Be sure to keep physical records of all important data!  
The large memory capacity of the unit makes it possible to store large amounts of data.  
You should note, however, that low battery power or incorrect replacement of the batteries that  
power the unit can cause the data stored in memory to be corrupted or even lost entirely. Stored  
data can also be affected by strong electrostatic charge or strong impact. It is up to you to keep  
back up copies of data to protect against its loss.  
Since this calculator employs unused memory as a work area when performing its internal calculations,  
an error may occur when there is not enough memory available to perform calculations.To avoid such  
problems, it is a good idea to leave 1 or 2 kbytes of memory free (unused) at all times.

The calculator is equipped with flash memory for data storage. It is recommended that you always  
backup your data to flash memory. For details about the backup procedure, see “Using the Memory  
Manager” (page 11-1) in the separate Software User’s Guide.  
You can also transfer backup files (page 11-11) to a computer by establishing a USB connection  
between the calculator and a computer. For information about transferring files from a computer to  
the calculator, see “Chapter 13 Data Communication” in the separate Software User’s Guide.  
E-5  
Handling Precautions  
• Your calculator is made up of precision components. Never try to take it apart.  
• Avoid dropping your calculator and subjecting it to strong impact.  
• Do not store the calculator or leave it in areas exposed to high temperatures or humidity, or large  
amounts of dust. When exposed to low temperatures, the calculator may require more time to  
display results and may even fail to operate. Correct operation will resume once the calculator is  
brought back to normal temperature.  
• Your calculator supports use of both alkaline batteries and rechargeable nickel-metal hydride  
batteries. Note that the amount of operation between charges provided by nickel-metal hydride  
batteries is shorter than the life of alkaline batteries. Use only batteries that are specifically  
recommended for this calculator.  
• Replace the batteries once every one year regardless of how much the calculator is used during  
that period. Never leave dead batteries in the battery compartment. They can leak and damage  
the unit. Immediately remove nickel-metal hydride batteries from the calculator after their charge  
is used up. Leaving uncharged nickel-metal hydride batteries in the calculator can cause them to  
deteriorate.  
• Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.  
• Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft, dry  
cloth, or with a cloth that has been moistened with a solution of water and a neutral detergent and  
wrung out.  
• Always be gentle when wiping dust off the display to avoid scratching it.  
• In no event will the manufacturer and its suppliers be liable to you or any other person for any  
damages, expenses, lost profits, lost savings or any other damages arising out of loss of data  
and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to you to  
prepare physical records of data to protect against such data loss.  
• Never dispose of batteries, the liquid crystal panel, or other components by burning them.  
• Be sure that the power switch is set to OFF when replacing batteries.  
• If the calculator is exposed to a strong electrostatic charge, its memory contents may be  
damaged or the keys may stop working. In such a case, perform the Reset operation to clear the  
memory and restore normal key operation.  
• If the calculator stops operating correctly for some reason, use a thin, pointed object to press  
the RESTART button on the back of the calculator. Note, however, that this clears all the data in  
calculator memory.  
• Note that strong vibration or impact during program execution can cause execution to stop or can  
damage the calculator’s memory contents.  
• Using the calculator near a television or radio can cause interference with TV or radio reception.  
• Do not use this calculator in areas where the use of electronic devices is prohibited.  
• The liquid crystal panel used for the calculator’s LCD incorporates high-precision technology for  
an effective pixel yield of at least 99.99%. Even at this level, some pixels may fail to light or may  
remain lit at all times. This is normal and does not indicate malfunction.  
• Due to limitations of the LCD equipped in this calculator, graphic images may not appear as they  
do on your computer display in terms of color, etc.  
• Before assuming malfunction of the unit, be sure to carefully reread this User’s Guide and ensure  
that the problem is not due to insufficient battery power, programming or operational errors.

Display Brightness and Battery Life  
I Display Brightness  
You can select a display brightness value in the range of 1 (least bright) to 5 (brightest). The  
initial factory default brightness setting is 3.  
The brightness level will change to 1 (least bright) automatically if you do not perform any  
operation on the calculator for about 30 seconds. Performing an operation will return display  
brightness to the level specified by the current setting value.  
For details about how to configure the display brightness setting, see “Chapter 12 System  
Manager” in the separate Software User’s Guide.  
I Battery Life  
Battery life is affected by the display brightness and backlight duration settings. Battery life  
is also affected by how the calculator is used. Using a program to execute a long series of  
calculations, for example, will shorten battery life.

Restart and Reset  
S Restart  
Should the calculator start to act abnormally, you can restart it by pressing the RESTART  
button. Note, however, that you should only use the RESTART button only as a last resort.  
Normally, pressing the RESTART button reboots the calculator’s operating system, so  
programs, graph functions and other data in calculator memory is retained.  
RESTART button  
Important!  
The calculator backs up user data (main memory) when you turn power off and loads the  
backed up data when you turn power back on.  
When you press the RESTART button, the calculator restarts and loads backed up data.  
This means that if you press the RESTART button after you edit a program, graph function,  
or other data, any data that has not been backed up will be lost.  
S Reset  
Use reset when you want to delete all data currently in calculator memory and return all  
mode settings to their initial defaults.  
Before performing the reset operation, first make a written copy of all important data.  
For details, see “Reset” (page 12-4) in the separate Software User’s Guide.
