CCD Camera Operating Manual for the Model ST-4X, ST-5 and ST-6 Santa Barbara Instrument Group 1482 East Valley Road Santa Barbara, CA 93108 Phn (805) 969-1851 Fax (805) 969-4069 Note: This equipment has been tested and found to comply with the limits for a Class B digital device pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the receiver and the equipment. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Also note that user must use shielded interface cables in order to maintain product within FCC compliance. CCDOPS Manual Revision 2A January 1996 Table of Contents 1.
