WARNING indicator that warns you when the projector
is too hot, and two LAMP REPLACEMENT indicators
that warn you when to change a lamp.
• If a problem occurs, either the TEMPERATURE
WARNING indicator or the LAMP REPLACEMENT
indicators will light up red. After turning off the power,
follow the procedures given below.
• If the TEMPERATURE WARNING indicator lights up, follow the above possible solutions and then wait until the projector has
cooled down completely before turning the power back on. (At least 5 minutes.)
• If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicators may be
triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet and put it back
in again.
