Fusionbrands Fusionbrands, Inc. Home Theater System MS-FR402 ユーザーズマニュアル

Before you contact your FUSION dealer or service centre, FUSION requires that you do some 

simple trouble shooting to help diagnose the problem.
If the FUSION speaker has been installed by a professional installation company, then we 

recommend that you return to the company so the technician can assess the problem and 

advise.

FUSION Marine Speakers (with the exception of MS-FR402) feature a variety of grille op-

tions, allowing you to customise your speakers to match or enhance the appearance of 

your craft. Each pair of MS-FR602 and MS-FR702 speakers include a choice of three differ-

ent grilles and three different gel badges.

NOTE: MS-FR402 only feature the standard grille option, but still offer all three gel badge 

options.

The standard grilles are factory-fitted to the speakers, and are 

the most rugged and offer the highest level of protection. FUSION 

recommends using the standard grilles in high traffic areas, or 

where objects are liable to be moving around or knocking into the 

speakers.

The cloth grilles are designed to enhance the internal cabin area. 

The cloth insert is removable, via the screws on the inside of the 

grille - allowing you to change the cloth to compliment the cabins 

decor. 

The sport grilles provide a third grille alternative for your speakers.
