further, projection will stop automatically. Make sure there is
plenty of space around the projector for ventilation. Clean or
replace the air filter if necessary (see page 50).
If you are using the projector at an altitude above 4900 feet (1500
meters), turn on High Altitude Mode so the fan can cool the
projector properly (see page 45).
The projector is too hot, which turns off the lamp automatically.
Let the projector cool for five minutes, then turn it back on. Make
sure there is plenty of space around the projector for ventilation.
Also, clean or replace the filter if necessary (see page 50).
If you are using the projector at an altitude above 4900 feet (1500
meters), turn on High Altitude Mode so the fan can cool the

you have a spare lamp handy. If you just replaced the lamp, you
