Data Full

Cause

You are attempting to store sample data in the SD Mode or REG Mode

 

when the allowable number of data samples are already stored in memory.

 

 

Action

Keep the number of data samples within the allowable limit. For more

 

information, see “Maximum Number of Input Data Items” on page 38.

 

 

 

Go ERROR

 

 

 

 

Cause

A program (that you created in the PRGM Mode) has a “Goto n” command

 

without a corresponding “Lbl n” label.

Action

k 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. If one step does not correct the problem, move on to the next step. Note that you should make copies of important copies of important data before performing these steps.

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

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

3If the above steps do not restore normal operation, press the p key. The calculator will perform a self-check of its status as it starts up. If the calculator discovers a problem, it will return its calculation mode and setup to their initial defaults, and clear all data currently in memory.

4If step 3 does not restore normal operation, initialize all modes and settings by pressing !j(CLR)d(All)w.

Power Requirements

Your calculator has a TWO WAY POWER system that combines a solar cell with a button battery (LR44). Unlike solar cell-only calculators that operate only when light is present, a TWO WAY POWER system calculator keeps on operating even in the dark. (Of course, you will need enough light to be able to read the display contents.)

A Replacing the Battery

Dim display characters, especially when using the calculator where lighting is dim, or slow display response when you turn on the calculator indicates that button battery power is low. Replace the battery whenever you notice these symptoms. You should also regularly replace the battery at least once every three years, even if the calculator is operating normally.

Important!

Removing the button battery from the calculator causes independent memory contents and values assigned to variables to be cleared.
