If the lamp stops working
and needs to be
replaced, there is the
danger that the lamp
may already be broken.
If replacing the lamp of a
projector which has been
installed on the ceiling,
you should always
assume that the lamp is
broken and handle it with
extreme care during
removal. Furthermore,
you should stand to the
side of the projector, not
underneath it.
Press to turn on
the power.
Press to display
the configuration menu.
The lamp operating time
must always be reset after
the lamp has been replaced
with a new one.
The projector has a built-in
lamp operating time counter.
A replacement message is
displayed when the counter
reaches a certain amount.
