Related Messages
When the unit's power is ON, messages such as those shown below may be displayed. When
any such message is displayed on the screen, please respond as described below.
Note 1: Although this message will be automatically disappeared after around 3 minutes, it will be
reappeared every time the power is turned ON.
Note 2: Lamps have a finite product life. Lamps are characterized by the fact that, after long hours of
usage, a lamp will no longer light up, or the lamp will break or burst, etc. This unit is equipped
with an automatic shut-down function, such that the power will automatically be turned OFF
when lamp usage time has reached 2,000 hours. Please be aware, however, that among lamp
types, there are major differences in product lifetimes; a lamp may thus fail to light even prior
to the functioning of the automatic shut-down function of this unit.
