4.1 Cabinet Specifications
Cabinets for the Daktronics outdoor LED digit displays are constructed of heavy-
gauge aluminum. Exact dimensions and weights for each model are listed in the
chart in Section 2. Hinged panels for servicing digits and indicators and for
component access are detailed in each model's mechanical specifications drawing.
4.2 Component Location and Access
For the front-access modules in this series, all internal electronic components and
digits can be reached by opening one of the hinged access doors on the front of the
display. Each door swings outward when the two screws on the display face panel
are removed, as shown in Figure 7. For front and opened views of the displays, refer
to your model's electrical and mechanical specifications drawings, listed in Sections
2.1 and 2.2.
