Recommendation

Should the air filter become clogged with dust particles, it will reduce the cooling fan’s effectiveness and may result in internal heat build up and short lamp life. We recommend clean- ing the air filter after the projection lamp is replaced.

Refer to “Air Filter Cleaning”.

How to check lamp used time

The LAMP REPLACE indicator will light when the total lamp used time (corresponding value) reaches 2,500 hours. This is to indicate that lamp replacement is required. The total lamp used time is calculated by using the below expression;

Total lamp used time = Teco + Tnormal x (1.666) Teco: used time in Eco mode

Tnormal: used time in Normal and Auto mode You can check the lamp counter following procedure.

1 Press and hold the POWER ON-OFFbutton on the projector or the remote control unit for more than 20 seconds.

2 The projector used time and lamp used time will be displayed on the screen briefly.

You can also check "Lamp Counter" in "Setting Menu". This value is actual lamp used time.

"Lamp Time" = Teco + Tnormal
