explosion might result.
A used lamp unit may burst if it is handled violently.
For disposition of used lamps, request an industrial waste disposal contractor.
Do not reset the cumulative time, except when the lamp unit has been replaced with a new unit.
If you continue to use a lamp after the replacement time, the lamp may break.

Take care not to slip your hand when using a screwdriver.

Attention
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 1 500
hours
1
(when lamp output is HIGH and lamp selection is DUAL). However, it may happen that the lamp
becomes dead (will not light) by the time of 1 500 hours
1
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 your lamp unit is not replaced after 1 300 hours
2
(with the lamp output set at “HIGH”), power supply will be
turned off automatically at the time of 1 500 hours
1
, entering a standby state. After 1 500 hours
1
of initial
lighting, power supply is turned off automatically about 10 minutes later, entering a standby state even if it is
turned on again.
