Denso Wave PR450UDM Manuale Utente

Problem

Communication with IC card is blocked.

• Check that the card is correctly placed in the cradle. (Refer to “Handling of Card” in page 13.)
• Make sure that the card you are using is supported as a readable card. (Refer to “Specifications”

in page 14.)

• Check that the PR-450UDM is free from any noise source that may adversely affect its operation.

If required, you should take some appropriate noise prevention measures. (Refer to “Notes for
placing the PR-450UDM” in page 5.)

• If the PR-450UDM is placed near a metal object, such as on a steel desk or computer with a

metal housing, move the device away from that metal object. (Refer to “Notes for placing the
PR-450UDM” in page 5.)

If the wireless networking with IC card cannot be regained even if you have tried all the above solutions,
there may be an error in the application running on the PR-450UDM. Make sure that:

•  The right method and protocol are selected for the transmission.
•  The communication protocol with the upper unit has been successfully processed.
•  The carrier is set to the ON position.
•  The communication with IC cards has been successfully processed.
