cause burns, as well as damage to the lamp.
nNever unscrew anything except the appointed (marked by an arrow) screws.
nDo not open the lamp cover while the projector is mounted on a wall or ceiling. This
is dangerous, since if the lamp’s bulb has broken, glass shards will fall out when the
cover is opened. Working in high places is dangerous, so askTeq to have the lamp
replaced, even if the bulb is not broken.
nDo not use the projector with the lamp cover removed. At the lamp replacing, make sure
that the screws are screwed in rmly. Loose screws could result in damage or injury.
nOnly use the lamp of the specied type. Use of a lamp that does not meet the lamp
specications for this model may cause a re, damage or shorten the life of this product.
nIf the lamp breaks soon after the rst time it is used, it is possible that there are
electrical problems. If this happens, consult Teq.
nHandle with care: jolting or scratching could cause the lamp bulb to burst during use.
nUsing the lamp for long periods of time, may cause it to darken, burn out or burst.
When the pictures appear dark or when the color tone is poor, please replace the lamp
as soon as possible. Do not use old (used) lamps; this is a cause of breakage.
