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 filter, 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 filter 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 flashing 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 filter is used).

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 filter unit.
Note
f
If the filter indicator <FILTER> is still lit or flashing after taking the preceding measures, ask your dealer for repair.
f
If the filter is clogged, only one lamp may light even when [LAMP SELECT] is set to [DUAL]. By cleaning the air filter unit or replacing it with
a new one, the lamp will light properly.
