Operating Precautions; Introduction - RCF PL60 Instructions D'installation Et D'emploi

Hearing loss - Exposure to high sound
levels can cause permanent hearing loss.
The sound pressure level which leads to
hearing loss varies considerably from one person to
another, and depends on the duration of exposure.
The U.S. Government's Occupational Safety and Healt
Administration (OSHA) has established the maximum
sound pressure levels that can be withstood without
causing damage, which are shown in the table below.

Consult the specifications provided in the
instruction manual to know the maximum
sound pressure (SPL) the speaker is
capable of producing.

According to the OSHA regulations, any exposure
over the maximum limits indicated in the table can
reduce the hearing capacity of a person. To prevent
potentially dangerous exposure to high sound pres-
sure levels, anyone subjected to such levels must use
suitable protection. When an product capable of pro-
ducing high sound levels is being used, it is therefore
necessary to wear ear plugs or protective earphones
when the limits shown in the table are exceeded.

2. Operating precautions

• Do not use solvent, alcohol, benzene, or other vola-
tile substances for cleaning the external parts of the
speaker.
• Do not use the speaker in tropical climates.
• If the speaker is used in particulary could places,
drive it with a low signal for 5-10 minutes before
using it at maximum power.

design that can be flush-mounted in false ceilings or
panels. It can also be attached to walls or ceilings
using a special accessory for surface mount installa-
tion. The PL 60 incorporates a 160 mm (6") dual cone
loudspeaker that improves high frequency extension,
and it is equipped with a line transformer that ena-
bles direct connection to constant voltage systems at
70 V or 100 V. The multiple sockets on the transfor-
mer make it possible to select the output power from
among several values. Installation is quick and easy
thanks to a special three-terminal system that avoids
the need for using screws or other attachment ele-
ments.
