Chapter 4 “Replacing the keys”
You are free to change the layout of the keys except for the ten keys of the numeric keypad.
For example, frequently used keys can be made into larger double keys by replacing two
single keys with one double key.
This chapter explains how to replace single keys, double keys, quadruple keys, and
unused key covers on the keyboard.
Before replacing keys, put the POS terminal into standby mode
(system lamp off) by pushing the standby button.
