IMPORTANT SAFETY AND INSTALLATION INSTRUCTIONS
WARNING: Do not remove the product’s covers. This product contains no user serviceable parts.
WARNING: To reduce the risk of electric shock or fire, do not expose this product to rain or moisture.
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of an 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.
SAFETY INSTRUCTIONS
WARNING: To prevent the risk of electric shock please carefully read and follow the instructions below.
1. Before attempting to use this product please read all of the safety and installation instructions and the
explanation of safety symbols in this manual
2. This product must be grounded. This reduces the risk of electric shock in the event of a malfunction.
This product is supplied with a power supply cable that incorporates a conductor to connect the equipment
to ground and a power plug that incorporates a grounding pin. The plug must be connected to a power
outlet that incorporates a ground connection and which has been properly installed and grounded in
accordance with all the appropriate regulations. If the power cable or plug shows any signs of damage,
please consult a qualified service technician.
DANGER: Incorrect connection of the equipment’s grounding can result in a serious risk of electric shock.
Under no circumstances should the cable or plug provided with this product be modified. If it will not fit in
the power outlet, contact your supplier for a power cable fitted with the appropriate plug, or have an
appropriate outlet installed by a qualified electrician.
NEVER use an adaptor that defeats the ground connection. This can have potentially fatal consequences.
If you have any doubt as to whether your product is properly grounded, please consult a qualified
electrician.
3. The product is designed solely for operation indoors in audio and video systems in domestic
environments.
4. Do not use this product in an environment that is damp or has a high relative humidity, or that is near
water, such as close to a bath tub, wash basin, kitchen sink, in a damp basement, or near a swimming pool
or other similar environment. Moisture can bypass the electrical insulation and pose a risk of lethal electric
shock.
5. This product in combination with loudspeakers may be capable of producing sound levels that could
cause permanent hearing loss. Do not operate at a high-volume level, or at a level that is uncomfortable.
If you experience any hearing loss or ringing in the ears, you should consult an audiologist.

6. Do not block the ventilation slots on the top and bottom of the product. If you are positioning the product
on top of a carpet, ensure that the carpet pile does not obstruct the ventilation slots on the bottom of the
product. If you are placing the product on a soft surface which will come closer to the underside of the unit
than the height of the feet, place a suitable flat, hard base under the product.
If you are placing the product in a cabinet, ensure that there is adequate ventilation.
7. Do not position the product near naked flames, or other sources of heat such as radiators, heaters or
ovens.
Note that electric equipment, including some amplifiers, may heat up significantly during operation.
8. The product should only be connected to a power supply of the type shown on the product’s rear panel
by the power inlet.
9. If the product is to be left unused for a prolonged period of time, the power supply cable should be
removed from the outlet.
10. Always remove cables by holding the connector. Never pull or twist the cable itself.
11. When connecting cables always ensure that the connectors are of the appropriate type and are
properly aligned. Never use excessive force when inserting a plug into a socket. If a plug will not easily fit
into the socket, find out why.
12. Arrange the power cable in such a way that there is no risk of it being damaged e.g. by being stepped
on, by having anything placed on top of it, by someone tripping over it, having anything rolled over it, being
abraded by sharp edges or by being bent in an excessively tight radius. Failure to observe these
precautions may create the possibility of a fire risk and/or personal injury.
13. If the product is to be placed on a rack, stand or other supporting device, ensure that it is capable of
safely supporting the weight of the product.
14. Do not allow any liquids, or foreign objects to enter the product. If this happens, immediately switch
the product off and disconnect it from the power outlet, then contact qualified service personnel for
assistance.
15. Always unplug the unit from the wall outlet before cleaning. All that is required is a wipe with a dry
cloth or duster. Never use paint thinners or any other kind of solvent to clean this product. These constitute
a fire hazard and may also damage certain plastics.
16. If you notice an abnormal smell, or smoke coming from the product, immediately switch the product
off and disconnect it from the power outlet, then contact qualified service personnel for assistance.
17. In the event of any of the following occurring, you should seek the assistance of qualified service
personnel.
a. There is damage to the power supply cable or plug.
b. The product has been exposed to rain.
