Light-source Lamp and Lamp Usage Time
The light-source lamp has a service life. The life of lamps used for this unit is about 2000 hours.
●
The lamp life of 2000 hours is merely the average life span of lamps and we do not provide any guarantee for this figure. The
lamp life may not reach 2000 hours depending on the operating conditions.
When the light-source lamp approaches the end of its service life, deterioration progresses rapidly. Get ready or replace with a
new lamp (lamp unit) when the accumulated lamp usage time exceeds 1900 hours. Depending on the operating conditions, the
lamp may have to be exchanged earlier. If the image is dark or color tone abnormal, replace the lamp as soon as possible. You
can also check the accumulated hours of usage. Please refer to the “Lamp Time” item of the “Information” menu. (

Replacing the Lamp
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 the 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 unit 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 while the [STAND BY] indicator is still on. Replacing
a lamp with the plug connected to the outlet may cause injuries or electric shocks.
