SECURITY AND THE ENVIRONMENT

ELECTRICAL SECURITY
Check that the current in the mains connection where the machine is to be installed corresponds to the
power supply of the machine.
To avoid damaging the equipment, electrical shocks, fire or physical injury when you connect or disconnect
the equipment from the power supply, pull the plug firmly out of the mains socket holding the plug, never the

cable.
Always do this with dry hands.
Keep the power supply cable far from sources of heat. Do not put heavy objects on top of it or change it.
Clean dust and dirt off the power supply cable regularly.
Do not open the machine; you could get an electric shock.

CAUTION
While installing the machine, make sure it is switched off and unplugged.
Do not open the machine. Touching the internal parts is dangerous and you could receive an electric shock.
The machine must not be splashed or dripped on. Never place recipients with liquid inside on the machine.
Do not place anything inside the machine.

LOCATION
Place the equipment on a horizontal surface with enough space around it to allow ventilation.
Avoid direct sunlight, heat sources and excessive dust.

Do not place the machine near magnetic fields or static electricity.
Do not use surfaces which vibrate or receive impact.
Do not pile machines on top of one another.

VENTILATION
Never block or cover the ventilation slits on the machine.
Do not expose it to direct sunlight or place it near sources of heat.

PERIODS OF INACTIVITY
When the machine is not going to be used for a long period of time, disconnect it from the mains.
If you are using an adapter, take into account that it will continue using electricity even if the machine is
switched off. If it is not going to be used for a long period of time, disconnect it from the mains.

THE ENVIRONMENT
To save energy, switch the machine off when you are not going to use it for a long time. The machine could
contain substances that are harmful to the environment or human health. To minimize the effect of these
substances the machine must be correctly managed and recycled when you decide to dispose of it.
When you dispose of it remember: it cannot be thrown into a conventional rubbish bin.
If it contains or uses batteries, these must be disposed of separately.
The machine (without batteries) must be disposed of correctly. Put it in a container specially intended for the
collection of electronic and electrical appliances, at the dump or hand it over to the dealer when you purchase

similar equipment, so that the dealer can dispose of it correctly (at no added cost).

SIGNIFICANCE OF THE SYMBOLS ON THE MACHINE*

The symbol formed by the expression “Class 1 laser product” written in a rectangle
indicates that visible or invisible laser radiation could be produced. Avoid direct exposure
to the laser.

The symbol formed by a ray of lightening inside a triangle shows that the machine has
connection terminals or a circuit with areas with a current which could cause an electric
shock, even in normal working conditions.

The symbol formed by an exclamation mark in a triangle shows that the instruction manual
must be referred to for information on how the machine works and its use.

The symbol formed by one square inside another square shows that the machine has
double electrical insulation.

The European Community symbol shows that the machine complies with the current
European Union legislation, as well as its transposition to local legislation.

The symbol of a rubbish bin crossed out and over a horizontal line shows that when the
product is disposed of it must be done properly, placing it in a special selective electronic
and electrical equipment container or through a dealer when purchasing a similar product,
at no additional cost. It also shows that the machine was put on the market after 13th
August 2005 (European Community Directive 2002/96/CE of Electrical and Electronic
recycling, and its Spanish equivalent R.D.208/2005).
