SAFETY PRECAUTIONS
Be sure to read the instructions in this section carefully before use. Make sure to observe the instructions in this manual as the
conventions of safety symbols and messages regarded as very important precautions are included. We also recommend you
keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which
could result from mishandling. Before operating your product, read this manual rst and understand the safety symbols and
messages so you are thoroughly aware of the potential safety
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 re or electric shock.
Use the unit only with the voltage specied on the unit. Using a voltage higher than that which is
specied may result in re or electric shock.
Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proxim-
ity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in re 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 safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe as a catastrophic
disaster may result.
Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result
in the unit falling down, causing personal injury and/or property damage.
When the Unit is in Use
Should the following irregularity be found during use, immediately switch o the power, disconnect the power supply plug
from the AC outlet and contact your nearest dealer. Make no further attempt to operate the unit in this condition as this may
cause re 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.)

SAFETY PRECAUTIONS
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 re 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 re 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 re.
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 re 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 o and cause injury and/or damage.
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. This is an indication of a malfunction, which
in turn can cause heat to generate and result in a re.
Contact your dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of time, a re or damage
to the unit may result. HEINRICH If dust accumulates on the power supply plug or in the wall AC outlet, a re may result. Clean
it periodically. In addition, insert the plug in the wall outlet securely.
Switch o 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 re or electric shock.
