Reliability Information
Average monthly projection time: 58.3 hrs/month
2.65 hrs/day x 22 working days/month
Failure Rate
1st year: 0.0024 cases/unit/month
2nd year: 0.0029 cases/unit/month
3rd year: 0.0036 cases/unit/month
The failure rate of a projector increases with its
total power-up time. This is due in part to the
failure characteristics of optical engines in
projectors.
Lamp Life
Normal Mode: 3,000 hrs
Eco Mode: 4,000 hrs

Slide 8
Lamp Near-end/End Alerts
There is no near-end alert.
The lamp end alert occurs when the machine
calculates that the life time has expired.
End alert will appear 30 hours (in Normal mode)
before suggested replacement of lamp.
If the user switches between modes, the machine
calculates when to display the alert based on
how long the lamp was used in each mode.

Slide 9
Disposal of Broken Lamps
Projector lamps normally contain mercury
vapour.
These lamps can rupture due to impact or being
used longer than their life expectancy.
The time that the breakage will occur differs
widely for each lamp and its circumstances of
use.
These lamps must be disposed of in accordance
with local environmental regulations.
