Important Notes:
1. Disconnect power before performing any repairs or

maintenance work on the sign.

2. Only qualified service personnel may access internal sign

electronics.

3. The Daktronics engineering staff must approve ANY changes

made to the sign. Before altering the sign, you must submit to
the Daktronics engineering staff detailed drawings for the
proposed modifications for evaluation and approval or you

will void the warranty.
