Light-source Lamp and Lamp Usage Time
The life of light-source lamps used for this unit is about 4000 hours when running this unit in low lamp mode.
• When the lamp power is set to Low, the lamp life is approximately 4000 hours. This average lamp life is not
guaranteed and may not reach 4000 hours depending on the operating conditions.
Deterioration progresses rapidly when the remaining lamp usage time is short. Get ready or replace with a new
lamp when the accumulated usage time exceeds 4000 hours. Depending on the operating conditions, the lamp
may have to be exchanged earlier.
If the image is dark or if the color tone is abnormal, replace the lamp as soon as possible.
•You can also check the accumulated hours of usage. Please refer to Lamp Time in the Information menu.

ABOUT LAMP REPLACEMENT
If this unit is installed in a constricted place, attempting to replace the lamp in that place may cause injury. Move this
unit to a place large enough to perform work.
Use only genuine replacement parts for the lamp unit. Otherwise, malfunction may occur. Also, never attempt to re-
use an old lamp unit. This may cause marked performance deterioration or lamp blowout, thus leading to unit
malfunction. Broken pieces of the lamp outside this unit may also cause injuries during lamp unit exchange.
Do not replace the lamp immediately after this unit has been used. The temperature of the lamp is still high and this
may cause a burn. Allow a cooling period of 1 hour or more before replacement.
Before replacing the lamp unit, pull out the power plug from the outlet and wait until the STANDBY/ON led is still light
red. Replacing a lamp with the plug connected to the outlet may cause injuries or electric shocks.
