Boulder Amplifiers 1012 DAC Preamplifier - Manual (Page 24)

DISPLAY
The display brightness may be set to any of 4 brightness levels.
To change the brightness level, press the DISPLAY pushbutton.
“DISPLAY 100%” will show in the display. Rotate the control until the
desired brightness is obtained such as “DISPLAY 50%.” The number in
the display is the relative brightness.
After several seconds of not changing the brightness level, the
display will return to the “VOLUME...” indication. You may also return
to controlling volume by again pressing the DISPLAY pushbutton.
With the display at a brightness less than that of 100%, any operation
of a pushbutton or the volume control will cause the display to go to full
brightness for several seconds, and then return to the desired brightness.
This ensures that if a function is changed, it will be noticed whether
intentional or inadvertent.
