Chapter Three
• 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 key on the control panel to relight the lamp.
NOTE: The Cyclops remote control’s
/O
key 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.
Replace Lamp
The indicator will illuminate if the projection lamp burns out. If the
lamp has burned out, you cannot continue your presentation until you
replace the lamp assembly.
CAUTION! If the lamp fails during a presentation, make sure that the
projector cools for at least five minutes with the projector off before
attempting to change the lamp. See page 5-1 to change lamps. The lamp
assembly gets very hot. Use appropriate care when changing it.
USING THE CYCLOPS REMOTE CONTROLS
The Cyclops remote control contains all the key functions available on the
DP4100/4200 control panel as well as several additional features. The
Cyclops Quick Remote allows you to control several of the projector's most
popular features.
For best results, aim the remote control at the projection screen or at the
projector’s front panel. Do not obstruct the red infrared eye located on the
front of the projector.
