Notes on Installation and Usage
Subject to direct cool or warm air
from an air-conditioner
Installing in such a location may cause
malfunction of the unit due to moisture
condensation or rise in temperature.
Near a heat or smoke sensor
Malfunction of the sensor may be caused.
Very dusty, extremely smoky
Avoid installing the unit in a very dusty or
extremely smoky environment. Otherwise,
the air filter will become obstructed, and this
may cause a malfunction of the unit or
damage it. Dust preventing the air passing
through the filter may cause a rise in the
internal temperature of the unit. Clean the air
filter whenever you replace the lamp.
When using the unit at an altitude of 1,500 m
or higher, set the “High Altitude Mode” to
“On” in the Setup menu. Failing to set this
mode when using the unit at high altitudes
could have adverse effects, such as reducing
the reliability of certain components.
Note on the screen
When using a screen with an uneven surface,
stripes pattern may rarely appear on the
screen depending on the distance between
the screen and the unit or the zooming
magnifications. This is not a malfunction of
the unit.
Do not use the unit under the following
conditions.
Do not topple the unit
Avoid using as the unit topples over on its
side. It may cause malfunction.
Do not tilt right/left
Avoid using as the unit tilts more than 20
degrees. Do not install the unit other than on
the floor or ceiling. These installations may
cause malfunction.
Do not block the ventilation holes
Avoid using something to cover over the
ventilation holes (exhaust/intake);
otherwise, the 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 on the
Remote Commander to cut off the picture.
