Caution
Pay attention to the following points when carrying or transporting the projector.
■
This projector is a precision instrument. Do not knock it over or subject it to impacts. Doing so
may cause a malfunction.
■
When carrying or holding up the projector after attaching the lens unit, be sure not to hold the
lens. Doing so may cause damage to the lens unit.
■
Do not reuse any packaging or shock-absorbent materials that were supplied with the projector
at the time of purchase for transporting or shipping the projector. Protection of the projector
cannot be guaranteed if used packaging or shock-absorbent materials are reused. Fragments
from shock-absorbent material may also enter the interior of the projector which could cause a
malfunction.
■
If transportation is necessary, the lens unit should be removed before transporting the projector.
If the projector is subjected to excessive impacts during transportation, the lens unit may be
damaged. Removal and installation of the lens unit should not be performed by the user. Be
sure to have the procedure performed by a qualified technician or contact the Canon Customer
Support Center.
■
Disconnect the cables connected to the projector. Carrying the projector while the cables are
attached may cause an accident.
■
Retract the adjustable feet before moving the projector. Leaving the feet extended may cause
damage.
Caution
Pay attention to the following points when installing or using the projector.
■
Do not touch the lens with bare hands. Doing so may result in deterioration of image quality.
■
If the projector is abruptly taken from a cool to a warm location, condensation may form on the
lens or mirrors, which may cause a blurred image. Wait until the condensation has evaporated
for the image projected to return to normal.
■
Do not install the projector in a location where the temperature is high or low. Doing so may
cause a malfunction. For guidelines on operating temperatures, see “Product Specifications”.
■
Do not place any objects on top of the projector that may change shape or color due to heat.
■
Projector settings must be adjusted when using the projector at high altitudes or in upward or
downward projection. Failure to adjust the settings may shorten the lamp life or damage the
lamp. For details, contact the Canon Customer Support Center.
■
Do not install the projector near high-voltage electrical power lines or an electrical power source.
■
Do not use the projector on a soft surface such as carpet or sponge mat, etc. Doing so could
cause heat to build up inside the projector and this could result in a malfunction.
■
Do not block the air intake or exhaust vents of the cooling fan. If the air intake or exhaust vent is
blocked, heat cannot be released from inside the projector, which may shorten the useful life of
the lamp or cause malfunction.
■
Installing the projector in the wrong direction may cause a malfunction or accident. Do not install
the projector with one side raised, or with the projector tilted toward the left or right.
■
Install the projector with sufficient space between air intakes and exhaust vents and walls.
Failure to do so could cause a malfunction.
■
Do not install the projector in a location that is damp, or where there is a lot of dust, oily smoke
or tobacco smoke. Doing so could cause contamination of optical components such as the lens
and the mirror and may result in deterioration of image quality.
