Congratulations! You have just acquired the PLC270 desktop calculator with profit
feature from Lexibook
This calculator will allow you to perform standard calculations as well as advanced
functions such as percentage, memory, Tax calculation and quick profit analysis.

The "00" key allows you to quickly enter the hundreds. Example: Press "5", then the
"00" key and the calculator will display "500".
The "+/-" key allows you to change a positive number to negative, or vice versa. The
" – " sign appears to the left of the screen when the number displayed is negative.
The " ‹ "
key allows you to correct the last numbers entered. Press this key as many
times as required.
1. Percentage calculations
20€ + 6% tax = 21.2€
150€ minus 20% = 120€
Note: If you have pressed the wrong arithmetic function key (addition, subtraction,
multiplication, division), press the 'correct function' key immediately to
correct the mistake and proceed with the calculation.
2. Calculations using memory
Before saving a new value to the memory, the content must first be deleted by
pressing the 'MRC' key twice and then pressing the 'ON/C' key to delete all previous
calculations.
To add a value to the memory, enter the chosen number or calculation and then press
the 'M+' key. The result of the calculation is worked out and, if applicable, added to
the value in the memory.
When 'MEMORY' is displayed, it indicates that a value is stored in the memory.
To deduct a value from the memory, enter the chosen number or calculation, and then
press the "M-" key. The number entered (or the result of the calculation) is deducted
from the value stored in the memory.
