Precautions
• Connect the power supply power cord only to an AC
outlet of the type stated in this
Owner’s Manual
or as
marked on the power supply unit. Failure to do so is a
fire and electrical shock hazard.
• Do not locate the power supply unit in a place subject
to excessive heat or in direct sunlight. This could be a
fire hazard.
• Do not place the power supply unit in a place subject
to excessive humidity or dust. This could be a fire and
electrical shock hazard.
• Do not plug several devices into the same AC outlet.
This may overload the AC outlet, and could be a fire
and electrical shock hazard. It may also affect the per-
formance of some equipment.
• Do not place heavy objects on the power cord. A dam-
aged power cord is a potential fire and electrical shock
hazard.
• If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the
power supply unit in this condition is a fire and shock
hazard.
• Hold the power cord plug when disconnecting from
an AC outlet. Never pull the cord. Damaging the
power cord in this way is a potential fire and electrical
shock hazard.
• Do not place small metal objects on top of the power
supply unit. Metal objects inside the power supply
unit are a fire and electrical shock hazard.
• Do not block the power supply unit ventilation slots.
The power supply unit has ventilation slots at the
front to prevent the internal temperature from rising.
Blocked ventilation slots are a fire hazard.
• Leave a reasonable amount of free-air space around
the power supply unit.
• If the power supply unit is to be rack mounted, leave
at least 10 cm free above the top panel and behind the
rear panel. When the power supply unit is in use,
remove the rear of the rack, or open its ventilation
slots to prevent overheating, which could be a fire
hazard.
• Do not try to modify the power supply unit. This
could be a fire and electrical shock hazard.
• The power supply unit operating temperature is
between 5˚C and 35˚C (41˚F and 95˚F).
• Turn off all audio devices and speakers when connect-
ing to the power supply unit. Refer to the owner’s
manual for each device. Use the correct cables and
connect as specified.
• If you notice any abnormality—such as smoke, odor,
or noise—turn off the power supply unit immediately.
Remove the power cord from the AC outlet. Confirm
that the abnormality is no longer present. Consult
your dealer for repair. Using the power supply unit in
this condition is a fire and shock hazard.
• If a foreign object or water gets inside the power sup-
ply unit, turn it off immediately. Remove the power
cord from the AC outlet. Consult your dealer for
repair. Using the power supply unit in this condition
is a fire and electrical shock hazard.
• If you plan not to use the power supply unit for a long
period of time, remove the power cord from the AC
outlet. Leaving the power supply unit connected is a
fire hazard.
• Do not use benzene, thinner, cleaning detergent, or a
chemical cloth to clean the power supply unit. Use
only a soft, dry cloth.
• The power supply unit uses high-frequency digital cir-
cuits that may cause interference on radios and televi-
sions placed close to it. If interference does occur,
relocate the affected equipment.
