5.1 Maintenance
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.
Note: Do not use a power washer.
Replacing the Grille Mesh
If the speaker 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 speaker mesh. Refer to
Drawing B-983304 for speaker mesh layout. Contact Daktronics for mesh reordering.
1. Removing Mesh Frame
The front of the sound cabinet has a removable aluminum frame that secures the
speaker mesh. This frame is attached to the sound cabinet with a total of eight (8)

hardware sets, with four (4) sets at both the top and bottom of the frame.
a. Carefully remove all mounting hardware and safely lower mesh frame to the
ground. Set the frame on a level surface large enough so that the weight is
supported by the aluminum frame and not on the mesh.
b. Loosen the screws on the radius cover using a square driver and remove.
2. Removing Tension Clips
Insert the tip of a standard
slotted screwdriver into the
recess located at the backside
of the tension clip (Figure 16).
Rotate or tilt the screwdriver to
separate the tension clip teeth
away from the frame. This will
allow the tension clip to be
removed from the frame by
prying or pulling it up and out.
Slide the mandrel out of the
tension clip to release the mesh.
