Replacement of lamp unit
Precautions on lamp unit replacement
Be careful when handling a light source lamp.
The lamp may burst if it is hit by solid objects or
if it is dropped because of high air pressure
inside the bulb.
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.
Lamp unit model No.: ET-LAD7500 (single
bulb), ET-LAD7500W (double bulbs)
Rating: 300W 65V
• Other lamps than specified above cannot be
used. Be sure to use the specified lamp.
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 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,
power supply will be turned off automatically at the
time of 1 500 hours, entering a standby state. After 1 500
hours 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
When lamp unit used hours have reached 1 300 hours,
lamp monitor (LAMP1 or LAMP2) light up including standby
state.
Further, an on-screen indication will appear for 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, the on-screen indication will
not disappear unless the menu (MENU) button is operated.
REPLACE THE LAMP
CAUTION
Wait until the lamp is cooled sufficiently before replacing the lamp unit.
