3.10 Dimming
For outdoor Starburst technologies, the display can be dimmed and brightened manually.
This can also be done 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 time, 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 that the controller is set to have manual
brightness during daylight hours or control the dimming level through scheduling.
To change the dimming, refer to the software operator’s manual (Venus 1500, ED 9067;
Venus 4600, ED 4602).
3.10.1 Light Detector Installation - Venus 1500
