DISPLAY BRIGHTNESS CONTROL
The BRT knob controls the dis-
play brightness.
Note: The display brightness
control provides full range dim -
ming to allow night operation in
no- or low-light situations. The
lower limit of the display bright -
ness may appear as an inoper -
ative tube during normal day -
light operation. It is therefore
advisable to check the BRT
knob setting during preflight
test.
To ensure maximum display
tube life, it is highly recom -
mended that the display be
operated at the lowest accept -
able brightness level.
