Precautions on lamp unit replacement

WARNING!

When replacing the lamp, allow it to cool for at least one hour before handling it.

Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.

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.

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”)

REPLACE LAMP

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.

1 This time period is 4 000 hours when long life lamp units are used. 2 This time period is 3 800 hours when long life lamp units are used.
