Chapter 3 • Using the Desktop Projector
CAUTION! DO NOT TURN OFF THE PROJECTOR!
Leave the power on so that the fans can cool the projector.
If an OVERTEMP condition occurs, perform the following
checks while you allow the projector to cool:
• Verify that the room temperature is below 80° F (27° C).
• Check the intake grills and exhaust vents. Clear any
obstruction to the air flow.
• Check the filter elements. Clean or replace them if
necessary. For more information, please refer to Chapter 4.
• Check the rear and side exhaust vents. If the projector has
reached an OVERTEMP condition and the fans are
working, you should feel a strong rush of hot air from the
vents. If the fans are not working, the projector needs
service.
After the projector returns to its normal operating temperature,
the OVERTEMP light will go out. To turn the lamp back on
again, you must press the LAMP key on the control panel.
Note: The remote control’s LAMP key will not function after
an OVERTEMP condition until the lamp is turned on from the
control panel.
REPLACE LAMP Alert Light
The REPLACE LAMP alert light will illuminate if one or both of
the active projection lamps have burned out. It will also
illuminate if the lamp selector is not fully engaged.
If one lamp has burned out, you can continue your presentation
with the alternate lamp. The REPLACE LAMP indicator remains
on to remind you to replace the burned out lamp.
