Note •If the ball joints become loose after adjusting
the position of the head display, turn the dials
on either end of the flexible arm clockwise to
fix the head display in place.
•If you cannot see the full image after adjusting
the flexible arm, you may have to adjust the
position of the head band to bring the display
into your field of view.
Adjust the position of the display to fit your
application
Depending on your activity, you can position the head
display so that the image takes up the whole field of
vision, or you can keep it in your peripheral vision to
keep both eyes on your work. Follow these tips to
ensure that you can see the whole image:
• To keep the image in your field of view
at all times, position the head display
right in front of your eye and make sure
that the lens is facing towards the eye.
• To keep the image in your peripheral
vision (so that it is only seen when you
move your eyes in that direction),
position the head display at the edge of
your field of view and make sure that
the lens is facing your eye. If the entire
image is not visible, change the angle
of the head display or switch to Reduce mode.

Adjusting the display

Turn the focus adjustment dial to
either side until the image on the
head display is in focus. The focal
length of the optics can be changed
from 30 cm to infinity.

the brightness of the image on the head display. There

To prevent unintentional operation, activate the key lock
function by pressing the mode button and the image
rotation button on the control panel simultaneously.
