A medical system wherein multiple medical devices are connected to a system controller
which controls the medical devices via communication lines is arranged such that
in the event that trouble occurs, a user operates a maintenance button, which causes
the system controller to display multiple trouble items relating to the actions
of the medical devices on a display panel, and the user specifies a trouble item
matching the currently-occurring trouble from the displayed multiple trouble items,
whereby the system controller performs estimation processing for recovering from
the specified trouble item and displays countermeasures information for recovering
from the trouble item based on the estimation processing, and the user performs
processing following the displayed countermeasures information, thereby enabling
trouble to be efficiently recovered from.
