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.

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.
