Getting the projector status
To get the projector status:
SPress the  enter button on the projector or remote control and go to  Help. 
This screen shows information and status for the projector.
Cleaning the projector lens
You can clean the front lens of the projector using the following recommendations. You cannot 
clean any of the internal surfaces.
 To minimize the risk of damaging or scratching  the lens surface, blow dust particles off the 
lens with clean, dry, deionized air.
 If this method does not work, use the following method:
a.Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and forth 
across the lens.
b. 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.
CAUTION: Cleaning requires special consideration:
 Do not spray any type of fluid or cleaner directly on the lens surface. Cleaners might 
damage the lens.
 Do not use fabric softener when washing a cleaning cloth or softener sheets when drying 
the cloth. Chemicals on the cloth might damage the surface of the lens. 
 Do not store a cleaning cloth in contact with  the lens for a long time because doing so 
contaminates the lens with dye from the cloth. The cloth can be contaminated if left in the 
open air. 
						

							
Maintaining the Projector

Replacing the lamp module
As the projector operates over time, the brightness of the projector lamp gradually decreases 
and the lamp becomes more susceptible to breakage. You can install a new lamp at any time 
to bring the projector up to factory-fresh brightness. We recommend replacing the lamp if a 
warning message is displayed.
WARN I NG! Replacing the lamp module requires special consideration:
 To reduce the risk of injury, be careful when removing the lamp module as broken glass 
might be present. For a ceiling installation,  wear goggles and gloves when removing the 
lamp module. If the lamp is broken, contact HP about repairs that might be required due to 
glass fragments. 
 The lamp contains a small amount of mercury. If the lamp breaks, adequately ventilate the 
area where the breakage occurred. Disposal of this lamp might be regulated due to 
environmental considerations. For disposal or recycling information, contact your local 
authorities or the Electronic Industries Alliance at http://www.eiae.org.
 Because the lamp assembly operates at a very high temperature, wait 30 minutes before 
removing the lamp module.
1. Turn off the projector and allow it to cool for 30 minutes.
2. Unplug the power cord.
3. Press the release latch 
1 on the lamp cover and remove the cover 2.
4. Press the release latch on the lamp connector and unplug the connector 
3.

7. Plug in the lamp connector.
8. Snap the lamp cover into place.
9. Turn on the projector. If the lamp does not turn on after the warm-up period, try reinstalling 
the lamp.
10. Press  enter, go to  Setup > Advanced setup > Reset lamp hours,  and press enter.

Upgrading the projector 47
Upgrading the projector
Updating the firmware
HP might periodically release updated versions of the projector firmware to enhance the 
projector performance. The projector firmware version is shown in the on-screen menu at Help. 
Check for updated versions at http://www.hp.com/go/proj_firmware.
USB method
1. On a computer with a USB port, go to the HP  projector upgrade website (see introduction 
for this section) and download the latest file intended for a USB upgrade.
2. Connect a USB cable (available from HP) between the USB port on the projector and the 
USB port on the computer.
3. On the computer, run the file you downloaded by double-clicking the file. Follow the on-

Installing the projector
Choosing cables
If you are permanently installing the projector or using it with long cables, consider the 
following suggestions when planning the installation:
 Use high-quality cables. Use only video cables  that are made with 75-ohm coaxial cable 
and connectors. For high-resolution video, use low-loss video cables. For standard audio, 
use audio cables that are shielded. For digital audio, use 75-ohm coaxial cables.
 Minimize cable length as much as possible. For video cables longer than 6 m (20 ft), use 
low-loss coaxial cables. For standard audio cables longer than 6 m (20 ft), use 12-gauge 
wire.
 Do not run audio or video cables next to power or network cables. If they must cross, cross 
them at 90 degrees.
 If you are installing cables in walls, use  cables with necessary approvals, such as 
Underwriters Laboratories (UL) approval.
 If you are running cables above a dropped ceiling, you must use plenum-rated cables if the 
space above the ceiling is open to the space above other rooms. You must use plenum-
rated cables if you are running cables in a duct.
 Before installing cables permanently, check the setup with the final cables in the open.
Installing on a table
This installation is covered in detail in Chapte r 1. See “Setting up the projector” on page 16 
for more information.
Installing on the ceiling
WARN I NG! To minimize the risk of injury from improperly installed equipment, it is 
recommended that a professional installer performs the ceiling installation. 
						

							
Installing Permanently
50
1. Attach the projector to the ceiling using an HP  ceiling mount kit. Refer to the installation 
instructions provided with the ceiling mount kit.
2. After the projector is mounted on the ceiling, adjust the projector settings to match this 
setup. Press  enter, go to  Setup > Advanced setup > Projector position,  and select  Front 
Ceiling.
Installing for rear projection
1. Place the projector 1 to 10 m (3 to 33 ft) behind a translucent screen that is designed for 
rear projection.
See “Setting up the projector” on page 16 or “Installing on the ceiling” on page 49 for 
more instructions.
2. Press  enter, go to  Setup > Advanced setup > Projector position.  Then select  Rear Table or  
Rear Ceiling.
Locking the projector
The projector includes a built in slot to secure the projector with a cable and lock (such as the 
Kensington MicroSaver lock system, available at many computer stores). 
1. Wrap the cable around a secure object, such as  a table leg. Loop the cable to create a slip 
knot around the stationary object, and be sure it cannot slip off.
2. Insert the lock 
1 into the hole and twist the key 2.
