For the customers in the Netherlands
Voor de klanten in Nederland
Hoe u de batterijen moet verwijderen, leest u in de tekst
van deze handleiding.
Gooi de batterij niet weg maar lever deze in als klein
chemisch afval (KCA).
Für Kunden in Deutschland
Entsorgungshinweis: Bitte werfen Sie nur entladene
Batterien in die Sammelboxen beim Handel oder den
Kommunen. Entladen sind Batterien in der Regel dann,
wenn das Gerät abschaltet und signalisiert “Batterie
leer” oder nach längerer Gebrauchsdauer der Batterien
“nicht mehr einwandfrei funktioniert”. Um
sicherzugehen, kleben Sie die Batteriepole z.B. mit
einem Klebestreifen ab oder geben Sie die Batterien
einzeln in einen Plastikbeutel.

similarly.
(02 VCOM R, 03 VCOM B)
4. Select the SAVE TO MEMORY on the Device adjust
page of the menu. Press the ENTER to save the data.
2-5-2. Polarization Plate Adjustment
Press the “PIC MUTE” button and the whole screen will
become black. In this state, adjust the respective polarization plate until the black becomes the darkest.
2-5-3. 3D GAMMA Adjustment (Outline)
The principle of 3D GAMMA is described before the adjustment
of 3D GAMMA.
3D GAMMA is like a function which can individually adjust W/
B at a total of 180 points brightness 8 levels, horizontal direction
7 points, vertical direction 4 points (8*7*4=224 points).
2-5-4. 3D GAMMA Adjustments
1. First input “GAMMA.”
2. Set LEVEL to 1.
3. Study the uniformity of the whole screen, and locate
the areas where uniformity is poor.
4. Changing “POSITION” to 1, 2, or 3 will display the
cursor. The position of the cursor is the position which
will be adjusted.
Move the cursor to the area with poor uniformity.
5. Move “R” and “B” up and down, and adjust so that the
uniformity is the same as the other areas.
6. Set LEVEL 2.
7. Like steps 3, 4, and 5, adjust the areas with poor
uniformity.
8. Adjust up to LEVEL 6.
9. Study the test pattern from LEVEL 1 to LEVEL 6, and
if no problems, return to the first hierarchy, adjust the
device, and save the data in SAVE TO MEMORY.
Precautions:
1. Basically adjust RED and BLUE only without changing GREEN.
2. Do not adjust LEVEL 7.
3. To set back factory settings should adjustments fail,
skip “SAVE TO MEMORY,” and turn off the power.
All the adjusted data will be set back to factory
settings.
Factory settings cannot be set back however if “SAVE
TO MEMORY” has already been implemented. So
check the picture quality carefully prior to implementing “SAVE TO MEMORY.”

4. For zoom lens, the uniformity will change slightly
according to the zoom position.
As uniformity will change slightly according to the F
number of the lens, perform the adjustments on the
projection system under the normal using conditions.
5. Do not change other items in the Device Adjust Menu.
The device adjust menu contains important parameters
for machine operations.
Unnecessary operations will result in “no image” and
“abnormal image.”
“Factory reset” cannot be performed on device adjust
menu items.
(Implementing SAVE TO MEMORY will completely
overwrite the data.)
Do not change data unnecessarily.
