<p>Error notes are a warning to the user. They should only be used when the
user has tried to do something that may cause a considerable problem.</p>

<section id="GUID-A62B2AD0-BA1F-4112-9B61-25D29D3B1854"><title>Guidelines
for using error notes</title>       <p>Use an error note when the user does
something that may cause considerable harm immediately or later. For example,
the user gives a wrong PIN code. Repeating this couple of times would block
the SIM card.</p> <p>To keep error notes effective, they should be used very
sparingly. In most ordinary error cases, an <xref href="GUID-E449F309-F230-46F9-B777-EF64D0E3191D.dita">information
note</xref> should be used instead of an error note. It has a less aggressive
sound and graphics.</p>  <p>It should also be noted that if the information
to be given is such that the user must see and acknowledge it, a confirmation
query is a better component to use than a note. Then the user must press a
key to dismiss the information, and there is time to read and think about
the notification.</p>           </section>
