CAUTION
 
Precaution
 
 
Never use this projector at an altitude of 3 000m or higher.
 
 
Using this projector at high altitude, consult your dealer or Authorized Service Center about preparations.
 
About lead free solder (PbF)
 
 
This projector is using the P.C.Board which applies lead free solder.
 
 
Use lead free solder in servicing from the standpoint of antipollution for the global environment.
 
Notes:
 
 
•  Lead free solder: Sn-Ag-Cu (tin, silver and copper) has a higher melting point (approx. 217°C) than standard solder Typically the melt
 
 
  ing point is 30~40 °C higher. When servicing, use a high temperature soldering iron with temperature limitation function and set it to 
 
 
  370 ± 10 °C.
 
 
•  Be precautious about lead free solder. Sn-Ag-Cu (tin, silver and copper) will tend to splash when heated too high (approx. 600°C or 
 
     higher).
 
 
•  Use lead free solder for the P.C.Board (specified on it as “PbF”) which uses lead free solder. (When you unavoidably use lead solder, 
 
 
  use lead solder after removing lead free solder. Or be sure to heat the lead free solder until it melts completely, before applying lead 
 
 
  solder.)
 
 
•  After solder to double layered P.C Boards, check the component side for excess solder which may flow onto the opposite side.
 
 
About the identification of the lead free solder P.C.Board.
 
 
 For the P.C.Board which applies lead free solder, the symbol as shown in the figure below is printed or stamped on the surface or the 
back of P.C.Board.

Notes on repairing
•  In case of fuse opening inside the projector, Do not turn the projector on just replacing the fuse with new one because there 
might be a possibility to have smoking or firing hazard. Turn it on after solving the main cause of fuse opening.
• After repairing, confirm that the projector operates correctly.
• Pay attention to handle the projector as customer's personal settings have been remaining inside the projector.  
Cautions when transporting
•  When transporting the projector, handle it with care and avoid excessive vibration and impacts. Doing so may damage the 
internal parts and result in malfunctions.
• Do not transport the projector with the adjustable feet extended. Doing so may damage the adjustable feet.
  Do not move or transport the projector with the wireless module (Model No.: ET-WML100) of the optional accessories 
 attached. Doing so may damage the wireless module.
Cautions when installing
l  Do not set up the projector outdoors.
• The projector is designed for indoor use only.
l  Do not set up the projector in the following locations.
•  Places where vibration and impacts occur such as in a car or vehicle: Doing so may cause damage to internal components 
or malfunction.
•  Locations near the sea or areas affected by corrosive gas: Corrosion may damage internal components or cause the 
  projector to malfunction.
•  Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare cases due to 
  the heated air from the air exhaust port or the hot or cooled air. Make sure that the exhaust from the projector or other 
  equipment, or the air from the air conditioner does not blow toward the front of the projector.
•  Places with sharp temperature fluctuations such as near lights (studio lamps): Doing so may shorten the life of the lamp, or 
result in deformation of the outer case due to heat, which may cause malfunctions.
  The operating environment temperature of the projector should be between 5 °C (41 °F) and 40 °C (104 °F) when using it at 
  elevations lower than 1 400 m (4 593') above sea level, between 5 °C (41 °F) and 35 °C (95 °F) when using it at high 
  altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level), and between 5 °C (41 °F) and 30 °C (86 °F)    
  when using it at high altitudes (between 2 700 m (8 858') and 3 000 m (9 843') above sea level).
•  Near high-voltage power lines or near motors: Doing so may interfere with the operation of the projector.
l Be sure to ask a specialized technician or your dealer when installing the projector on a ceiling.
   The requires an optional Ceiling Mount Bracket is required. Be sure to use the Projector Mount Bracket together with 
  the ceiling mount bracket for high ceilings or low ceilings.
  Model No.: ET-PKL100H (for high ceilings), ET-PKL100S (for low ceilings), ET-PKL430B (Projector Mount Bracket)
l When using the projector in the elevation of below 1 400 m (4 593'), make sure [High land] is set to [Off].
  Failure to do so may shorten the life of the internal parts and result in malfunctions.
l When using the projector in the elevation of above 1 400 m (4 593') and below 2 700 m (8 858'), 
    make sure [High land] is set to [On 1].
  Failure to do so may shorten the life of the internal parts and result in malfunctions.
l When using the projector in the elevation of above 2 700 m (8 858') and below 3 000 m (9 843'), 
    make sure [High land] is set to [On 2].
  Failure to do so may shorten the life of the internal parts and result in malfunctions.
l Do not install the projector at elevations of 3 000 m (9 843') or higher above sea level.
  Failure to do so may shorten the life of the internal parts and result in malfunctions.

l Do not tilt the projector or place it on its side.
  Do not tilt the projector body more than approximately ±30 degrees vertically or ±15 degrees horizontally. Over tilting may 
  result in shortening the life of the components.
l Cautions when setting up the projector
•  Do not stack the projectors.
•  Do not use the projector supporting it by the top.
•  Do not block the ventilation ports (intake and exhaust) of the projector.
•  Avoid heating and cooling air from the air conditioning system directly blow to the ventilation ports (intake and exhaust) of 
the projector.
•  Do not install the projector in a confined space.
  When placing the projector in a confined space, a ventilation and/or air conditioning system is required. Exhaust heat may  
  accumulate when the ventilation is not enough, triggering the protection circuit of the projector.
