WARNING
When the Unit is in Use
Should the following irregularity be found•
during use, immediately switch off the
power, disconnect the power supply plug
from the AC outlet and contact your nearest
Quest dealer. Make no further attempt to
operate the unit in this condition as this
may cause fire or electric shock.
If you detect smoke or a strange smell•
coming from the unit.
If water or any metallic object gets into•
the unit
If the unit falls, or the unit case breaks•
If the power supply cord is damaged•
(exposure of the core, disconnection, etc.)
If it is malfunctioning (no tone sounds.)•
To prevent a fire or electric shock, never•
open nor remove the unit case as there are
high voltage components inside the unit.
Refer all servicing to your nearest Quest
dealer.
Do not place cups, bowls, or other•
containers of liquid or metallic objects on
top of the unit. If they accidentally spill into
the unit, this may cause a fire or electric
shock.
Do not insert nor drop metallic objects or•
flammable materials in the ventilation slots
of the unit’s cover, as this may result in fire
or electric shock.
When Installing the Unit
Do not expose the unit to rain or an•
environment where it may be splashed by
water or other liquids, as doing so may
result in fire or electric shock.
Use the unit only with the voltage•
specified on the unit. Using a voltage
higher than that which is specified may
result in fire or electric shock.
Do not cut, kink, otherwise damage nor•
modify the power supply cord. In addition,
avoid using the power cord in close
proximity to heaters, and never place
heavy objects -- including the unit itself --
on the power cord, as doing so may result
in fire or electric shock.
Be sure to replace the unit’s terminal cover•
after connection completion. Because
high voltage is applied to the speaker
terminals, never touch these terminals to
avoid electric shock.
Be sure to ground to the earth terminal to•
avoid electric shock.

CAUTION
An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be
incorporated in the electrical installation of the building.
When Installing the Unit
Never plug in nor remove the power•
supply plug with wet hands, as doing so
may cause electric shock.
When unplugging the power supply cord,•
be sure to grasp the power supply plug;
never pull on the cord itself. Operating the
unit with a damaged power supply cord
may cause a fire or electric shock.
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.
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 direct
sunlight, near heaters, or in locations
generating sooty smoke or steam as doing
otherwise may result in fire or electric
shock.
When the Unit is in Use
Do not place heavy objects on the unit•
as this may cause it to fall or break which
may result in personal injury and/or
property damage. In addition, the object
itself may fall off and cause injury and/or
damage.
Contact your Quest dealer as to 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.
