Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the malfunction memory menu in
the control system (
page 118) displays
both cleared and uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset knob.
Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset knob (page 22) and are
then stored in the malfunction message
memory (

compilation of all the messages that may
appear in the display.
