11.2. Timing of Lamp Unit Replacement

The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 2 000 hours. However, it
may happen that the lamp becomes dead (will not light) by the time of 2 000 hours depending on the characteristics of individual
lamps and working conditions (lamps may reduce their life affected by the times of lighting and the intervals between previous
lighting and next lighting). Therefore, it is strongly recommended for the user to keep a spare bulb. If a lamp unit has not been
replaced after 2 000 hours of operation have elapsed, the lamp will turn off automatically. when the operating time for all of the
lamps reaches 2 000 hours or more, the power will turn off automatically approxmately 10 minutes after it is turned on, and the
projector will switch to standby mode.
