In order to prevent unauthorized use, Moneris recommends locking the terminal screen when:
your terminal is unattended, for example, when you are away from the cash register area;
your business is closed. Leave the terminal powered on and lock the screen.
To lock the screen:
Think of a lock code you will remember (using 4 to 10 digits).
You cannot use consecutive numbers (such as 1234) or repeating numbers (such as 1125).
On the Main menu, tap Screen Lock.
The “Please enter a temporary lock code for this device” prompt appears.
Enter the lock code you determined in step 1, then tap OK.
The screen is locked.
To unlock the screen:
enter the same lock code you used to lock the screen, or
enter your user ID and passcode.
