Duration per day in hours Sound Level dBA, slow response
8 90

limits could result in some hearing loss.
• Ear plug 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 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.
• Fuses: Replace with IEC 127 (5 x 20 mms) type and rated fuse for best
