Solution
f Wait approximately 5
minutes (PT-DZ16K2:
up to 20 minutes) in the
current status.

.
f Remove any objects that are blocking the air intake/
exhaust port.
f Install the projector in a location with the operating
environment temperature between 0 °C (32 °F) and
45 °C (113 °F)

, and ambient humidity between 20 %
and 80 % (no condensation).
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 181)
f Turn the <MAIN POWER>
switch to <OFF>
(x page 64), and
consult your dealer.
*1 When using the projector at high altitudes (between 1 400 m (4 593') and 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 it at elevations lower than 1 400 m (4 593') above sea level, and should be between 0 °C (32 °F) and 35 °C (95 °F) when
using it at high altitudes (between 1 400 m (4 593') and 2 700 m (8 858') above sea level). If you use the Replacement lamp unit (for portrait mode)
together with the smoke cut lter, the operating environment temperature should be between 0 °C (32 °F) and 30 °C (86 °F). (Only for PT-DZ21K2,
PT-DS20K2, PT-DW17K2)
Note
f If the temperature indicator <TEMP> is still lit or blinking after taking the measures, ask your dealer for repair.
Filter indicator <FILTER>
