Grille Maintenance and Cleaning
To allow maximum acoustic transparency, the front of the cabinet contains a PVC mesh
grille. Do not apply anything to the surface that may obstruct the holes in the material. To
maintain the brightness of the colors and prolong the life of the grille, periodic cleaning is
necessary. Failure to clean periodically may result in permanent discoloration or staining.
When cleaning, use a mild soapy solution (Dove
®
, Ivory
®
, etc.) and a very soft brush,
moving in a circular motion. Rinse with clean water using normal faucet pressure.
Do not use a power washer�
Grille Mesh Replacement
Reference Drawings:
Mesh Layout; 2000HD Gen II ............................................................................. DWG-983337
If the grille mesh fades or tears over time, or if new graphics/logos are desired, it may be
replaced. Only qualified sign companies should be used to replace the grille mesh. Refer
to DWG-983337 for mesh layout. Contact Daktronics for mesh reordering.

The front of the sound cabinet has a removable aluminum frame that secures the
grille mesh ( Figure 14 ).

a total of twenty (20) 3/8" hardware sets, with ten (10) sets at both the top and

enough so that the weight is supported by the aluminum frame and not on the
mesh.
