6.4 What to do in the event of a fault
Problems reading payment cards:
•
Insert the payment card again and press gently until you hear a click.
•
Perform an acquirer parameter session (see page 68).
•
Perform a € 0.01 transaction with another payment card. If this transaction is
successful, the customer’s payment card may be defective. If the transaction with the
other card does not succeed, there may be a problem with the terminal’s card reader.
•
Reset the payment terminal by disconnecting the power supply for 15 seconds.
First switch off the payment terminal and then remove the battery.

always correctly connected. Otherwise, it will not be possible to check the software version.
Resetting the Wi-Fi access point also affects other devices connected to the Wi-Fi network.
