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.
