Notes on Installation and Usage
Do not block the ventilation holes
Avoid using a thick-piled carpet or anything
that covers the ventilation holes (exhaust/
intake); otherwise, internal heat may build
up.
Do not place a blocking object just
in front of the lens
Do not place any object just in front of the
lens that may block the light during
projection. Heat from the light may damage
the object. Use the PIC MUTING key to cut
off the picture.
Do not use the Security bar for
transporting or installation
Use the Security bar at the rear of the
projector for a purpose of preventing theft,
by attaching a commercially available theft
prevention cable for example. If you lift the
projector by holding the Security bar, or
hang the projector by using this bar, it may
cause the projector to fall or be damaged.
When using the projector at an altitude of
1,500 m or higher, turn on “High
Altitude Mode” in the INSTALL SETTING
menu. Failing to set this mode when using
the projector at high altitudes could have
adverse effects, such as reducing
the reliability of certain components.
Note on carrying the projector
The unit is manufactured using high-
precision technology. When transporting the
unit stored in the carrying case, do not drop
the unit or subject it to shock, as this may
cause damage. When storing the unit in the
carrying case, disconnect the AC power cord
and all other connecting cables or cards, and
store the supplied accessories in a pocket of
the carrying case.
Note on the screen
When using a screen with an uneven surface,
a striped pattern may rarely appear on the
screen depending on the distance between
the screen and the projector or the zooming
magnification settings used. This is not a
malfunction of the projector.
