Daktronics identifies manuals by their engineering document (ED) number, which is
located on the cover page of the manual. For example, this manual would be referred
to as ED-16084.
The serial and model numbers of a Daktronics display can be found on the ID label
on the display. The label will be similar to the one shown in Figure 2. When calling
Daktronics Customer Service, please have this information available to ensure that
your request is serviced as quickly as possible. For future reference, note your
display model number, serial number, and installation date on the front page of this
manual.
Daktronics displays are built for long life and require little maintenance. However,
from time to time, certain display components will have to be replaced. The
Replacement Parts List in Section 4 provides the names and part numbers of
components that may require replacement during the life of this display.
Following the Replacement Parts List is an explanation of Daktronics exchange and
replacement programs. Refer to these instructions if you must replace or repair any
display component.
