Remote Control Functions
The remote control performs the following functions:

 Duplicates the functions of the projector buttons including
adjusting the on-screen buttons.

 Controls the computer connected to the projector by navigating
through the computer directories and opening and closing files.
IMPORTANT:  To operate a computer using the remote control,
the remote control Y-cable (included with the Multimedia Adapter)
must be used. Connect the 8-pin connector cable to the appropriate
connector on the Multimedia Adapter and connect the USB
connector to the USB connector on the computer (preferred) or the
RS232 connector to the serial connector on the computer. Do not
connect both the USB and RS232 connectors to the computer.

require an additional driver when used with the RS232 connector.
This driver can be found on the CD-ROM that came with your
projector.

Chapter 5
Care and Maintenance
This section explains how to care for and maintain your Compaq
projector during normal everyday use.
Protecting the Projector
To protect your projector from overheating and other types of
damage, follow these suggestions:

 Use only a power source and connection appropriate for this
projector as indicated on the marking label.

 Do not overload an electrical outlet, power strip, or convenience
receptacle. The overall system load must not exceed 80 percent
of the branch circuit rating. If an extension cord or power strip is
used, make sure that the cord or strip is rated for the product and
that the total ampere ratings of all products plugged into the
extension cord or power strip do not exceed 80 percent of the
extension cord or strip ampere ratings limit.

 Install the projector near an outlet that you can easily reach.
Disconnect the product by grasping the plug firmly and pulling it
from the outlet. Never disconnect it by pulling the cord.

 Unplug the projector from the wall outlet before cleaning. Do not
use liquid cleaners or aerosol cleaners.

 Slots and openings in the cabinet are provided for ventilation.
These openings must not be blocked or covered. Never push
objects of any kind into cabinet slots or other openings.

 Do not drop the projector or place it on an unstable surface.

 Do not expose this product to rain or moisture.

 Do not allow anything to rest on the power cord. Do not walk on
the cord.

 Do not allow the projector to be exposed to high temperatures.

 Do not open the projector or attempt to service this product for
any other reason than to replace the lamp module. Adjust only
those controls that are covered by the operating instructions. If
the projector is not operating properly or has been dropped or
damaged, contact your Compaq authorized dealer, reseller, or
service provider.
Cleaning the Lens
To minimize the risk of damaging or scratching the lens surface,
this cleaning procedure has been developed. The first
recommendation is to remove any dust particles from the lens by
blowing them off with clean, dry, deionized air. However, this may
not be a convenient method, and an alternate method is described
below.
To clean the lens, use only a clean cloth and follow these steps:
CAUTION:  Do not spray any type of fluid or cleaner
directly on the lens surface. Do not use liquid cleaners.
1. Wipe the lens in a single direction with a clean, dry cloth. Do
not wipe back and forth across the lens surface.
2. If the cloth is dirty or smears the lens, wash the cloth. If the
cloth is still dirty after washing it or the fabric is damaged,
replace it.
✎Do not use fabric softener when washing a cleaning cloth
or softener sheets when drying the cloth.

CAUTION:  Do not store a cleaning cloth in contact
with the lens for a long time as doing so may
contaminate the lens with dye from the cloth. The cloth
can be contaminated if left in the open air.
Replacing the Projector Lamp Module
!WARNING:  When the lamp reaches its end of life, it
may pop or rupture. To reduce the risk of personal
injury, be careful when removing the lamp cover as
broken glass may be present. Never open the lamp cover
while the projector is operating or when the lamp is hot.
The projector will alert you when the lamp approaches its failure
mode or end of life. When the message “Lamp May Fail Soon -
Replacement Suggested” displays on the projection screen, you
should change the lamp as soon as possible. Contact your local
Compaq authorized dealer, seller, or reseller to purchase a spare
lamp or have the lamp changed. You can also purchase a lamp
directly through 
www.compaq.com.
