IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS – Carefully and become familiar with the features
and functions of these products before operating them.
RETAIN THESE INSTRUCTIONS – For future reference.
COMPLY WITH ALL WARNINGS – Non compliance may void warranty of the
product.
USE WITH AMPLIFIERS – In order to avoid damage to drivers and other
equipment, it is advisable to establish and follow a routine for powering up
and powering down a sound system. With all system components
connected, turn on source equipment (mixers, signal processors, record
and playback units etc.) BEFORE powering up amplifiers. Transient voltages
from powering up source equipment can damage speakers if amplifiers are
already turned on. Make sure that amplifier volumes are set to their
minimum settings and power up any system amplifiers LAST. It is
recommended that all system components be allowed to stabilize for few
seconds before any source signals are introduced or level setting
adjustments are made. Similarly, when shutting systems down, turn all
amplifiers off first, before powering down any other system components.
CABLES – Do not use shielded or microphone cables for connection
between amplifiers and speakers. Use only approved speaker cables with
proper connectors.
RIGGING – SUSPENDING – MOUNTING – RIGGING – Suspending and
mounting of these speaker systems can expose members of the public to
serious health risks and even death. Under no circumstances attempt to rig,
suspend or otherwise mount these speakers unless you are fully qualified
and certified to do so by relevant local, state and national authorities. All
relevant safety regulations must be followed. If you are not properly
qualified or do not know of pertinent regulations, consult qualified
personnel for advice.
CAUTION – These professional loudspeaker systems are capable of
generating very high sound pressure levels. Use care with placement and
operation to avoid exposure to excessive volume levels. Permanent hearing
damage can result when operated to extreme levels.
SERVICE – There are no user serviceable parts inside this product. Users
should not attempt to service this product. Warranty nullification could
result if this is attempted.
