are some other important safety instructions and
precautions you should follow:
• Read and understand all instructions before
installing, operating, or maintaining this
equipment.
• Do not connect this unit to the system when

sounds, which may cause, in certain situations,
permanent hearing loss. The device should be
installed far enough away from potential listeners
to limit their exposure while still maintaining
its effectiveness. The OSHA Code of Federal
Regulations 1910.95 Noise Standard provides
guidelines for permissible noise exposure levels.

screws are tightened.
• Establish a procedure to routinely check
the signal system for proper activation and
operation.
