bottom edge first and snapping the top into place. Do not force.
Figure 4-1. Replacing Keypad Batteries
The high brightness of the DLV 1280 projector is provided by a 500 watt Xenon
lamp permanently assembled in a polymer housing and mounted to a pre-aligned
bracket. When the lamp approaches its lamp limit—as defined in the Service-
Lamp menu—the entire lamp assembly (module plus bracket) should be
replaced. Contact your dealer or Electrohome for the Lamp/Filter kit needed.
If you want to know how many hours have been logged on your lamp so far, go
to either the Status menu or the Service-Lamp menu. "
Lamp Hrs
" indicates the
total number of hours the lamp has been used.
NOTE: As the lamp nears its Lamp Limit (as set in Service-Lamp), a lamp timer
message may appear on screen to warn that the lamp needs to be replaced. To
make sure that this warning appears, enter “
Yes
” for the Lamp Message option
in the Preferences menu.
WARNING
Never attempt to remove the lamp when it is hot. The
lamp is under great pressure when hot and may explode,
causing personal injury and/or property damage. Allow to
cool completely and handle by the housing only.
Follow the instructions below to replace the lamp.
WARNING
For best results, the lamp should be replaced by a
qualified service technician only.
Turn off the projector

turn off before continuing with Step 2. This will take about five minutes.
Unplug the projector

time for the lamp to cool completely.
