WARNING: 

To prevent the risk of fire or electric shock, never expose this volume control to 

rain or humidity.

SAFETY PRECAUTIONS

1.   All the precautions, 

in particular the safety ones,

 must be read with special attention, 

as they 

provide important information.

2.  

Loudspeaker lines (from amplifier outputs) can have a sufficiently high voltage (i.e. 100 V) to 
involve  a  risk  of  electrocution: 

never install or connect this volume control when the line is 

alive.

3.  

Make sure all connections have been made correctly, verifying that the line voltage matches the 
volume control specifications.

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 volume control, as this may cause a short 
circuit.

6.  

Never attempt to carry out any operations, modifications or repairs.

 

Contact your authorized service centre or qualified personnel should any of the following occur:
The volume control does not function (or works in an anomalous way).
Objects or liquids have got into the volume control.
The volume control has been damaged (due to heavy impacts or fire).
