Product Information

The DR-120R, DR-210R, and DR-270R are calculators that come with an input buffer that can hold up to 16 key operations, allowing users to continue inputting even while another operation is being processed. The DR-210R and DR- 270R also have a backup battery. The calculators have a switch for toggling between printing and non-printing modes. They also have a power-off function that triggers after about 30 minutes of non-operation. The calculators are available in English, Spanish, and French.

Product Usage Instructions

Power Supply

Make sure the power plug is connected to the calculator before use. The auto power-off function will be triggered after about 30 minutes of non-operation. To restore power, turn the Function Selector to OFF then ON or hold down the v(ON) button. If you are using the DR-210R or DR-270R, make sure to replace the back-up battery when the low battery icon appears. If you experience any unusual symptoms while using the calculator, such as skin irritation or a strange odor, stop using it immediately and consult with your physician.

Input Buffer

The input buffer of this calculator holds up to 16 key operations, allowing you to continue inputting even while another operation is being processed.

Replacing the Back-up Battery

If you are using the DR-210R or DR-270R, follow these steps to replace the backup battery:

1. Insert a thin, pointed non-metal object (such as a toothpick) into the hole and remove the old battery. Do not use a lead pencil.
2. Wipe off the surface of a new battery with a soft, dry cloth.
3. Load the new battery into the calculator so that its positive (+) side is facing up.
4. After confirming that the power plug is connected, press the RESET button.

Replacing the Printer Ribbon

To replace the printer ribbon, use a Type RB-02-A (black/red) ribbon and follow these steps:

1. Open the printer cover.
2. Remove the old ribbon by pulling it out to the left.
3. Install the new ribbon by inserting it from the right side and pressing it down until it clicks into place.
4. Close the printer cover.

Switching between Printing and Non-Printing Modes

The calculator has a switch for toggling between printing and non-printing modes. To switch to printing mode, set the ITEM switch to PRINT. To switch to non-printing mode, set the ITEM switch to OFF or ON.

Decimal Place Selector

The calculator has a Decimal Place Selector that allows you to set the number of decimal places displayed. You can choose from several options including F (floating decimal), CUT (cut off to the number of decimal places specified by the Decimal Place Selector setting), UP (round up to the number of decimal places specified by the Decimal Place Selector setting), and 5/4 (cut off or round up to the number of decimal places specified by the Decimal Place Selector setting).

Example Calculation

Here is an example calculation:

• 100 400 -) 300 500 700 ON, F 100 + 400 + 300 – : 200 100 500 200 200 500 +: 700 700
