Usage at High Altitude
When using the projector at an altitude of
1,500 m or higher, turn on "High Altitude
Mode" in the Installation 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.
