SAFETY PRECAUTIONS
A triangle with a lightning symbol draws the user's attention
to "dangerous voltage" without insulation in the cabinet
which may be high enough to entail a risk of electric shock.
A triangle with an exclamation mark draws the user's
attention to important instructions for use and maintenance
in the accompanying manual, which should be studied.
A symbol for CLASS II (double insulation)
WARNING:
CAUTION:
TO MINIMISE THE RISK OF FIRE OR ELECTRICAL SHOCK, DO NOT EXPOSE
THE UNIT TO RAIN OR MOISTURE. DO NOT OPEN THE CABINET AS IT
CONTAINS DANGEROUS VOLTAGE. ONLY QUALIFIED TECHNICIANS ARE
ALLOWED TO CARRY OUT REPAIR AND SERVICE.
If the plug of the power cord needs to be replaced, it is important that the replacement
is identical to the plug to be replaced, or that the new plug has been recommended by
the manufacturer
TO AVOID ELECTRICAL SHOCK, IT IS IMPORTANT TO INSERT THE PLUG
CORRECTLY INTO THE SOCKET.
03

Only the power supply indicated on the
rating plate must be used for this unit.
If you are not sure which power supply
you have, please contact the distributor
or the local electricity supplier.
Earthing or polarisation
If the plug cannot be inserted properly into the
socket, or if the plug does not fit, the unit must not
be used in your country.
Ventilation
The cabinet is provided with slots and
openings to ensure ventilation and reliable
operation and to protect the unit against
overheating. Do not block or cover these
openings. The openings must never be
blocked, for instance by placing the unit on
a bed, a sofa, a carpet or similar surface.
Heat

sources of heat such as radiators,
heat registers, ovens or other
units that produce heat.
Water and moisture
The unit must not be placed
close to water, such as bathtub,
wash basin, kitchen sink or
laundry tub, in a damp cellar or
close to a swimming pool, etc.
Cleaning
Unplug the unit before cleaning.
Do not use liquid detergents and
aerosol cleaning agents. Use a
dry cloth.
Power cords
Wiring must be organised to
prevent people from stepping on
the cables and to avoid pinching
by objects placed on or beside
them. Take special care around
sockets and plug boxes and
where the power cords leave the
unit.
Overloading

extension cords and plug
boxes are not overloaded as
this may lead to fire or
electrical shock.
04
IMPORTANT SAFETY INSTRUCTIONS
Lightning
Unplug the unit for additional
protection during thunder or when
the unit is not used for prolonged
periods. This will prevent damage
to the unit from lightning and
power surges.
Penetration of objects and liquid
Never push any foreign objects
through the openings into the unit,
as they may touch dangerous
voltage points or short-circuit parts
and thus cause fire or electric
shock. Do not spill liquid on the
unit.
Accessories
Do not place the unit on unstable surfaces such as a
trolley, stand, tripod, shelf or table. The unit
may fall and injure children or adults or
be seriously damaged. Use only trolley,
stand, tripod, shelf or table that is very
stable or provided with the unit. The unit
must be installed in accordance with the
manufacturer's instructions and by means of
installation equipment recommended by the
manufacturer.
If the unit is placed on a trolley, the trolley must be
moved very carefully. Sudden stops, unnecessary
force and uneven surfaces may cause the trolley to
turn over.
Damage

the following cases:
A) If the power cord or the plug is damaged.
B) If liquid has been spilled on the unit or objects
have fallen into the unit.
C) If the unit has been exposed to rain or water.
D) If the unit does not work properly after adhering to
the instructions in the operation manual. Only the
settings described in the operation manual must be
made as incorrect setting may result in damage and
often will make it difficult for a qualified technician to
make the unit work properly again.
E) If the unit has been dropped or damaged in any
other way.
F) When the operation of the unit changes
drastically, the unit requires service.
Service
Do not attempt to carry out any
service work yourself. By opening or
removing the cabinet, you will be
exposed to dangerous voltage or
other hazards. Any service work
should be carried out by qualified
technicians.
Spare parts
If spare parts are required, make sure that the
service technician uses spare parts specified by the
manufacturer or spare parts with the same
characteristics as the original. Unauthorised spare
parts may cause fire, electrical shock, etc.
Loads
Do not place heavy loads on the
unit and do not step on it. The load
may fall and cause serious injury to
persons or damage to the unit.
Safety check
After service or repairs on the unit,
ask the service technician to carry
out a safety check to ensure that
the unit is ready for use.

ADJUSTING THE ANTENNA
FM ANTENNA AM
Adjusting the antenna
As it applies to all other radios, the sound quality depends on the signal strength of the antenna inputs.
The position of the radio in relation to the transmitter thus directly influences the quality of the signal
received. For an optimal result it is therefore very important that you make sure that the radio receives the
best possible antenna signal.
The FM antenna must be adjusted for
the best possible result.
A good tip is to let the antenna end point
in a vertical direction and fix it on a wall.
For an optimal result it is recommended
to install a FM antenna on the roof or on
the loft.
For receiving AM station an AM loop
antenna must be installed. Adjust the
antenna for the best possible reception.

In some areas not all stations can be recieved
noise free, because it is not possible to get a
strong enough antenna signal.
In this case there will be a lot of noise on some
radio stations.
It is possible to reduce the noise quite a bit by
listening to the radio station in mono in stead of in
stereo. This can make the radio station acceptable
to listen to. Change to mono by pressing the
ST/MO button on the remote or the ST/MONO
button on the front panel. To change back to
stereo again, simply press the button once again.
