Replacing the lamp unit
Precautions on lamp unit replacement
Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.

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.
Philips screwdriver is necessary when replacing a lamp unit.
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). 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.
Indication after 1 300 hours 2 (with the lamp output set at “HIGH”)
When lamp unit used hours have reached 1 300 hours 2 , lamp monitor
(LAMP) light up including standby state.
Further, an on-screen indication will appear for about 30 seconds as
shown in the diagram on the left, recommending replacement of lamp unit.
(The indication on the left diagram will disappear after about 30 seconds or
when either control button on the upper panel of main unit or remote
control button is operated.)
After the time of 1 500 hours
1 , the on-screen indication will not disappear
unless the menu (MENU) button is operated.
