Replacement of lamp unit
Precautions on lamp unit replacement
Be careful when handling a light source lamp.
The lamp unit has high internal pressure. If
improperly handled, 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.
• A lamp unit is an optional part. Contact
the dealer.

Attention
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

(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.
Indication after 1 300 hours

"HIGH")
When lamp unit used hours have reached 1 300
hours
2
, lamp monitor (LAMP1 or LAMP2) light
up including standby state.

about 30 seconds as shown in the diagram on the
right, recommending replacement of lamp unit.
(The indication on the below diagram will
disappear after about 30 seconds or when either
control button on the rear of main unit or remote
control button is operated.)
After the time of 1 500 hours
1

indication will not disappear unless the menu
