Precautions for use
Cautions on use
■■In order to view clear video images
zzClear, high contrast video can be viewed when curtains are closed and lights near the screen are extinguished in order to stop light from reaching the screen.
zzIn some rare cases, depending on the usage environment a “flickering” may appear on the screen due to the effects of air from the exhaust port or hot/cold air from air conditioners. Do not set up this projector in a situation where air from the exhaust of this device or other devices, or air from air conditioners is circulated to the front of this device.
zzThe focus of high brightness projection lenses may not be stable immediately after turning power on due to the effects of heat from light coming from light sources. Focus stabilizes 30 minutes after video projection starts.
■■Do not touch the surface of the projection lens with bare hands.
If fingerprints or dirt are left on the projection lens, they will be enlarged and projected and will prevent the viewing of clear video images. Also, always replace the lens cover when not using the projector.
■■About LCD panels
LCD panels are manufactured using high precision technologies, but in some cases they may have dead pixels, or permanently lit pixels. Please understand that this is not a fault.
Also, projecting a still image for extended periods of time may lead to afterimages on LCD panels. Please be aware that in some cases these afterimages may not disappear completely.
■■About optical components
If using in an environment with a high temperature, or where dust or tobacco smoke is present, the replacement cycle of optical components such as LCD panels and polarizing plates may shorten even after less than one year of use. For more details, please contact your dealer.
■■About the lamp
This product uses an internal high pressure mercury lamp for the light source. High pressure mercury lamps have the following characteristics. zzBrightness decreases with usage time.
zzIn some cases, the lamp may make a large sound, crack, and reach the end of its lifespan as a result of shocks, damage, and deterioration related to usage period.
zzLarge disparities occur in lifespan due to individual properties and usage conditions. Lifespan is especially affected if you use the lamp continuously for more than 6 hours or switch it ON/OFF rapidly.
zzVery occasionally the lamp may crack after starting projection.
zzThe possibility of cracking increases as the lamp nears the end of its lifespan. zzIf the lamp cracks, gas may be leaked from inside and smoke may be seen. zzPlease prepare a spare lamp in advance.
