If a lamp fails or if a replacement message appears on the screen, a qualified person can replace the projector
lamp. Do not access the service panel without a replacement lamp and instructions in hand.
WARNING • If the projector is mounted on the boom, the manufacturer recommends contacting
your authorized SMART reseller when the lamp must be exchanged.
• Only qualified personnel should replace the projector lamp. Replacing the lamp
in a boom-mounted projector might result in fall and injury.
• If you continue to use the projector after the replacement message appears, the lamp
might shatter or burst, scattering glass throughout the projector head. Only qualified
personnel should replace the projector lamp. Replacing the lamp in a boom-mounted

• If the lamp has shattered or burst, do not touch the glass fragments because they might
cause injury. Leave and then ventilate the area where the lamp shattered or burst.
Wash your hands thoroughly if you have come into contact with lamp debris.
Thoroughly clean the area around the projector, and discard any edible items placed in that
area because they might be contaminated.

damage or personal injury from falling pieces of glass if the lamp is broken.

the old lamp assembly.
• Wear protective eyewear while changing the lamp. Failure to do so can cause injury or loss
of eyesight if the lamp shatters or bursts.
