 SAFETY PRECAUTIONS

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.

     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.

     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  ontrol 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  ITC  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.

  If dust accumulates on the power supply plug or in
  the   wall  AC  outlet, a fire may result. Clean it peri-
  

odically. 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.

Due to product upgrades, while some of the 
features and specification in the user manual 
does not match the actual functions, sorry for
any inconvenience and  thanks for your kind 
understanding!
