Depending on when and where you are using your Reveal imager you may want to adjust the display's brightness.
The default setting for your Reveal is 90% brightness. The level can be adjusted to any level between 10% and 100%. We could go below 10%, but then you wouldn't be able to see it!
To adjust these settings you must locate the Display option in SETTINGS. You can find it here:
Menu > Device > Power > Display
