c. Annunciator System – General. In the
frontal view, the annunciator panels present rows of
small opaque rectangular annunciators. Word printing
on the respective indicator identifies the monitored
function, situation, or fault condition, but it cannot be
read until the annunciator is illuminated. Blank
annunciators (no word printing) are non-functioning
annunciators. The bulbs of all annunciator panels are
tested by pressing the annunciator test push-button
switch, placarded PRESS TO TEST, located on the
instrument panel on the right side of the warning
annunciator panel. The system is protected by a
7-1/2-ampere circuit breaker, placarded ANN POWER,
and a 5-ampere circuit breaker, placarded ANN IND,
located on the right sidewall circuit breaker panel. The
annunciators are dimmed when the MASTER light
switch is ON and the pilot's flight instrument lights are
illuminated.
(1) Annunciator Bright and Dim Mode. The
warning and caution annunciator panels and the
master warning and master caution annunciators
feature a bright and dim mode of operation. The dim
mode will be selected automatically whenever all the
following conditions have been met.
1. A generator is on line.
2. Overhead floodlights are OFF.
3. Pilot flight instrument lights are on.
4. The ambient light intensity in the
cockpit (as sensed by a photocell
located on the overhead control panel)
is below a preset value.
Unless all of these conditions are met, the bright
mode will be selected automatically.
d. Master Warning Annunciators (Red). Two
MASTER WARNING annunciators, one located on
each side of the glareshield, are provided to alert the
crew of a hazardous condition. Any time a warning
annunciator illuminates, the MASTER WARNING
annunciators will flash, and will remain flashing until
reset. If a new condition occurs, the annunciators will
be reactivated, and the applicable annunciator panel
annunciator(s) will illuminate.
e. Master Caution Annunciators (Yellow).
Two MASTER CAUTION annunciators, one located
on each side of the glareshield adjacent to the
MASTER WARNING annunciator, Figure 2-41, are
provided to alert the crew of a situation requiring the
crew's attention. Whenever a caution annunciator
illuminates, the MASTER CAUTION annunciators will
flash,
and
remain
flashing
until
the
MASTER
CAUTION annunciator is reset. If a new condition
occurs, the annunciators will be reactivated and the
appropriate annunciator(s) will illuminate.
f. Clocks.
(1) Description. A digital quartz chronometer
is mounted in the center of each control wheel,
Figure 2-22. Each quartz chronometer is a three-
function clock/timer that is controlled by two push-
button switches, placarded SELECT and CONTROL,
located directly below the four-digit liquid crystal
display.
(2) Operation. The SELECT button is
pressed to select the desired mode of operation. The
mode annunciator is displayed on the left side of the
mode identifiers, and advances to indicate each of the
following modes:
UT
– Universal or Greenwich Mean Time
