Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic
pressure level that leads to hearing loss is different from person to person and
depends on the duration of exposure.
To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is
necessary to wear ear plugs or protective earphones.
11.
To prevent inductive effects from causing hum, noise and a bad system
operating, paging microphone cables should not be laid together with other
electric cables (mains) and loudspeaker lines.
12.
Keep the paging microphone far from any excessive heat source.
13.
Do not use solvents, alcohol, benzene or other volatile substances for
cleaning the external parts. Just use a dry cloth.
