Check the Telephone Line
• Disconnect the telephone line from the VX 680 terminal and connect it to a
working telephone to check for a dial tone. If there is no dial tone, replace the
telephone cable.
• If the problem appears to be with the telephone line, check with the party you
are trying to call to see if their system is operational. If they are not
experiencing difficulties with their line, contact the telephone company and
have your line checked.
• If the telephone line works, contact your local VeriFone representative for
assistance.
