3.13 Dimming
For outdoor Starburst technologies, the display can dim and brighten manually. This happens under the
BRIGHTNESS menu through the Automatic option (if there is a light detector with the display).
At a certain level of ambient lighting, the lamps will dim. During the day, the lamps should be brightest
because they are competing with sunlight. In the evening and at night, they should be dimmer because
they are not competing with sunlight. If a light detector is not present, make sure the controller is set to
have manual brightness during daylight hours or control the dimming level through scheduling.
