CLEANING AND REPLACING THE NOISE FILTER
The noise filter is found only on early models of the DP4100. Follow the
instructions below to determine if your projector contains a noise filter. The
DP4200 does not use a noise filter.
You should rinse off the noise filter after every 100 hours of use. If you are
using the projector in dusty areas, clean it more frequently. If you are
experiencing a high number of over-temperature problems, you may need to
clean the filter more often.
CAUTION! Be sure to turn off the main AC power before opening the
projector.
1 Remove the two screws on the lower front panel and snap the front panel
off (see Figure 5-1). Remove it carefully, as it is attached to the projector
with a ribbon cable.
2 Press in on the tabs on the upper front sides of the projector and pull up
gently on the top panel to remove it. Remove it carefully, as it is attached
to the projector with a ribbon cable.
