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 the direct sunlight, near the 
  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.

    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 fire.

    Contact your 

 dealer as  to the  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.

Myers

  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.
