NOTE
The BRT AUTO display brightness level is determined
by the amount of light detected by the photocell on
the front of the EBD. If a light is used to illuminate the
instrument panel, the photocell will respond, resulting
in a bright display. When this happens, use the manual
BRT ADJUST mode to reduce the brightness.

displayed in green to the left of the Bottom Knob (Figure 2-13).
To override the AUTO brightness setting, press the Bottom Knob once to switch to
the BRT ADJUST mode, and then rotate the Bottom Knob to set the brightness to the
desired level (Figure 2-14). To return to AUTO brightness control, press the Bottom
