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 controlÕs 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.

Maintenance
There is very little effort required to care for and maintain your
Desktop Projector. Common sense and periodic maintenance will
ensure top performance.
An optional maintenance kit is available. It includes the following
materials:
¥ Two Halogen lamps
¥ Lens cleaning fluid
¥ Lens tissue
¥ Top and front air filters
¥ Can of compressed air
The lamps, lenses, mirrors, and LCD panel have been carefully
aligned at the factory to give you the clearest, brightest image
possible. However, mishandling your projector can misalign or
damage the optical elements. Be careful when you use or move
your projector.
CAUTION! The projector contains sensitive circuitry and
optics. Protect it from potential fluid spills.
From time to time, youÕll need to clean the optics on the lens and
mirror assembly. To clean the projection lens or the mirror:
1. Take a piece of lens tissue and form it into a loose swab. Wet it
with lens cleaning fluid or denatured alcohol, and gently move
it over the lens or mirror surface.
2. Take a part of the lens tissue that you havenÕt touched, and
repeat the process, going over the lens or mirror in another
direction.

3. Repeat steps 1 and 2 until no smudges or particles can be seen
when the lens or mirror is illuminated by a strong light. DO
NOT LOOK DIRECTLY INTO THE LENS WHEN THE
LAMP IS ON!
If the lens or mirror is extremely dirty, use several pieces of lens
tissue. Water may be used if denatured alcohol is unavailable.
CAUTION! Do not use acetone to clean the lensÐit may
remove the paint from the metal near the lens or mirror mount
and leave a residue on the glass surface.
Switching Lamps
If your projector lamp burns out during a presentation, the
LAMP SELECTOR switch allows you to quickly change to a
backup lamp.

You can switch lamps on the fly, without turning off your
projector or interrupting your presentation. Push the LAMP

Replacing Lamps
Follow these steps to remove the lamp and install a new one.
Removing the Old Lamp
1. Leave the projector running with the lamp off for at least 6
minutes before you change the lamp (to do this, press the lamp
button to turn the lamp off). This allows the fan to cool the
lamp chamber. Do not open the lamp chamber until the
projector has cooled.
2. After the lamp chamber has cooled sufficiently, turn off the
projector, unplug the power cord from the wall socket, and
remove the power cord from the projectorÕs power receptacle.
As a safety feature, you cannot open the lamp chamber unless
the cord is removed.
3. Move the lamp chamber latch to the right. The cover will
unlatch and partially open.

when you open the lamp chamber or change the lamp. Make sure
that the fan has cooled the lamp and chamber for at least 6
minutes.

cloth or tissue.
5. Find the lamp release lever at the base of the ceramic lamp
socket. Push the lever to the outside to release the lamp.
