SAFETY AND OPERATING

PRECAUTIONS

IMPORTANT NOTES

Before connecting and using this product, please read this instruction manual
carefully and keep it on hand for future reference. This manual is to be
considered an integral part of this product and must accompany it when it
changes ownership as a reference for correct installation and use as well as
for the safety precautions.
RCF S.p.A. will not assume any responsibility for the incorrect installation and
/ or use of this product.

SAFETY AND OPERATING PRECAUTIONS

1. All the precautions, in particular the safety ones, must be read with special

attention, as they provide important information.

2. Loudspeaker lines (amplifier outputs) can have a sufficiently high voltage
(i.e. 100-70 V) to involve a risk of electrocution: never install or connect this
loudspeaker when the line is alive.

3. Make sure all connections have been made correctly and the loudspeaker
input voltage is suitable for the amplifier output.

4. Protect loudspeaker lines from damage. Make sure they are positioned in a
way that they cannot be stepped on or crushed by objects.

5. Make sure that no objects or liquids can get into this product, as this may
cause a short circuit.

6. Never attempt to carry out any operations, modifications or repairs that
are not expressly described in this manual.
Contact your authorized service centre or qualified personnel should any of
the following occur:

- The loudspeaker does not function (or works in an anomalous way).

- The cable has been damaged.

- Objects or liquids have got into the unit.

- The loudspeaker has been damaged due to heavy impacts or fire.

IMPORTANT NOTES

7. Should the loudspeaker emit any strange odours or smoke, remove it from

the line after having immediately switched the amplifier off.

8. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do
not try to hang this loudspeaker by using elements that are unsuitable or not
specific for this purpose.
Also check the suitability of the support surface to which the product
is anchored (wall, ceiling, structure, etc.) and the components used for
attachment (screw anchors, screws, brackets not supplied by RCF etc.),
which must guarantee the security of the system / installation over time, also
considering, for example, the mechanical vibrations normally generated by
transducers.

9. RCF S.p.A. strongly recommends this product is only installed by
professional qualified installers (or specialised firms) who can ensure a
correct installation and certify it according to the regulations in force.
The entire audio system must comply with the current standards and
regulations regarding electrical systems.

10. Mechanical and electrical factors need to be considered when installing
a professional audio system (in addition to those which are strictly acoustic,
such as sound pressure, angles of coverage, frequency response, etc.).

11. 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.
See the technical specifications in the instruction manual for the maximum
sound pressure the loudspeaker is capable of producing.

12. To ensure a correct sound reproduction, loudspeaker phase is to be
respected (loudspeakers are connected respecting the amplifier polarity).
This is important when loudspeakers are installed adjacent one another, for
instance, in the same room.

13. To prevent inductive effects from causing hum, noise and a bad system
working, loudspeaker lines should not be laid together with other electric
cables (mains), microphone or line level signal cables connected to amplifier
inputs.

14. The loudspeaker cable shall have wires with a suitable section (twisted,
if possible, to reduce inductive effects due to surrounding electro-magnetic
fields) and a sufficient electrical insulation. Refer to local regulations since
there may be additional requirements about cable characteristics.

15. Install this loudspeaker far from any heat source.

16. Do not use solvents, alcohol, benzene or other volatile substances for

cleaning the external parts of this product. Use a dry cloth.
