.
f Remove any objects that are blocking the air intake/
exhaust port.
f Install the projector in a location with an ambient
temperature of 0 °C (32 °F) to 45 °C (113 °F)

.
f Do not use the projector at high altitudes of 2 700 m
(8 858') or higher above sea level.
f Clean or replace the air lter unit. (x page 157)
f Turn the <MAIN POWER>
switch to <OFF>
(x page 55), and
consult your dealer.
*1 When using the projector at high altitudes (1 400 m (4 593') or higher – lower than 2 700 m (8 858') above sea level), the operating environment
temperature should be between 0 °C (32 °F) and 40 °C (104 °F).
If you use the Smoke cut lter, the operating environment temperature should be between 0 °C (32 °F) and 35 °C (95 °F). However, it cannot be
used at high altitudes.
If you use the Replacement lamp unit (for portrait mode), the operating environment temperature should be between 0 °C (32 °F) and 40 °C
(104 °F) when using the projector at elevations lower than 1 400 m (4 593') above sea level, and between 0 °C (32 °F) and 35 °C (95 °F) when
using the projector at high altitudes. If you use the Smoke cut lter together, the operating environment temperature should be between 0 °C (32 °F)
and 30 °C (86 °F).
Note
f If the temperature indicator <TEMP> is still lit or ashing after taking the preceding measures, ask your dealer for repair.
f If you use the projector with the following two settings made, the light output may drop by approx. 20 % to protect the projector when an
ambient temperature becomes 40 °C (104 °F) or higher (35 °C (95 °F) or higher if [HIGH ALTITUDE MODE] is set to [ON], or if the Smoke
cut lter is used).

Status
The lter is clogged.
The temperature inside or outside the projector is abnormally high.
The air lter unit is not
attached.
Cause f Is the air lter unit dirty?
f Is the air intake/exhaust
port blocked?
f Is [HIGH ALTITUDE
MODE] set correctly?
f Is the air lter unit
attached?
Solution
f Clean or replace the air
lter unit. (x page 157)
f Remove any objects that
are blocking the air intake/
exhaust port.
f When using the projector
at high altitudes between
1 400 m (4 593') or higher
and lower than 2 700 m
(8 858') above sea level,
set [HIGH ALTITUDE
MODE] (x page 109) to
[ON].
f Do not use the projector
at high altitudes of
2 700 m (8 858') or higher
above sea level.
f Attach the air lter unit.
Note
f If the lter indicator <FILTER> is still lit or ashing after taking the preceding measures, ask your dealer for repair.
f If the lter is clogged, only one lamp may light even when [LAMP SELECT] is set to [DUAL]. By cleaning the air lter unit or replacing it with
a new one, the lamp will light properly.
