Lamp Replacement
The LAMP REPLACE indicator will light when the total
lamp used time reaches 3,000 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 (1.5)
teco: used time in Eco mode
tnormal: used time in Normal/Auto1/Auto mode
