TEMP indicator The TEMP indicator illuminates if the projector overheats or
if the air-filter door on the bottom of the projector is open.
A thermostat automatically turns off the power to the lamp
until the projector cools.
If an over-temperature condition occurs, perform the follow-
ing checks while you allow the projector to cool:
• Make sure the room temperature is below 95°F (35°C).
• Check the intake and exhaust vents. Clear any obstruction to
the airflow.
• Make sure the fans are working. If the projector has reached
an over-temperature condition and the fans are working,
you should feel a strong flow of hot air from the top vent
and a strong rush of air directly into the front and rear of the
projector. If either fan is not working, the projector needs
s e r v i c e .
After the projector returns to its normal operating tempera-
ture, you must turn the main power switch off and back on
to clear the over-temperature indicator. Press the STAND-
BY/ON key on the control panel to relight the lamp.
Note: The remote control STANDBY/ON button does not
function after an over-temperature condition until the main
power switch is turned off and on and the lamp is turned on
from the control panel.
LAMP indicator The LAMP indicator flashes red if the air-filter door is
removed. The lamp indicator glows a steady red if the lamp
burns out.
Caution! If the lamp fails during a presentation, make sure
that the projector cools for a few minutes with the projector
off before you attempt to change the lamp. See Chapter 4,
M a i n t e n a n c e for instructions on changing the lamps. The
lamp and surrounding parts get very hot. Use appropriate
care when changing the lamps.
