• When moving the unit, be sure to remove its power
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
cause damage to the power cord, resulting in fire or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
• To avoid electric shocks, be sure to switch off the
unit's power when connecting speakers.
• The unit is designed exclusively to be mounted in
an equipment rack. Be sure to follow the
instructions below when rack-mounting the unit.
Failure to do so may cause a fire or personal injury.
· Install the equipment rack on a stable, hard floor.
Fix it with anchor bolts or take other arrangements
to prevent it from falling down.
· Be sure to use the screws with a diameter of over
5 mm (0.2") and length of over 12 mm (0.47") to
mount the unit.
· When connecting the unit's power cord to an AC
outlet, use the AC outlet with current capacity
allowable to the unit.
When the Unit is in Use
• With the High-pass filter jumper socket kept to the
OFF position (factory preset), operating the unit for
long periods of time while the Peak indicator is
illuminated due to excessive input signal may
damage the connected speakers, possibly resulting
in fire. Operating the unit with the High-pass filter
jumper socket set to the ON position may decrease
the possibility of speaker damage or fire due to
excessive input signal.
• Make sure that all volume controls are set to
minimum position before power is switched on.
Loud noise produced at high volume when power is
switched on can impair hearing.
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
• Contact your TOA dealer as to the cleaning. If dust
is allowed to accumulate in the unit over a long
period of time, a fire or damage to the unit may
result.
• If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
• Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.
An all-pole mains switch with a contact
separation of at least 3 mm (0.12") in each pole
shall be incorporated in the electrical installation
of the building.
The lighting flash with 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.
