 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  first  and
 understand the safety symbols and messages so you are thoroughly aware of the potential safety 

Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.

Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.

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  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  off  the  power, disconnect
   the  power  supply   plug  from  the  AC  outlet  and 
   contact  your  nearest  sound choice 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 sound choice 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.
