3.14 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.
