Precautions For Use - Canon 4K501ST Manual

7. Precautions For Use

● Do not look into the projection lens while it is projecting.
The projector emits very bright light, which may damage your vision.
● Do not place objects in front of the lens while projecting.
Objects may heat up and burn if exposed to the concentrated light of the projector for long periods.
● Do not block the vent (intake air & exhaust) while the projector is running.
Allowing heat to build up inside the unit may lead to malfunctions or risk of fire.
● Replace the lamp as soon as possible if the lamp burns out or if the replacement time is
reached.
The projector uses a high-pressure mercury lamp as its light source. This lamp degrades over time and
becomes dimmer as it is used. Furthermore, the possibility of the lamp bursting as it is used is extremely high.
If the lamp should burst, return the projector to your local service center to have the lamp replaced and the
unit inspected.
**There is a less than half probability of the lamp bursting before the lamp replacement time is reached. Normally it is most likely that
the lamp will not burst before the replacement time. Even if the lamp does burst, the number of hours the lamp can be used before that
happens varies depending on each lamp. Although extremely minute flaws that may occur during production have been suspected as
the cause of the individual differences in the hours of use before a lamp bursts, there is no way to predict this period with accuracy.
● In highlands(*1) with low atmospheric pressure, use with the following setting(*2)
To prevent internal overheat, set the Fan mode function "High-Altitude".
