Liquid or particles must never be allowed to get inside the unit through
the ventilation slots. Mains voltage is present inside the unit, and any
electric shock could cause serious injury or death. Never exert undue
force on mains connectors.
Protect the unit from drips and splashes of water; never place flower
vases or fluid containers on the unit.
Do not place naked flame sources, such as candle lights on the
device.
Like any other electrical appliance this device should never be used
without proper supervision. Take care to keep the unit out of the reach
of small children.
The case should only be opened by a qualified specialist technician.
Repairs and fuse replacements should be entrusted to an authorised
 specialist workshop. With the exception of the connections and
measures described in these instructions, no work of any kind may be
carried out on the device by unqualified persons.
If the unit is damaged, or if you suspect that it is not functioning
correctly, immediately disconnect the mains plug at the wall socket,
and ask an authorised  specialist workshop to check it.
The device is designed to operate in a temperate climate and altitudes
up to 2000 m above sea level. The range of permissible operating
temperatures is +10 ... +35°C.
This device is designed exclusively for reproducing sound and/or
pictures in the domestic environment. It is to be used in a dry indoor
room which meets all the recommendations stated in these
instructions.
Where the equipment is to be used for other purposes, especially in
the medical field or any field in which safety is an issue, it is essential
to establish the unit's suitability for this purpose with the manufacturer,
and to obtain prior written approval for this usage.
The unit may be damaged by excess voltage in the power supply, the
mains circuit or in aerial systems, as may occur during thunderstorms
(lightning strikes) or due to static discharges.
Special power supply units and excess voltage protectors such as the
 'Power Bar' mains distribution panel offer some degree of
protection from damage to equipment due to the hazards described
above.
However, if you require absolute security from damage due to excess
voltage, the only solution is to disconnect the unit from the mains
power supply and any aerial systems.
To avoid the risk of damage by overvoltages we recommend to
disconnect all cables from this device and your HiFi system during
thunderstorms.
All mains power supply and aerial systems to which the unit is
connected must meet all applicable safety regulations and must be
installed by an approved electrical installer.
