Q: What should I do if the magnetic strip card reader is not working?
A: First check to see if the magnetic strip card has been oriented and read properly, the
proper use of the magnetic strip card reader is outlined in Figure 9 . Then attempt to
use another card for the transaction instead to determine whether the problem is a
defective card. Last of all manually enter the card information to process the
transaction and confirm that the device has malfunctioned. If none of the above
steps resolve the problem, contact an agent from your local vendor to repair the
device.
Q: What should I do if there a transaction error when using a magnetic strip card?
A: If a magnetic strip card is properly read by the card reader but the device indicates
that there is a transaction error or that the card is not supported, attempt to use the
IC card reader for the transaction instead or consult the service provider that issued
that card to resolve the problem. Before attempting to use a magnetic strip card,
make sure that the contactless card module is not operating simultaneously and that
the device is not near any object producing a strong electromagnetic field. Those
conditions may interfere with the device when it attempts to read the magnetic strip
card.
Communication modules
Q: What should I do if the USB port is not working?
A: First confirm that there are no foreign objects present in the USB port and that the
USB cable is fully plugged into the port. Also make sure that the cable used follows
USB specifications, attempt to use another cable if possible. Check to see if the USB
drivers are present and up to date.
Q: What should I do if there are errors while using the USB port?
A: The USB cable of D180 can only charge but not communicate, so use a third-party USB
cable. Do not use an USB hub, directly attach the cable to whatever device is being
linked.
Q: What should I do if there are errors while using the Bluetooth module?
A: First confirm the Bluetooth module on the D180 and any device you are attempting to
pair is turned on. Check to see whether the linked device is in range and that there
are no objects impeding the signal. Also see if the device is properly broadcasting
and there are no objects with the same name. Finally confirm that the password you
are using is correct. If none of this works, attempt to repair after restarting the
Bluetooth module.
