PRECAUTIONS
Place the system near a power outlet so you can
easily plug it in.
Connect the included power cord only to an AC
outlet of the type stated in this manual or printed on
the system.
Hold the power cord plug when disconnecting it from
an AC outlet. Never pull the cord in case you
damage it.
Do not scratch, bend, twist, pull, or heat the power
cord. Do not place heavy objects, including this
unit, on top of the power cord. Be careful not to
place heavy objects on a power cord covered by a
carpet, either. A damaged power cord can easily
cause fire or electrical shock hazard.
If the power cord is damaged (i.e., cut or a bare wire
is exposed), ask the local dealer for a replacement.
Using the unit with a damaged power cord can easily
cause fire or electrical shock hazard.
Do not touch the power plug with wet hands. Doing
so may lead to potential electrical shock hazard.
Should this unit be dropped or the cabinet be
damaged, turn the power switch off immediately.
Then remove the power plug from the AC outlet, and
contact the local dealer. If you ignore it and
continue to use the unit without following this
instruction, fire or electrical shock is a very likely
result.
If you smell anything, or notice any abnormality,
such as smoke, odor, or noise, or if a foreign object
or liquid gets inside the unit, turn it off immediately .
Remove the power cord from the ACoutlet. Consult
your dealer for repair. Using the unit in this
condition could easily cause fire or electrical shock
hazard.
Turn off all audio equipment and speakers when
connecting to this unit. Use the correct connecting
cables and connect as specified.
Always lower the volume control to the minimum
level before turning power on. A sudden blast of
sound may cause hearing discomfort.
When rack-mounting the unit, allow enough free
space around the unit for normal ventilation.
For normal ventilation during operation, remove the
rear of the rack or open a ventilation hole. If the
airflow is not adequate, the unit will heat up inside
and may cause fire.
If you stack the speakers, secure the handles of the
speakers by using a belt and fix the speakers to the
floor or wall to prevent them from falling and causing
injury. Without safety protection in advance, do not
stack more than two speakers.
Do not use the handles to suspend the speaker; it
may otherwise fall and cause injury .
XLR-type connectors are wired as follows:
pin 1=ground, pin 2=hot(+), and pin 3=cold(-).
Using a mobile telephone near this unit may induce
noise. If noise occurs, take the telephone away from
the unit.
Do not use the speaker at uncomfortably loud level
that may cause hearing discomfort.
Do not allow water to spill into this system or allow
the unit to become wet, which may result in
electrical shock.
Do not place a container with liquid or small metal
objects on top of this system. Liquid or metal
objects inside this system are could easily cause
fire or electrical shock hazard.
Do not remove the unit
’
s cover. You would likely
receive an electrical shock. If internal inspection,
maintenance, or repair is necessary, please refer to
your dealer.
Do not modify the unit under any circumstance.
Doing so can easily cause fire or electrical shock
hazard.
