10. REPAINTING THE SPEAKER FRONT GRILLE

Note: Be sure to detach the front grille from the speaker before repainting.

Step 1. Clean the front grille before painting.

Wipe with a soft cloth dampened in a detergent.

Caution

Do not use thinner or other volatile liquids to clean the grille.

Step 2. Spray on a uniform, thin coat of paint.

Cautions

• Avoid painting with a roller or brush, as the grille mesh holes could become clogged with paint.

• Use appropriate spray paints for the front grille (grille and frame) materials.

Grille: Rolled steel plate

Frame: Fire-resistant ABS resin (acrylic paint)

• Be sure to follow the directions indicated on the paint when painting.

Step 3. After the paint has dried, apply another light coat.

Caution

Repeating Step 2, apply two or more light coats of paint.

Application of one thick coat of paint all at once may cause drips or unevenness to show up in the

painted finish, or clog the mesh holes.

Both the F-2322CU2 and the F-2352CU2 feature internal input overload protection circuitry. If an extremely

high input level is fed to the unit, the protection circuitry automatically cuts off the signal to the speaker

element.

A drastic reduction in sound volume indicates that the protection circuitry has been enabled.

In such cases, simply reduce the amplifier volume. The protection circuitry will automatically reset in

approximately 10 seconds. After reset, try to maintain the volume at a level slightly lower than before.

Caution

This protection circuitry does not completely protect the unit against extremely high input power levels.

Depending on the type or duration of excessive power input, the protection circuitry might not be enabled,

resulting in damage to the speaker element. Also, if the excessive power input continues for a long period of

time, the circuitry may not be capable of resetting to its original condition.

Use the system with care so that the speakers are not exposed to excessive power input.
