = after changing a value on the

display registers the value you input as a new data item, and leaves the old value as it is.

• You can delete a data value displayed using f and c by pressing !l(CL). Deleting a data value causes all values following it to be shifted up.

• The message “Data Full” appears and you will not be able to input any more data if there is no memory left for data storage. If this happens, press the = key to display the screen shown below.

Press c to exit data input without registering

the value you just input.

Press b if you want to register the value

you just input. If you do this, however, you will not be able to display or edit any of the data you have input.

• After inputting statistical data in the SD Mode or REG Mode, you will be unable to display or edit individual data items any longer after perform either the following operations: changing to another mode; changing the regression type.

• Precision is basically the same as that described under “Calculation Range and Precision”, above.

• Calculations that use any of the functions or settings shown below require consecutive internal calculations to be performed, which can cause accumulation of error that occurs with each calculation.

18. Error Messages

The calculator will display an error message whenever an error occurs for any reason during a calculation.

• Press d or e to return to the calculation screen. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again.

• Press A to return to the calculation screen. Note that this also clears the calculation that contained the error.

Math ERROR Cause: • The intermediate or final result of the calculation you

are performing exceeds the allowable calculation range. • Your input exceeds the allowable input range. • The calculation you are performing contains an illegal mathematical operation (such as division by zero). Action: • Check the input values and reduce the number of digits.

• When using independent memory or a variable as the argument of

a function, make sure that the memory or variable value is within the allowable range for the function.

Stack ERROR Cause: The calculation you are performing has caused the capacity

of the numeric stack or the command stack to be exceeded. Action: • Simplify the calculation expression. • Try splitting the calculation into two or more parts.

Syntax ERROR Cause: There is a problem with the format of the calculation you

are performing. Action: Make necessary corrections.

19. Before Assuming Malfunction of the Calculator...

Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. Note that you should make separate copies of important data before performing these steps.

1. Check the calculation expression to make sure that it does not contain any errors.

2. Make sure that you are using the correct mode for the type of calculation you are trying to perform.

3. If the above steps do not correct your problem, press the O key.

4. Initialize all modes and settings. See “Initializing Calculation Mode and Setup”.

20. Replacing the Battery

Important: Removing the battery will cause all of the calculator’s memory contents to be deleted.

1. Press 1A(OFF) to turn off the

calculator.

2. Remove the cover as shown in the illustration and replace the battery, taking care that its plus (+) and minus (–) ends are facing correctly.

Screw Screw

3. Replace the cover.

4. Initialize the calculator. See “3. Initializing the Calculator”.

• Do not skip the above step!
