About the Input Buffer
Depending on the model, the calculator’s input buffer can hold up to 12 or 14 key operations (both number entries and function commands). This means you can continue key input even while another operation is being processed.
Back-up Battery (DR-250TM/270TM)
This calculator comes with a built-in memory backup battery that provides power to retain the values stored in memory when the calculator is not plugged into an AC power outlet. The memory backup battery requires periodic replacement, about once every 11 months. After that time, input data may change or be deleted while you are using the calculator. Refer to “Replacing the Battery” when replacing the battery.
Caution: Incorrectly replacing the battery creates the risk of explosion. Use a CR2032-type battery only. Dispose of used batteries according to the battery manufacturer’s instructions.
RESET Button
- Pressing the RESET button deletes calculation memory contents, independent memory contents, grand total memory contents, tax rate settings, time and date settings, data content 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.
