To mount the projector on a tripod
The projector includes standard tripod mount on the bottom of the projector. This 
allows the projector to be mounted on tripods readily available at camera and other 
electronic stores. 
ÄCAUTION: 
■The tripod should be capable of supporting a weight of at least 5 lb. Refer to the 
owner’s manual that came with your tripod for more information.
■Do not overtighten the tripod mount screw. Doing so could strip the screw and 
cause the projector to fall off the tripod. 
1. If necessary, remove the tripod mounting block from the tripod. 
2. If there is a guide pin on the tripod mounting block, align it with the guide pin 
hole on the bottom of the projector.

To install on the ceiling
ÅWARN I N G: To minimize the risk of injury from improperly installed equipment, it 
is recommended that a professional installer performs the ceiling installation.
1. Align the end of the ceiling-mount bracket with the center hole in the lower-mount 
bracket, and firmly secure it with a washer and bolt.
2. Attach the mounting bracket to the projector. See the instructions that came with 
the ceiling mount.

a slip knot around the stationary object, and be sure it cannot slip off.

Fixing Problems
Start-up problems
If no lights or sounds turn on:
❏Be sure that the power cable is securely connected to the 
projector and the other end is plugged into an outlet with power.
❏Press the power button again.
If nothing is projected but the projector seems to start up:
❏Be sure the lens cap has been removed.
❏Check the front of the projector—the latch for the lamp module 
should be down.
❏If the lamp indicator is on, replace or reinstall the lamp module. If 
the lamp indicator is blinking, turn off the projector and allow it 
to cool before restarting it—replace the lamp module if the 
indicator continues to blink.
❏If the temperature indicator is on or blinking, turn off the 
projector and allow it to cool before restarting it. If the warning 
light turns on or blinks again, contact HP for assistance.
If the projector makes a “ticking” sound, if the projector lamp does not turn on, 
and if the lamp indicator is on or blinking: 
❏The projector lamp is too hot to light. Turn the projector off and 
wait for it to cool before turning it on again.
❏The projector lamp is not making a good connection. Turn off the 
projector and allow it to cool. Then, on the front of the projector, 
slide the latch for the lamp module up and down. Be sure it is all 
the way down.
❏The projector lamp has reached the end of its life. Replace the 
lamp.
