In order to use the television for a long time
This television uses a lamp to project the picture onto the screen. Before using this television, please read the safety cautions and information about this television which
are summarized below (1 to 10).
1. When the power is turned on, the warming up
commences
This television uses a lamp to project the picture onto the screen. Once the lamp
has warmed up, you can enjoy the pictures at their full brightness. What happens
when the power is turned on is explained below. Immediately after the power is
turned on, since the lamp has not had time to warm up, the picture is displayed
only dimly on the screen. As the lamp warms up, the picture becomes brighter. It
takes approximately one minute for the lamp to warm up to it's normal operating
temperature. There are 2 LED indicators on the front panel of the television that
can be used as a guide. When the POWER button is pressed, the LAMP LED
indicator blinks in orange for approximately 1 minute at approximately every 2
seconds, and then goes out.
· It is impossible to turn the power off during this period. After 1 or more
minutes have passed, you can turn off the power.
2. Cooling the inside of the television and the lamp
Cooling is also performed while the television is being shut down.
When the POWER button is pressed to turn off the power, the following
operations are performed. When the television is turned off, the picture on the
screen disappears gradually within approximately 5 seconds. Once the screen is
dark, cooling is performed for approximately 90 seconds. When the cooling is
being performed, the LAMP LED indicator on the front panel blinks in orange at
approximately every 3 seconds. The television can not be operated while the
cooling is being performed. After the cooling has been performed for 90
seconds, the power is turned off. Do not remove the electrical plug until after
the cooling process has completed. If the electrical plug is removed before the
cooling process has completed, the internal circuits and lamp may overheat
leading to the life of the lamp being shortened and the possibility of malfunctions.
· When it is hotter, the cooling fan works harder to cool the lamp. The noise of
the fan bebomes bigger then but it is not malfunction.
· You can cancel to turn off the power by pressing the POWER button before
the picture on the screen disappears completely.
Do not block the ventilation holes.
3. The lamp is a consumable item
Replace the lamp when it has blown or when the picture becomes dark. The lamp
is a user replaceable item. The lamp must be recycled. For a detailed explanation
on how to recycle the lamp, refer to the Appendix and the instructions that are
included with the replacement lamp kit. The life of the lamp changes depending
on the atmospheric temperature and altitude in which the TV is being used.
Do not turn the power on and off repeatedly in a short amount of time.
It subjects the television and the lamp to stress and may lead to malfunctions and
the life of the lamp being shortened.
4. Caution! Warm air from the air ducts
This unit has an air duct for cooling. The duct will blow warm air while the
television is operating. When placing the television, make sure not to locate it too
close to wallpaper. The warm air could cause the color of the wallpaper to change.
Also, take care to keep children and pets away from the warm air ducts. Long
exposure to the warm air from the ducts could cause a minor burn.
5. Caution! Moving this television
When lifting this television, Do not hold by the screen frame. Holding the screen
frame could cause it to detach, causing the television to fall.
6. Do not replace the lamp immediately after use
The lamp becomes extremely hot during use. If the lamp is touched immediately
after use before it has a chance to cool down, there is a danger of burns. Be careful
when handling the lamp.
7. Do not touch the lamp glass
If the lamp is used when there is dirt from fingers on the lamp glass, there is a
possibility of the lamp breaking. Be careful not to touch the lamp glass.
8. ILA element characteristics
Do not project still pictures or pictures that have still segments for a long period of
time. The still parts of the picture may remain on the screen. This is a
characteristic of ILA elements and not a malfunction. The picture will disappear
over time.
9. Condensation
When a heater is turned on or the television is moved from a cold place to a hot
place, droplets of water may form on the lamp and screen. This is called
condensation. If the television is used while this condensation is still present, the
picture may seem distorted, and the inside of the screen may become dirty. In this
case, wait until the condensation has gone before using the television.
10. Usable Time
Do not keep the TV on for more than 24 hours consecutively. There is a
possibility of the life of the lamp being shortened.
Installation requirements
To avoid overheating, ensure the unit has ample room.
