EMU pushbutton status indicators
The pushbutton status indicators display error conditions and the state of the audible alarm.
• When an error condition exists, the top pushbutton status indicator is On.
For a single error condition, the status indicator is On until the error condition is viewed.◦
◦ For multiple errors, the status indicator is On until the last error condition is viewed.
• The bottom pushbutton indicator is On only when the alarm is muted or disabled.
Audible alarm operations
Whenever an error condition exists, the audible alarm automatically sounds until all errors are
corrected. You have the option of either muting or disabling the alarm.
• Disabling the audible alarm prevents it from sounding for any error condition.
• Muting the alarm silences it for the existing condition, but any new condition causes the alarm
to sound.
Audible alarm patterns
The audible alarm sound pattern differs depending on the type of error condition. See
Table 12 (page 30) for the duration and the approximate relationship of these alarms. The most
severe, active error condition controls the alarm pattern.
