GENERAL CARE
The grille is held in place by pins near the edges. To remove the grille, grasp it by both top and bottom edges and pull gently. To replace grille,
NOTE: The J50 grille is non- removable. Do not attempt to pry the grille from the cabinet as this will void your warranty. The rear panels are removable to allow ser- vice personnel access to the driver components if needed.
The loudspeaker cabinet may be cleaned with a slightly damp cloth. To remove dust from the grille cloth, use a vacuum with a brush attachment. Spots may be removed with a com- mercial spot remover. Do not use any cleaners or solvents on the speaker drivers themselves.
SERVICE
Should your loudspeaker ever need service, return it to the JBL dealer from whom it was purchased. If pur- chased outside the United States, contact your local distributor to make arrangements for repair service. Do not return products to the JBL fac- tory without prior authorization.
