Replacement of lamp unit

WARNING
• Wait until the lamp is cooled sufficiently before replacing the lamp unit.
• Make sure that all four lamp units are installed.
• Replacement of the lamp unit should be carried out by a qualified technician.
• Do not remove any screws (such as the black screws) other than those indicated when replacing the

Precautions on lamp unit replacement
• Be careful when handling a light source lamp. The lamp unit has high internal pressure. If improperly handled,
failure might result.
• A used lamp unit may burst if it is handled violently. For disposition of used lamps, request an industrial waste
disposal contractor.
• If you continue to use a lamp after the replacement time, the lamp may break.
• Phillips screwdriver is necessary when replacing a lamp unit. Take care not to slip your hand when using a
screwdriver.
Attention
• A lamp unit is an optional part. Contact the dealer.
Replacement Lamp Unit model No.: ET-LAD12K (single bulb), ET-LAD12KF (4 bulbs)
• Other lamps than specified above cannot be used. Be sure to use the specified lamp.
Timing of lamp unit replacement
The lamp used for the light source has its due life. The life of the lamp used in the main unit is 2 000 hours.
However, it may happen that the lamp becomes dead (will not light) by the time of 2 000 hours depending on the
characteristics of individual lamps and working conditions (lamp life is 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 a lamp unit has not been replaced after 2 000 hours of operation have elapsed, the lamp will turn off
automatically. When the operating time for all of the lamps reaches 2 000 hours or more, the power will turn off
automatically approximately 10 minutes after it is turned on, and the projector will switch to standby mode.
Attention
• Clean and replace the air filter when replacing the lamp units. (pp. 112-113)
Indication after 1 800 hours
When lamp unit used hours have reached 1 800 hours, lamp monitor (LAMP1, LAMP2, LAMP3, or LAMP4)
light up including standby state.
Further, an on-screen indication will appear for about 30 seconds as shown in the diagram, recommending
replacement of lamp unit. (The indication will disappear after about 30 seconds or when either control button
on the main unit or remote control button is pressed.)
After 2 000 hours, the on-screen indication will not disappear unless the menu (MENU) button is pressed.
