27 Help and error messages
27.1 Overview
The dental unit displays two types of safety messages: help messages and
error messages.
Help messages provide helpful information for the user. They are displayed,
for example, if you are using the unit or instrument incorrectly, or if the
function is not allowed for some reason. The help message disappears
automatically when the situation is corrected.
Error messages warn of a fault in the dental unit and require actions from the
user. To correct the error situation, and thus to close the error message,
follow the instructions in the message.
