If the screen doesn't stay up when raised,
increase the lift strength by turning the angle
key right.

lowered, decrease the lift strength by turning
the angle key left.
Tilt (Flex arm)
According to personal preference, the screen
of the EasyViewer/Quartz can be tilt. To do
this, make sure you take hold of the screen on
both the left and right side of the screen.
Increase Friction
If the screen tilts down, then you'll need to increase
friction by turning the angle key right.
Decrease Friction
If the screen is too difficult to tilt, then you'll need to
decrease friction by turning the angle key left.

USAGE TIPS

Reading
Reading is best done in positive or negative mode. These modes adapt the image for the visually
impaired to a high-contrast image with improved background. Background and letters can be set at
your discretion. The background can be set by means of background suppression (Quartz). This
will allow you to filter out the structure of a sheet. This unique KOBA Vision function allows you at
all times to set a high contrast background without annoying paper impurities. A newspaper can be
read without annoying paper impurities. Factory settings will take you back to the original settings.
Watch photos
Photos are best watched in photo mode. This mode is a unprocessed image without contrast
enhancement. By changing the brightness (Quartz), you can adjust the image so that the photo
becomes clearly visible.
Crafting
Crafting is best done with a small magnification. It is better to select a dark background during this
activity so that the camera is not hindered by large differences in contrast with whatever is
darkened by the hands.
