• The projector cannot be turned on during the cooling period with the POWER

• When the On start function is on, this projector is turned on automatically by
connecting the AC power cord to an AC outlet. (See page 45 for the On start
function.)
• Do not operate the projector continuously without rest. Continuous use may result
in shortening the lamp life. Turn off the projector and give it a rest about an hour in
every 24 hours.
• This projector monitors internal temperature and automatically controls the
running speed of the cooling fans.
