Signs the device may have been opened or altered
If anything appears suspicious, do not use the terminal and contact Practice by Numbers Customer Support immediately.

The Castles S1F2 terminal does not accept chip (inserted) cards.

Step 3: Insert the Receipt Paper Roll
Once you have verified the terminal, install the receipt paper:
Locate the paper roll inside the shipping box.
Open the printer compartment by pressing the sides of the paper cover and lifting it upward.
Insert the paper roll so the paper feeds over the contactless logo.
Close the cover securely until it clicks into place.
Your terminal is now ready for charging and setup.
