Daktronics displays are built for long life and to require little maintenance. However,
from time to time, certain display components will need to be replaced. The
Replacement Parts List in Section 4.5 provides the names and part numbers of
components that you may need to order during the life of this display. Most display
components have a white label that lists the part number. The component part
number is in the following format: 0P-____-____ (circuit board) or 0A-____-____
(multi-component assembly).
Following the Replacement Parts List is an explanation of the Daktronics
Exchange and Repair and Return Programs. Refer to these instructions if any
display component needs replacement or repair.
1.1 Safety Precautions
Important Safeguards:
1. Read and understand these instructions before installing the
display.
2. Be sure the display is properly grounded with a grounding
electrode at the display location.
3. Disconnect power to the display when it is not in use.
4. Disconnect power when servicing the display.
5. Do not modify the display structure or attach any panels or
coverings to the display without the written consent of Daktronics,
Inc.
1.2 Network Concepts
The concept of using LED technology displays as a cost effective, high impact
method of communication is rapidly growing throughout many industries and
businesses. The common thread of most requests is the available methods of
programming or controlling the displays.
Manual Control (Switch Inputs)
The Daktronics MF Series displays are controlled manually with a switch wired to
the display. A two-position switch configuration forces the display to show either of
the two message options. A three-position switch configuration forces the display to
show either of the two message options or the display can be turned off.
