Using the Desktop Projector 5500
3-5
TEMP
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 following checks while
you allow the projector to cool:
• Make sure that the room temperature is below 95° F (35° C).
• Check the intake and exhaust vents. Clear any obstruction to the air flow.
• Make sure that 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 service.
After the projector returns to its normal operating temperature, you must
turn the main power switch off and back on to clear the over temperature
indicator. Press the STANDBY/ON key on the control panel to relight the
lamp.
NOTE: The remote control’s STANDBY/ON button will 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. It will
show solid 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 power off before attempting to
change the lamp. See page 4-2 for instructions on changing lamps. The lamp
and surrounding parts get very hot. Use appropriate care when changing
lamps.
