Cleaning -- Clean only with a dry cloth. 7. Ventilation -- This Mackie product should be situated so that its location or position does not interfere with its proper ventilation. For example, the Component should not be situated on a bed, sofa, rug, or similar surface that may block any ventilation openings, or placed in a built-in installation such as a bookcase or cabinet that may impede the flow of air through ventilation openings. 8. Heat -- This Mackie product should be situated away from heat sources such as radiators or other devices which produce heat. WARNING: The heatsink may reach high temperatures during standard use. To ensure proper operation, allow a minimum of 6 inches of clearance from the heatsink surface and adequate ventilation. 9. Power Sources -- This Mackie product should be connected to a power supply only of the type described in these operation instructions or as marked on this Mackie product. Pour prévenir les chocs électriques ne pas utiliser cette fiche polariseé avec un prolongateur, un prise de courant ou une autre sortie de courant, sauf si les lames peuvent être insérées à fond sans laisser aucune pariie à découvert. 15. Grounding or Polarization -- Precautions should be taken so that the grounding or polarization means of this Mackie product is not defeated. 16. Power Precaution -- Unplug this Mackie product during lightning storms or when unused for long periods of time. Note that this Mackie product is not completely disconnected from the AC mains service when the power switch is in the OFF position. 17. This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications. ATTENTION --Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant las limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le règlement sur le brouillage radioélectrique édicté par les ministere des communications du Canada. WARNING -- To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. WARNING -- The cabinet has no rigging points and is not suitable for flying. Never attempt to suspend the cabinet by its handles. The SA 1232 should never be pole-mounted. 2 Lend Me Your Ears Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noiseinduced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in this chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound-pressure levels, it is recommended that all persons exposed to equipment capable of producing these levels use hearing protectors while this unit is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here.
