2. About Calculation Steps

• The step indicator shows the number of the step currently shown on

the display.

• A finalize key operation and the result it produces is also a step. See

“Finalizing a Calculation” below.

• Steps continue to be accumulated in Calculation Memory until you press

the Q key or until 300 steps are accumulated, even if a finalize key

is pressed.

• Review and GO TO can be used to view only the first 300 steps in

Calculation Memory, even if there are more steps. (DJ-120D Plus)

• Review and GO TO cannot be performed while an error indicator is

displayed. (DJ-120D Plus)

• Pressing the Q key clears all steps from Calculation Memory and

restarts the step count from 1.

3. Finalizing a Calculation

Finalizing a calculation means performing a key operation that produces

a calculation result. Pressing any of the following keys finalizes a

calculation: =, &, l, m.

4. Power Supply

Two-Way Power System provides power even in complete darkness.

5. Auto Power Off Function

This calculator is not equipped with an OFF switch. Instead, it switches

power off automatically about six minutes after the last key operation is

performed. To restore power, press Q.

is in progress, press Q= to restore power. Doing so returns to the
