 You may wire a pull-down resistor to IC pin 4/5 to GND to stop stray noise pickup when the Velleman K8048 is disconnected. This isn't needed for normal and connected operation. You may wire a pull-down resistor to IC pin 4/5 to GND to stop stray noise pickup when the Velleman K8048 is disconnected.
