INSTRUCTION MANUAL
This instruction manual is in common between ATERA H12x30 and ATERA
H10x21 Binoculars with Vibration-Canceller. It describes the ATERA H12x30
mainly, but the same usage is applied for the ATERA H10x21.

Remove the eyepiece caps from the unit. When using the unit with your
eyeglasses worn, follow the instructions below. The fully field of view will be
obtained even if you use eyeglasses to look through.
Twist-up Rubber Eyecup (Available for H12x30 only.)
When look through the unit with eyeglasses worn, leave the eyecup at the
lowest position. When using the unit with the naked eye or wearing contact
lens, pull up the eyecup to secure the field of view. (Ref. Figure 7)
When storing the unit in the carry case, put back the eyecups to the lowest position.
Turn on the power switch. The vibration canceller starts activating and the
green power indicator will light.
Note
：
The unit may buzz and can slightly vibrate as you turn on the power, but it is
not a vibration canceller malfunction. The vibration ceases when the power
switch is securely set in place.
Auto Power off
The vibration cancellation function stops automatically (and the power indicator
goes off) in 5 minutes after turning on the unit. If you restart the vibration
canceller, turn off the unit and then turn on again.
While looking through the binocular with both eyes, adjust the interpupillary
distance between the space of the eyepieces so that the field of view can be seen
as one circle. Be sure to make the adjustments with a distant object.
Hold the part of the eyepieces with both hands when you adjust the interpupillary
distance. It allows you to make the adjustments smooth. (Ref. Figure 8)
Interpupillary Distance Adjustments
This is to adjust the distance between the two eyepieces to fit your eyes.
Inadequate interpupillary distance may result in eyestrain.

HOW TO USE

For diopter adjustments, find a distant object to look through. While looking
through the left eyepiece with the left eye, focus on the object by turning the
focusing wheel. (Ref. Figure 9)
Then, while looking through the right eyepiece with the right eye, focus on the
same object by turning the diopter ring.
It is convenient for you to remember the position of the diopter ring scale so
that you can set the diopter ring swiftly without repeating the above procedure
every time you use the binocular. (Ref. Figure 10)
Once you have brought the unit into focus with both eyes, you use the focusing
wheel only to focus on different objects. (Ref. Figure 11)
Diopter Adjustment
This is for those who have different eyesight in right and left eyes. The diopter
ring can compensate for the difference in the right and left eyesight.

Attaching the straps
Attach the supplied strap to the strap eyelet as illustrated. (Ref. Figure 12)
How to put the strap through the strap ring:
As shown in the diagram, straighten and press down the tip of the strap with
fingers. (Ref. Figure 13)
Next, move the strap ring so that the tip of the strap goes through the strap ring.
HOW TO USE
⑤
This binocular employs the vibration cancellation function that is called
gimbals control system. If sudden movement (such as moving downward the
binocular suddenly from its lateral position) happens during the vibration
canceller is in operation, it may spoil functioning correctly the vibration
canceller. If this is the case, turn off the power and then turn on again.

Insert the Batteries
Use the supplied two AAA batteries. (Provides
for checking purpose only)
Confirm the power switch is turned to the OFF
position. Pick up the both sides of the battery
cap by fingers to open as shown in the photo.
(Ref. Figure 1)
With checking the polarity of the batteries,
insert the batteries into the battery
compartment. (Ref. Figure 2)
Replace the battery cap as it was placed. (Ref.
Figure 3)

HOW TO USE
①
Make sure that the power switch is turned to
the ON position if you turn on the power.
(Ref. Figure 4)
The power indicator will light in green. (Ref.
Figure 5)
Turn the power switch to the OFF position if
you don't use the unit. (Ref. Figure 6)
Note:
If the power indicator (green light) blinks, the
batteries are being exhausted. If this is the
case, the vibration canceller may not work
properly. Replace the batteries with fresh ones.
