5. 3. 3. Air filter maintenance
1. The air filter is clogged with dust, causing the filter replacement message to appear on the screen and
the filter indicator <FILTER> to light in red. In such a case, clean the air filter unit.
2. The proceeds of the air filter clogging, becomes hot of projector inside, and <TEMP>indicator is lit , power shut down.
Then <FILTER>Indicator remains red , <TEMP> indicator will flash (twice) red.
3. Indication of cleaning is 10,000 hours. but varies greatly depending on the usage environment.
If dirt does not come off even if the unit is maintained, it is time for the unit to be replaced.

5. 3. 4. Cleaning procedure for Air filter unit
1. Make sure to turn off the power before replacing the air filter unit.
2. Loosen the lamp unit cover fixing screw (one screw) until it turns freely, then remove the Air filter cover,
pull out the air filter unit.

pull out the air filter unit.
3. Clean and dry the air filter unit.
1) Soak the air filter unit in cold or warm water and then lightly rinse it.
* Do not use cleaning tools such as brushes.
2) Rinse the unit two to three times using fresh water each time.
3) Let the unit naturally dry off in a well-ventilated place where there is
little dust and the unit is protected from direct sunlight.

* Make sure that it is sufficiently dry before reinstalling it to the projector.
* Do not dry using drying devices such as dryers.
* Do not dry using drying devices such as dryers.
(Please read the page "Maintenance/Replacement" on the instruction book to know about details.)
4. After cleaning the air filter unit, install the filter unit and the air filter cover.
* The air filter unit has no difference between top and bottom, but is two-sided.
* Match the protrusion position of the air filter with the grooves on the projector body.
* Match the protrusion position of the air filter with the grooves on the projector body.

5. 5. Portrait mode
When using the projector in the portrait mode (projection of vertically long images).
1. The [MAIN VERSION] of the projector firmware must be [2.00] or higher version.
2. Install the optional replacement lamp unit for portrait mode exclusive use to the projector.
2. Install the optional replacement lamp unit for portrait mode exclusive use to the projector.
3. Install it with the terminals surface facing down.
Do not use the projector tilted to the right and left, front and back.
Using the projector at an angle that exceeds 15° in either direction may reduce product life or result in malfunction.
Using the projector at an angle that exceeds 15° in either direction may reduce product life or result in malfunction.
4. The guide for replacing the portrait mode exclusive use lamp is 500 hours.
The on-screen message for replacing the lamp appears after 300 hours.

[ Note ]
・
Using the portrait mode exclusive use lamp will set the cooling condition to [PORTRAIT SETTING].
・
During portrait setting, the on-screen menu will be displayed horizontally.
・
When using the portrait mode lamp unit, the operating environment temperature will be 0°C (32°F) to 40°C (104°F);
when using it at high altitudes 1 400 m (4 593 ft) – 2 700 m (8 858 ft) from sea level, the operating environment
temperature will be 0°C (32°F) to 35°C (95°F); when using it with a smoke cut filter, the operating environment
temperature will be 0°C (32°F) to 30°C (86°F).
