Important Information
  Fire and Shock Precautions  
•  Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 4 inches (10cm) of space between your projector and a wall.•  Do not try to touch the exhaust vent as it can become heated while the projector is turned on and immediately after the projector is turned off.
•  Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not at-tempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immedi-ately and have the object removed by a qualified service personnel.•  Do not place any objects on top of the projector.•  Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.•  The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply fits this requirement before attempting to use your projector.•  Do not look into the lens while the projector is on. Serious damage to your eyes could result.
•  Keep any items (magnifying glass etc.) out of the light path of the projector. The light path being projected from the lamp is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lamp, can cause unpredictable outcome such as a fire or injury to the eyes.•  Do not block the light path between the light source and the lamp with any objects. Doing so could cause the object to catch on fire.•  Do not place any objects, which are easily affected by heat, in front of the projector lamp or a projector exhaust vent.Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light output and exhaust.•  Do not use a spray containing flammable gas to get rid of accumulated dust and dirt on the aspherical mir-ror or lens.•  Handle the power cord carefully. A damaged or frayed power cord can cause electric shock or fire.-  Do not use any power cord other than the one supplied.  -  Do not bend or tug the power cord excessively.-  Do not place the power cord under the projector, or any heavy object.-  Do not cover the power cord with other soft materials such as rugs.-  Do not heat the power cord.-  Do not handle the power plug with wet hands. 
Place the projector in a horizontal position
The tilt angle of the projector should not exceed 5 degrees, nor should the projector be installed in any way other than the desktop and ceiling mount, otherwise lamp life could decrease dramatically.

A Lamp Characteristic
The projector has a discharge lamp for special purposes as a light source.A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on and off will increase the possibility of its lower brightness.
 CAUTION:
•  DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off and then disconnect the power cord. Allow at least one hour for the lamp to cool before handling.•  When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projec-tor. Glass fragments could fall if the lamp has been burned out.
