Dimmer Control
The 6185-E is equipped with proprietary display dimming circuitry that
allows full range control of image luminance from the front panel. The
LEDs are present with or without the dimmer control, but the two
buttons that adjust the luminance of the display are optional.

Dimmer Control
The control buttons adjust the luminance of the image, which is not the
same as the brightness setting. Luminance refers to the actual intensity
of the light emitted from the monitor. Brightness refers to the
appearance of the image displayed – a range between dark and dazzling.
The backlights are controlled by the luminance control.
To adjust the luminance of the monitor:
Press and hold either one of the dimmer buttons until the luminance is
adjusted as desired.
•
The left dimmer button reduces the luminance and the right button
increases it.
•
The green LED blinks fast when you first press the button and slows
down as you reach the end of the adjustment range.
•
When you release the dimmer button for three seconds, the amber
LED blinks twice to indicate that your changes have been saved and
will be used each time the monitor is powered ON.
