Replacing the Light-Source Lamp
The light-source lamp has its service life. It is approximately 1000 hours.
When the light-source lamp approaches the end of its service life, degradation progresses rapidly.
The number display on the projector and the message on the screen warn you that replacement of the lamp is required.
■ When the lamp’s use hours exceed 900 hours
In this case, the light-source lamp needs to be replaced.
• To cancel the message “Lamp replacement,” press the EXIT button.
• Each time the projector is turned on, the message appears.
■ When lamp’s use hours has reached 1000 hours
• To cancel the message “ Warning Lamp replacement,” press the EXIT button. However, the same massage will appear
every one hour.
• Once the projector is turned off, it does not turn on until the light-source lamp is replaced with a new one.
The specified lamp replacement period is 1000 hours, but depending on use conditions, the replacement period may vary. If
video image is dark and its color tint is abnormal even after you have adjusted color tint and brightness, replace the light-source
lamp earlier.
For replacing the light-source lamp, consult your dealer.
CAUTIONS
• If the projector is set up in a limited place which is unsuitable for work, and if you perform replacement work there, this could cause injury.
Move the projector to a place large enough for work, and then replace the light-source lamp.
• Use a genuine product for the light-source lamp. If you use other than a genuine product, this could cause a malfunction. Also, never use an
old light-source lamp. This could cause marked degradation in performance or the lamp could even explode, possibly damaging the projector
and/or injurying the operator.
• Do not replace the light-source lamp immediately after the projector has been used. The temperature of the light-source lamp is still high and
could cause a burn. Allow a cooling period of one hour or more before performing replacement.
• Before starting light-source lamp replacement work, turn off the MAIN POWER switch, and disconnect the power cord from the wall outlet. If
you perform the replacement work with the power cord connected, this could cause injury or electric shock.
• The light-source lamp used in this projector is a high pressure xenon lamp. Be careful when disposing of the light-source lamp. If anything is
unclear, please consult your dealer.
