improper use ignoring the contents
described herein may negatively
affect product performance and
functionality.
WARNING
This indication alerts you to the
fact that any improper use ignoring
the contents described herein can
result in potential death or serious
injury.
CAUTION
This indication alerts you to the
fact that any improper use ignoring
the contents described herein can

• Do not look through the binoculars
while walking. You may walk into
something and get hurt. (Fig. 2)
• Do not swing the binoculars by their
straps. They may hit someone and
cause injury. (Fig. 3)
• The soft case, strap, and external

due to aging and stain clothes. To
prevent this, check their condition
before each use, and consult with
the shop where you bought them if
such deterioration is found.

• If you use the rubber eyecups for a
long period of time, you may suffer
skin inflammation. If you develop
any symptoms, consult a doctor
immediately.
• Be careful not to pinch your finger
when adjusting interpupillary
distance or diopter. Be particularly
careful if you let small children use
the binoculars. (Fig. 4)
• Do not leave the polyethylene bag
used for packaging within small
children’s reach. Children may put it
on their mouths and suffocate.
(Fig. 5)
• Be careful that small children do
not inadvertently swallow the cap or
eyecup. If it does happen, consult a
doctor immediately.
• Do not disassemble the binoculars.
Repairs should only be performed by
a trained engineer.

OPERATION AND CONTROLS
1. Do not open the right and left
binocular tubes beyond their
limits. Also be careful not to
rotate the diopter ring, focusing
ring beyond their limits. (Fig. 7)
2. Avoid rain, water splashes,
sand and mud. (Fig. 8) With
waterproof binoculars, though
some rain or splashed water will
do no harm, wipe the water off as
soon as possible.
3. Always protect binoculars from
shock. If you cannot obtain a
normal image after dropping or
getting the binoculars wet, take
them immediately to the shop
where you purchased them.
(Fig. 9)
4. When exposed to sudden
temperature changes, water
condensation may occur on lens
surfaces. In this case, thoroughly
dry the binoculars at room
temperature.

STORAGE
5. Water condensation or mold may
occur on lens surfaces because
of high humidity. Therefore, store
the binoculars in a cool, dry place.
After use on a rainy day or at
night, thoroughly dry them at room
temperature, then store in a cool,
dry place.
6. For lengthy storage, keep
binoculars in a plastic bag or an
airtight container with a desiccant. If
this is not possible, store in a clean,
well-ventilated place, separate from
the case, as they are easily affected
by moisture. (Fig. 10)
7. Do not leave the binoculars in a car
on a hot or sunny day, or near heat
generating equipment. This may
damage or negatively affect them.

MAINTENANCE & STORAGE
8. After having removed dust with a blower, clean the body surface using
a soft, clean cloth. After use at the seaside, lightly soak a soft, clean
cloth with water and wipe off salt that may be on the body surface.
Then wipe the body surface with a dry cloth. Do not use benzene,
thinner, or other organic agents. (Fig. 12)
9. When removing dust on the lens surface, use a soft oil-free brush.
10.When removing stains or smudges like fingerprints, from the lens
surfaces, wipe the lenses very gently with a soft clean cotton cloth or
quality oil-free lens tissue. Use a small quantity of pure alcohol (not
denatured) to wipe stubborn smudges. Do not use velvet cloth or
ordinary tissue, as it may scratch the lens surface. Once the cloth has
been used for cleaning the body, it should not be used again for the
lens surface. (Fig. 13)
11.Remove dust trapped in the focusing unit, diopter adjustment unit, or
other rotating parts with a soft brush.

Interpupillary adjustment
While looking at a subject through the eyepieces,
gently rotate the binocular body (a shown above)
so that the two circular viewnders become one
(as shown below).
You can adjust the two circular viewnders into
one even when the image is out of focus.
If the vieweld images are as shown above, the
optical axis has shifted.
If your eyes become tired or you see two images
for one target, it is recommended that you get
your binoculars inspected.
Optical axis: The direction of the eyepiece
tube (optical center).
With binoculars, the optical centers of right
and left tubes need to align.

Conguration
①Focusing ring
Can be pulled out in two steps by clickstops.
②Diopter adjustment ring
Usually, this ring is covered by the focus ring.
It is made operable by pulling out the focusing ring.
Position and functions
Position Ⅰ: Pushed into the deepest (Focusing) position.
Focusing ring can be used.
Position Ⅱ: Middle click (Unlocked) position (when the focusing
ring is pulled out one step).
Focus-lock status is established. Focusing ring
rotates freely.
Position Ⅲ: Fully pulled-out (Diopter adjustment) position
(focusing ring is pulled out two steps).
Focusing ring rotates freely.
Diopter adjustment ring becomes operable.

14
Diopter adjustment adjusts the balance of right and left eyesight.
If more than one viewer uses the same binoculars, adjustment is
necessary when a different person uses it.
If binoculars are used by one person only, readjustment of the
diopter is unnecessary after it has been initially adjusted.
1 Push the focusing ring ①in and look into the left eyecup with
the left eye.
Then focus on a distant object by rotating the focusing ring ①.
2 Pull out the focusing ring ①two steps so that the diopter
adjustment ring ②becomes operable.
3 Look into the right eyecup with the right eye, then focus with the
right eye on the same target while rotating the diopter ring ②.
4 Check focusing on both eyes <Conrmation of diopter
adjustment>.
5 When in focus, push the focusing ring ①in to lock the diopter
ring ②.

Diopter Adjustment
6 When the subject changes, refocus the new subject by rotating
the focusing ring ①.
・Rotate clockwise to focus on a more distant subject.
・Rotate counterclockwise to focus on a closer subject.
7 When focusing is not necessary, set the focusing ring ①in
the middle position (unlocked), so that it doesn't change the
focusing position even if you accidentally touch it.

16
Adjusting an eyecup's position
(As viewed from the eyepiece side)
Turn eyecup counterclockwise to
extend.
Turn eyecup clockwise to retract.
●Non-eyeglass wearers:
Extend the eyecup for use (third
click position).
Note: Do not rotate eyecups
beyond the third click position as
they may detach.
(42mm only)
Note: There are two click positions
before reaching the fully extended
position.
Position where vision is most
accurate and comfortable for your
use.
●Eyeglass wearers:
Use with the eyecups in their fully
retracted position.
If a wide, accurate view can be
obtained, you can also use the
middle click position.
Fully retracted position Fully extended position

Adjusting an eyecup's position
Horn-shaped rubber eyecups
●Cannot be used with eyeglasses.
Please take off your eyeglasses
before use.
●The horn-shaped rubber eyecups
are attached by covering the rubber
eyepieces.
●Adjust the horns of the eyecups to
match your temples by observing
the following points:
・
Match the distance between right
and left eyepiece tubes with your
interpupillary distance by moving
the tubes further apart or closer
together.
・
Set the eyecups to the fully
retracted position.
・
When mounting the eyecups, be
careful not to change their length.
