S Warnings messages, are the most urgent type of crew alerts and indicate
operational or aircraft system conditions that require immediate corrective action. All
warning messages are preceded by a triple chime and appear in red at the top of
the message area on ED1. For all warnings, the red MASTER WARNING lights will
flash. Some warnings also have an aural alert consisting of a unique tone and a
voice advisory. Warning messages cannot be removed from view, unless the
applicable failure has been rectified.
S Cautions messages, are less urgent than warnings and indicate operational or
aircraft system conditions that require prompt corrective action. All caution
messages are preceded by a single chime and appear in amber immediately below
the warnings in the message area on ED1. For all cautions, the amber MASTER
CAUTION lights will flash. Caution messages can be removed from view by using
the CAS button on the EICAS control panel.
S Advisories messages are used to show that a safe condition exists. They appear in
green at the top of the message area on ED2. Advisory messages cannot be
removed from view, unless the applicable system or switch has been deactivated or
deselected.
S Status messages indicate that an abnormal condition exists or that a low-priority
failure has occurred. They appear in white in the message area below the
advisories. Status messages can be removed from view by using the STAT button
on the EICAS control panel.
The most recent message appears at the top of its respective group of messages. A
message is automatically removed from EICAS when the associated condition no longer
exists. In this case, messages which appeared below the deleted message, each move up
one line. When a new fault occurs, the new message will move older messages down one
line.
If the number of warnings exceeds the message area (number of lines), then only the most
recent warning messages are displayed and a red PAGE 1/2 appears at the bottom of the
message area.
When more caution messages exist than can fit in the message area, a second page of
cautions will be created and a page 1 of 2 will be indicated in the top RH corner of primary
page. The CAS button on the EICAS control panel is then used to the next page of caution
messages.
S Caution messages can be removed from view by pressing the CAS button,
providing that both main generators are operating and on-line. A MSGS icon will
appear, advising the crew that the caution messages are out of view.
NOTE
If a new abnormal situation occurs, the corresponding caution
message will appear. To view all of the caution messages,
re-select the CAS button.

E. Synoptic Pages
Aircraft system information is presented in the form of synoptic pages. Synoptic pages
are simplified top--level schematic diagrams used for pilot and maintenance information.
The synoptic pages are dynamic displays of the aircraft systems status and operation
which includes all major components and parameter values. When a malfunction
occurs, the affected component and/or parameter value will change color. System flow
lines are green to indicate flow and white to indicate no flow. Status and malfunction
messages are also included on the synoptic pages.
The synoptic pages are selected by dedicated keys on the EICAS control panel (ECP)
or by using the STEP key to sequence through the pages (refer to figure 2). In normal
operation, the selected synoptic page will be displayed on EICAS display 2 (ED2).
Pressing the STAT key will return the status page to ED2.
NOTE
A description of each synoptic page is included in its related
