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 Installation 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.
