2-14-30. CAUTION LT Panel.
The CAUTION LT (caution light) panel is located on the
center instrument panel (16, fig. 2-1-4). It comprises of a
BRT-DIM switch and a TEST switch.
a.
BRT-DIM Switch. When the switch is placed to
BRT, the caution capsule will light to full intensity. When
moved to DIM, the caution capsules will not be as bright.
When the cockpit dome lights are on white, it is not pos-
sible to dim the master caution panel. If the white dome
light is selected while the caution lights are operating on
DIM, the caution lights will automatically switch to BRT
mode of operation.
b.
TEST Switch. When the switch is placed to
TEST, all the caution capsules on the master caution
panel and the two MASTER CAUTION lights illuminate
to faciliate checking the individual capsule lamps. When
released to OFF, the lamps in the MASTER CAUTION
lights and all the caution capsules extinguish. When the
PLT INST and CPLT INST lights rotary control switches
are active, and the VHF NAV and marker beacon VOL
switches are on, the test feature will also light all the
select legends on the MODE SELECT panel and the
MKR BCN indicator lights.
