Blank Display
When the terminal display screen does not show correct or clearly readable
information:
• Check terminal power connection.
• Remove and reapply power to the terminal.
• Check all cable connections and verify that the telephone line is properly
connected.
• If the problem persists, contact your local Verifone service provider.
Terminal Does
Not Dial Out
Use the following steps when the terminal does not dial out:
• If you are using a telephone connection, check if the telephone line is plugged
correctly in the terminal port and in the telephone line socket.
• Check that the telephone line is working by plugging it into a working
telephone and listening for a dial tone.
• Replace the telephone cable that connects the terminal with a cable you know
is working correctly.
• Verify that a modem profile is present. The modem will not function without a
modem profile.
