Replacement of lamp unit

CAUTION

Wait until the lamp is cooled sufficiently before replacing the 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.

Attention • A lamp unit is an optional part. Contact the dealer.

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 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 2

(with the lamp output set at "HIGH")

When lamp unit used hours have reached 1 300 hours 2, 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 1, the on-screen indication will not disappear unless the menu (MENU) button is operated.
