7. CARE MAINTENANCE Your Control Contractor system has been designed and manufactured for durability and reliable service As with any fine product proper maintenance and care will extend the life of your system You can expect your system components to perform indefinitely if you use them within their stated limits for power handling and see that they are not abused Always protect the loudspeakers from over excursion caused by strong subsonic signals signals below 30Hz If your amplifier has a low cut or high pass switch engage it Please note that although the C23 C25 and C28 are designed to be weather resistant they are NOT WEATHERPROOF Insect screens have been included in the design of the low frequency vents It may be wise to periodically check and clear any debris collected to ensure proper operation of the vent It is not unheard of for rodents to eat and destroy foam It is recommended that the foam surrounding the SB 2 subwoofer enclosure be treated with a rodent repellent especially in an installation that may be subject to the occasional rodent visitation JBL LIMITED WARRANTY Contro Contractor products are designed and backed by JBL the world leader in sound reinforcement For complete JBL warranty information within the United States please refer to the warranty card enclosed with your Control Contractor product In other areas of the world please contact your local JBL distributor Action Re
