9. Unplug the amplifier during lightning storms or when unused for long periods of time. 10. Refer all servicing to qualified service personnel. Servicing is required when the amplifier has been damaged in any way. Some examples-when the power cord or plug is damaged, liquid has been spilled, objects have fallen into the amplifier, the amplifier has been exposed to rain or moisture, it does not operate normally, or has been dropped. 11. Never break off the ground pin and connect only to a proper power supply type, indicated on the unit. For more information, write for our free booklet "Shock Hazard and grounding". 12. If this product is to be mounted on an equipment rack, rear support should be provided. 13. Exposure to extreme high noise levels may cause permanent hearing loss. Individuals vary considerably in regards to noise-induced hearing loss, but nearly everyone will experience some damage if exposed to intense noise for an extended period of time. The US Government's Occupational and Health Administration (OSHA) has specified the following permissible noise level exposures: SOUND LEVEL dBA, SLOW RESPONSE 8 6 4 3 2 1 1/2 1 1/2 1/4 OR LESS DURATION PER DAY IN HOURS 90 92 95 97 100 102 105 110 115 According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors to the ear canals must be worn when operating this amplification system, in order to prevent permanent hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hearing protectors while this unit is in operation. 2
