cards are not allowed for access.	2)	Check if there is a registered, but disallowed card in the PC.
	3)	For an unregistered card, try to enter it again and save to the PC before
		transferring to the device.
	4)	The Mass Transfer/Group Transfer function of the PC application will delete
		all card data in the device before transferring the PC data to the device. As
		such, if you usually register one card on a daily basis, you may not save it
		to the PC but transfer to the device, which causes unsaved card numbers
		not to be registered with the device in the operation of a mass-transfer.
	5)	If this is not the case, the problem may be caused by the defective of an

	3)	Check if the reader is properly connected to the system (device).
		- Check if the Wiegand communication lines between the reader and the
		system are properly established. (D0, D1)
		- The Wiegand communication line should be connected to GND. (A
		different power source may be fine but the earth-grounding point should
		be connected to GND of the device.)
	4)	If you find the output signal from the device but with severe noise when

		- Connect the shield wire and the spare wire of the cable to GND.
		- Use the repeater.
