IMPORTANT NOTES

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. 

Speaker 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 
speaker when the line is alive.

3. 

Make sure all connections have been made correctly and the speaker input 

voltage is suitable for the amplifier output.

4.

 Protect speaker 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 speaker does not function (or works in an anomalous way).

 

-

The cable has been damaged.

 

-

Objects or liquids have got into the unit.

 

-

The speaker has been damaged due to heavy impacts or fire.

7. 

Should the speaker emit any strange smell 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 speaker 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 (wall plugs, 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.
