Fig. 5-1

Note:

1. If the Lamp time exceeds 10,000 hours, when turning

on the power (Lamp ON), the display as shown in Fig.52 appears for about 5 minutes and LAMP LED lights up.

Lamp Replacement Procedure:

1. Press the POWER button on the remote to turn off the power.

2. Wait for about 1 minute until the cooling fan stops.

Note:

The lamp cooling fan will continue to operate for about 1 minute after the power is turned off. Do not unplug the AC Cord from the outlet until the fan has stopped. Avoid interrupting the power by using circuit breakers or switchable power strips.

3. After the cooling fan has stopped, unplug the AC Cord from the outlet.

Note:

Please wait more than one hour before replacing the lamp.

[ Forced cooling function ] If you need to replace the lamp more urgently:

• The Projection display has a forced cooling feature.

After the POWER button is turned OFF, and sometime during about the first minute of the normal cooling fan operation, press the VOLUME UP button on the unit and CH UP key on the remote at the same time for more than 5 seconds. The cooling fan will operate for about 10 minutes. (LAMP LED will flash 5 times every 5 second and POWER LED will flash red for 10 minutes.)

4. Remove the Front Cover Unit from the latches.

5. Remove the Lamp Cover by loosening the Screw.

Fig. 5-2

2. Due to variation in the way each lamp is used, the lamp may need to be replaced before the maximum 10,000 hour limit is reached. These variations include the number of times and the duration the lamp is lit, prolonged use in excess of 24 hours, and any mechanical shock the bulb may accidentally experience. In situations where the use of this product is critical we recommend keeping a spare bulb on hand.

WARNING:

The high-pressure lamp may explode if not properly handled. The lamp is hot immediately after use. Touching it directly may cause burns. Please allow the lamp to cool before handling or replacing the lamp unit. Avoid touching the glass portion of the bulb with your fingers. Natural oils from your skin can cause a “hot spot” to develop, which can cause the bulb to crack when it gets hot. In case the bulb is accidentally touched, the area should be carefully cleaned using isopropyl alcohol and a soft lint free cloth or cotton ball.
