Safety guidelines

Important safety instructions

These products are designed and manufactured to meet 
strict quality and safety standards. However, you should 
be aware of the following installation and operation 
precautions:

1.  Take heed of warnings and instructions

You should read all the safety and operating instructions 
before operating these products. Retain this handbook for 
future reference and adhere to all warnings in the handbook 
or on the product itself.

2.  Water and moisture

The presence of electricity near water can be dangerous. Do 
not use these appliances near water – next to a bathtub, 
washbowl, kitchen sink, in a wet basement or near a 
swimming pool, etc.

3.  Object or liquid entry

Take care that objects do not fall and liquids are not spilled 
into the enclosure of a unit through any openings. Liquid-
filled objects such as vases should not be placed on these 
products.

4.  Ventilation

Do not place these units on a bed, sofa, rug or similar 
soft surface, or in an enclosed bookcase or cabinet, since 
ventilation may be impeded. We recommend a minimum 
distance of 50mm (2 inches) around the sides and top of 
the each unit to provide adequate ventilation.

5.  Heat

Locate these products away from naked flames or heat 
producing equipment such as radiators, stoves or other 
appliances (including other amplifiers) that produce heat.

6.  Climate

These products have been designed for use in moderate 
climates.

7.  Racks and stands

Only use a rack or stand that is recommended for use with 
audio equipment. If the equipment is on a portable rack it 
should be moved with great care, to avoid overturning the 
combination.

8.  Cleaning

Unplug a unit from the mains power supply before cleaning.
The cases should normally only require a wipe with a soft, 
damp, lint-free cloth. Do not use paint thinners or other 
chemical solvents for cleaning.
We do not advise the use of furniture cleaning sprays or 
polishes as they can cause indelible white marks if the unit 
is subsequently wiped with a damp cloth.

9.  Power sources

Only connect an unit to a power supply of the type 
described in the operating instructions or as marked on the 
product itself.
The primary method of isolating these products from the 
mains supply is to remove the mains lead from the rear of 
the unit. These products must be installed in manner that 
makes this disconnection possible.
These are Class 1 devices and must be earthed.

10. Power-cord protection

Power-supply cords should be routed so that they are not 
likely to be walked on or pinched by items placed upon or 
against them. Pay particular attention to cords and plugs, 
and the point where they exit from the unit.

11. Grounding

Ensure that the grounding means of these products is not 
defeated.

12. Power lines

Locate any outdoor antenna/aerial away from power lines.

13. Non-use periods 

When using the stand-by function, a small amount of 
current will continue to flow into the unit. Unplug the power 
cord of a unit from the outlet if it is to be left unused for a 
long period of time.

14. Abnormal smell

If an abnormal smell or smoke is detected from a unit, turn 
the power off immediately and unplug the unit from the 
wall outlet. Contact your dealer for further advice.

15. Servicing

You should not attempt to service these products beyond 
that described in this handbook. All other servicing should 
be referred to qualified service personnel.

16. Damage requiring service

These products should be serviced by qualified service 
personnel when:

A.  the power-supply cord or the plug has been damaged, 

or

B.  objects have fallen, or liquid has spilled into the 

appliance, or

C.  the appliance has been exposed to rain, or
D.  the appliance does not appear to operate normally or 

exhibits a marked change in performance, or

E.  the appliance has been dropped or the enclosure 

damaged.

Safety compliance

These products have been designed to meet the IEC 60065 
international electrical safety standard.

RISQUE DE CHOC ELECTRIQUE

ATTENTION

CAUTION

RISK OF ELECTRIC

SHOCK DO NOT OPEN

CAUTION: To reduce the risk of electric shock, do not remove cover (or back). No user serviceable parts inside. Refer servicing 
to qualified service personnel.
WARNING: To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated 
‘dangerous voltage’ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance 
(servicing) instructions in the literature accompanying the product.

CAUTION: In Canada and the USA, to prevent electric shock, match the wide blade of the plug to the wide slot in the socket 
and insert the plug fully into the socket.
