When wearing eyeglasses
Use the eye shades in the normal, folded-down position. This will
prevent the eyeglasses from being scratched.
When not wearing eyeglasses
Extend the folded eye shades in the direction of the arrow to
prevent extraneous light from entering between the eyepieces and
eyes.
When the WHN10X-H eyepieces are used, an eyepiece micrometer
disk can be mounted.
Use 24 mm dia. x 1.5 mm thick micrometer disks.
Turn the built-in micrometer-mounting frame
a
to the arrow direc-
tion (see figure) to remove it from the eyepiece and place a microm-
eter disk
b
into the mounting frame so that the surface with the
model indication faces downward.
} The micrometer-mounting frame may be to tight for certain microm-
eter disks.
In this case, turn the frame by holding the circumference with a
light, uniform force or by applying the frame against a rubber sheet.
Do not grasp the frame with a strong force, as this may deform the
frame and make it harder to remove it.
Re-attach the micrometer mounting frame in the original position.
} Be careful not to touch the lens or micrometer surface with your
finger.
Slide the light path selector knob to select the desired light path.

} Adjust the height and tilt of the eyepieces to obtain the most com-
fortable viewing position.
Holding the binocular section with both hands, adjust it to the
desired position.
Never attempt to force the binocular section past the upper or
lower stop position. Applying excessive force could destroy the
limiting mechanism.
