are
tested
by
activating
the
ANNUNCIATOR TEST switch, located on the copilot's
subpanel near the caution/ advisory panel. The system is
protected by the 5-ampere circuit breakers placarded

annunciators are automatically reset to
maximum brightness if:
(1) Both generators are not producing power (or
turned OFF) with MASTER SWITCH ON.
(2) The INSTRUMENT PANEL light switch is
rotated clockwise.
(3) The MASTER light switch is off.
