feature, enter the Function menu from the home screen by pressing the

and then go to “Settings -> Security -> PIN Code”. Every time you need to change the settings, it is 

required to input the PIN code first (default PIN code: 1234, preset by the dealer).   

With this feature enabled, you will need to enter the correct PIN code prior to operating the terminal after

reset the PIN code. To change the PIN code, go to “Settings -> Security -> ChangePIN” from the home 

screen, and input the correct current PIN code prior to changing the code.
