1. Important Precautions

• Never try to take the calculator apart.
• To clean the calculator, wipe it off with a soft cloth.
• Turn off the calculator after use. It is best to unplug from the AC outlet if you do not plan to use the calculator for a long
time.
• Unplugging the power cord from the AC outlet causes all values and settings of the calculator to be cleared. Make sure
you keep separate written copies of values and settings.
• Sample printouts shown in this manual were produced on the FR-2650T. Printouts produced by the FR-2650DT may
look slightly different.
• In no event will CASIO and its suppliers be liable to you or any other person for any damages, including any incidental or
consequential expenses, lost profits, lost savings or any other damages arising out of use of this calculator.
About the Input Buffer
The input buffer of this calculator can hold up to 12 key operations (both number entries and function commands), so you
can continue key input even while another operation is being processed.
RESET Button
• Pressing the RESET button deletes independent memory contents, tax rate settings, etc. Be sure to keep separate
records of all important settings and numeric data to protect against accidental loss.
• Press the RESET button on the back of the calculator to restore normal operation whenever the calculator does not
operate correctly. If pressing the RESET button does not restore normal operation, contact your original retailer or
nearby dealer.
