FCC/DOC Compliance 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 when the equipment is operated in a residential installation. This equipment generates, uses, and can radiate radio frequency energy. If the equipment is not installed and used in accordance with the instructions, it 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, try to correct the interference as follows: reorient or relocate the affected device; increase the separation between this equipment and the affected device; connect this equipment to an outlet on a circuit different from the circuit to which the affected device is connected; consult a dealer or an experienced radio/television technician for help. For additional regulatory information, see the label attached to the back of the equipment. This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la classe B respecte toutes les exigencies du Règlement sur le materiél brouilleur du Canada. Safety Notices Service and upgrade tasks should be performed by users who can follow instructions in a manual to service equipment, and can do so without harm to themselves or damage to the equipment. To reduce the risk of electrical shock and energy hazards, do not attempt to open the equipment unless instructed, and do not use a tool for purposes other than instructed. Internal components may be at high temperatures. Allow time for them to cool before handling them. Internal components can be damaged by static electricity. Use an antistatic wrist strap connected to the bare metal of the system’s chassis to protect against electrostatic discharge. Notes Changes or modifications made to the system that are not approved by the party responsible for compliance could void the user's authority to operate the equipment. Procedures in this document assume familiarity with the general terminology associated with personal computers, and with the safety practices and regulatory compliance required for using and modifying electronic equipment. Read all operating instructions before using this device. Keep these instructions for future reference. Follow all warnings on the device or in the operating instructions.
