4. HANDLING PRECAUTIONS
• It is recommended that the unit be always used in locations where the ambient temperature ranges from 0 to
+40 °C and humidity is less than 90% (no condensation).
• When cleaning the unit, be sure to disconnect the power supply plug from the AC outlet. Wipe with a soft dry
cloth. If it gets very dirty, use the soft cloth slightly moistened in neutral cleanser. Never use thinner,
benzene, chemically processed towels, or alcohol as the unit's plastic or other parts may be deformed or
discolored.
• When moving the unit, be sure to remove its power
supply cord from the AC outlet. Moving the unit
with the power supply cord connected to the outlet
may cause damage to the power supply cord,
resulting in fire or electric shock. When removing
the power cord, be sure to hold its plug to pull.
• Do not block the ventilation slots in the unit's cover.
Doing so may cause heat to build up inside the unit
and result in fire.
• 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.
• When unpacking or moving the unit, be sure to
handle it with two or more persons. Falling or
dropping the unit may cause personal injury and/or
property damage.
• To avoid electric shocks, be sure to disconnect the
power supply plug from the AC outlet when
connecting speakers.
• 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.
· 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
• Make sure that the volume control is 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. Doing so may cause
the connected speakers to heat, resulting 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.
• 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.
