 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  

  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  

 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.
