IMPORTANT ! SAFETy INSTRUCTIONS
In order to protect your own and others' safety and to avoid inva-
lidating this product's warranty, please read this section carefully
before operating this product.
- This product has been designed and manufactured to be operated as a
speaker system in the typical applications of a sound reinforcement system
or of a sound recording system. Operation for purposes other than these is
not provided for by the manufacturer and is therefore to be undertaken at
the end user's and/or installer's sole risk and responsability.
TO AVOID THE RISK OF DAMAGE:
• Never expose this product to rain or moisture, never use it in proximity of
water or in high humidity conditions. Never let any liquid, as well as
any object, penetrate the product. Should this be the case, do not use the
speaker system and refer to qualified servicing before operating it again.
• This product must be connected only to the output of a power amplifier
or a powered mixer. Always use a good quality speaker cable (unscreened),
and check it frequently for any damage to insulation and connectors.
• When setting up the speakers, make sure that the connecting cables do
not create any obstruction or danger. As a general rule, never lay them
down in any area that may be accessed by the audience or by unqualified
personnel. If they are laid on the floor in an accessible area, secure them
to the floor using adhesive tape ("gaffa" tape) or insert them in a suitable
cable channel.
Make sure that in no case the speaker system can fall down because
someone has pushed or stumbled over a speaker cable.
It is recommended to set up the speaker system using suitable accessories
(wall mounting brackets, speaker stands, etc.) according to the
manufacturer's installed hardware. If the speaker is simply placed on a
support, make sure that no harm or damage to people or to goods may be
caused by the speaker falling to ground.
When two loudspeakers are laid one upon the other, make sure that
stability is guaranteed by matching the upper loudspeaker feet to the
lower loudspeaker cavities.
If children and/or animals may have access to the installation site, a close
supervision is required.
• Before moving the product after it has been installed, or while it is
operating, make sure that the power amplifier is switched off.
• To disconnect this product from connecting cable never pull the cable
directly: hold it by the plug instead.
This product does not contain user serviceable parts.
To prevent damage never open it. For maintenance and repairs
always refer to the official Montarbo Distributor in your State or
to qualified personnel specifically authorised by the Distributor.
- This product can generate very high acoustic pressures which are
dangerous for the hearing system. Always avoid operation at loud levels
if anyone is excessively near (less than 1m distance) to the product.
☛ Never expose children to high sound sources.
