Following the list are explanations of the messages and remedies for reported problems.If your system displays one of except the messages marked below with an asterisk (*), write down the message and contactPanasonic Technical Support. If your system fails after you make changes in the Setup menus, reset the computer, enter Setup andinstall Setup defaults or correct the error.0200 Failure Fixed DiskFixed disk in not working or not configured properly.
