5. 3. 3. Notes on the replacement of the lamp unit
1. Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Handle with care.
2. When replacing the lamp unit, be sure to hold it by the handle because its surface is pointed and its shape is protruded.
3. When the projector is mounted on the ceiling, do not conduct work while your face is near the lamp unit.
4. Do not remove or loosen the screws other than specified ones when replacing the lamp unit.
5. Use same type of lamp unit for both lamps.
6. When replacing the lamp unit, loosen the rear cover fixing screw while putting your hand on.
Note
・When you replace the lamp unit with new one, the projector resets the runtime of the lamp unit automatically.
5. 3. 4. Replacement procedure for lamp unit
1. Power off the projector and disconnect the power plug from the power outlet.
And wait at least one hour, and then check if the lamp unit has been cooled down.
2. Loosen the lamp unit cover fixing screw (one screw) until it turns freely, and then open the lamp unit cover
in the direction of the arrow.
①Open a little
②Slide it in the direction of the arrow, and then pull it out
backward to remove.
Caution
・If you loosen the rear cover fixing screw with the projector
・If you loosen the rear cover fixing screw with the projector
installed upward in the vertical direction, the rear cover may
open on its weight and may be dropped off.
3. Loosen the lamp case fixing screws (two screws each) until they turns freely, and then hold the lamp case
handles, pull out backward.
4. Install the Lamp units and reverse the disassembly procedures, install the rear cover.
* Projector does not turn on by protection circuit, if lamp unit or rear cover are incompletely-installed.
* If the lamp unit is not installed properly, remove it and then push it in slowly. Pushing it in quickly or forcibly may break the connector.

5. 3. 5. Air filter maintenance
1. Air filter is clogged by dust, and if the replacement message is displayed on the screen, filter indicator <FILTER> has
a red light. In this case perform the maintenance.
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. The cleaning and replacement cycle of the air filter unit varies depending on the usage environment.
If dirt does not come off even after the unit is maintained, it is time for the unit to be replaced.
5. 3. 6. 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.
3. Pull out the air filter unit frame from the tabs of the projector body while slightly pressing around the center of
the frame at the front side (with the lens) inward as described with the arrow, and pull out the frame at the opposite
side from the tabs to remove the air filter unit.
4. Wash 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.
* Do not dry using drying devices such as dryers.
* Dry it thoroughly before attaching it back to the projector.
(Please read the page "Maintenance/Replacement" on the instruction book to know about details.)
5. 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.
5. 4. Initialization for control device password
To revert to the factory default password (AAAA), perform the following operations while the screen asking
for a control device password input is displayed.
1. Press the <AUTO SETUP> button on the remote control or control panel for at least two seconds.
2. Press ▼ for at least two seconds.

5. 5. Portrait Mode
When using the projector in the portrait mode (projection of vertically long images).
1. Install the optional Replacement lamp unit (for portrait mode) to the projector.
2. The [MAIN VERSION] of firmware of the projector has to be [2.00] or later version.
When the main version of firmware is lower than [2.00], please be firmware version up.
3. Install the projector with the terminals surface facing down.
Note
・When used in portrait mode, can not "High" to lamp power setting.
・The estimated duration before replacing the Replacement lamp unit (for portrait mode) is 500 hours.
・The estimated duration before replacing the Replacement lamp unit (for portrait mode) is 500 hours.
