7. PRECAUTIONS FOR USE
●
Do not unplug the projector after turning off the lamp until the cooling fan stops.
Not allowing the projector to cool sufficiently may damage the unit.
* The hot lamp will cause burns. Wait at least 45 minutes after the fan stops before
replacing the lamp.
●
Always use the LV-CL08 ceiling attachment when mounting the projector to a ceiling.
The projector may fall or be damaged if mounted with a mounting bracket intended
for a different model.
●
Do not look directly at the projection lens when it is in operation.
The projection is very bright and can damage eyesight.
●
Replace the lamp with a new lamp promptly when lamp replacement is indicated.
A high-pressure mercury lamp is used as the projector's light source. Due to the
characteristics of the mercury lamp, it may burst because of deterioration over long
use.
Should the lamp burst, we recommend that you return the projector to the store
where you purchased it to have the lamp replaced and the unit inspected.
●
Do not use the projector when tilted excessively.
Place the projector on surfaces with a horizontal slant of no more than ±20 degrees.
Due to the characteristics of the mercury lamp, using the projector at an excessive
inclination may cause the lamp to operate abnormally or shorten its service life.
The projector was not designed to be used while tilted; therefore, use the projector on
a level surface whenever possible.
