3.6 Maintenance
Cleaning
The outside of the viewer can be cleaned with regular cleaning liquids, not too
aggressive or polishing. The lenses are not water tight. Clean the lenses with a soft
cloth.
Dust visible on the LCD
Turn on the viewer to see the dust particles.
Take the lens barrels out of the front of the viewer.
You can blow with compressed cleaned (oil free) air, not higher than 2 bars, inside
the housing of the viewer towards the LCD. Not too deep and avoid touching the
sides to prevent scratches on the inside walls.
You can use a brush or soft cloth to wipe resistant particles away. There is no glass
cover on the LCD! Do not apply too much pressure / force on it.
When re- assembling the lens barrels in the front, it might happen new particles drop
on the LCD. You can repeat the above steps until the result is satisfying.
Miss alignment of the image splitter.
Between the left and right image on the LCD runs a thin metal plate from the LCD to
your nose / between the eyes. This avoids the left or right eye to see parts of the
image of the other side. The position of this splitter is accurate but might be, for some
reason be out of alignment, you might see a very small piece of image of the other
side (left or right).
To resolve do the following:
For whatever source you have, we supply a test image that looks like this:
- Set your source to show the above image in the viewer.
- Look through the lenses and see the direction and amount of miss alignment
of the splitter (metal plate).
- Now unscrew both lenses out of the housing. Be sure the hexagon screws at
the side of the lenses are unlocked.
- With your fingers you can push the splitter (through the lens holes) to the left
or right to get the splitter aligned. You actually bend the plate a little.
- Check with the lenses if the alignment is right or repeat the previous step.
- Clean the interior of the viewer with low pressure compressed air.
- Re-assemble the lens barrels to the viewer and the alignment is finished.
