permanent hearing loss. Individuals vary considerably to sound 
pressure level induced hearing loss but nearly everyone will 
lose some hearing if exposed to high sound pressure levels 
for a sufficient amount of time. Therefore it is recommended 
that all persons exposed to equipment capable of producing 
high sound pressure levels, such as this device, be protected by 
hearing protection while installing or operating this unit. 

•  Read all documentation before operating your equipment.

•  Keep all documentation for future reference.

•  Save the carton and packing material even if the equipment has 

arrived in good condition. 

•  Should you ever need to ship the unit, use only the original 

factory packing.

•  Do not spill water or other liquids into or on the unit.

•  Make sure power outlets are conform to the power 

requirements listed on the back of the unit. 

•  Do not use the unit if the electrical power cord is frayed or 

broken. 

•  Always operate the unit with the AC ground wire connected to 

the electrical system ground.
