DO NOT CONNECT THE PLUS TO A PRO HUB OR OCTO HUB. Damage to either system can occur!
English
Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably to noise induced hearing loss but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time.
The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures:
| DURATION PER DAY (HOURS) | 8 | 6 | 4 | 3 | 2 | 1 |
| SOUND LEVEL (dB) | 90 | 93 | 95 | 97 | 100 | 103 |
According to OSHA, any exposure in the above permissible limits could result in some hearing loss. Ear plugs or protectors in the ear canal or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss. If exposure in excess of the limits as put forth above, to insure against potentially harmful 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.
