Dear customer,
we are delighted that you have
chosen our SPECTRA binocular and
would like to thank you for trusting
in our products. It is important for
us to provide you with the best
product and if ever needed, the
best service support available so
that you can enjoy your outdoor
passion to the fullest.
Repairs should be solely handled by an authorized repair location
or GPO GmbH & Co. KG. The improper and unauthorized usage,
disassembly or repair of the products by non-authorized repair
business may result in the termination of this products warranty.

Please carefully read these safety instructions and follow
these guidelines when using this product.
Never look directly into the sun, bright light sources or
laser based light sources through your binocular. This
can cause irreparable eye damage. Optics in binoculars
function as a magnifying glass, therefore dramatically
increasing the intensity of the light source.
Store the binocular and all accessories included with
this product out of the reach of children. Some of our
products may contain small parts which could create a
choking hazard for small children, or nylon straps which
could create a strangulation hazard.
Be cautious when touching metal parts when the
product has been stationary and extensively exposed
to the sun or to freezing cold, as extremely hot or
extremely frozen metal components may cause an injury
to exposed skin.
After using this product, always use the protective covers
provided to avoid accidental light magnifying, which may
create a fire.
Avoid improper shock, such as dropping this product. It
is an optical instrument and damage may occur

Eyecup adjustment
The rotary eyecup has two break positions for different applica-
tions. The different break positions allow you to custom adjust
the distance between your eye and the ocular lens. This beneficial
feature allows you to be able to adjust the eye distance to your
personal preferences. This adjustment creates additional benefits
for use with and without eye glasses.
Use without glasses:
Most frequently, users not wearing
eyeglasses will need to adjust the
rotary eyecup completely up. Twist
the eyecup counterclockwise until the
eyecup is fully extended. Users not
wearing eyeglasses may also find the
full field of view more comfortable
with the eyecup slightly rotated
down. For this purpose, there are
additional break positions for your
use and your personal preference.
Use with glasses:
Most frequently, users wearing eye-
glasses will need to adjust the rotary
eyecups completely down. Twist the
eyecups clockwise.

Adjustment of the interpupillary
distance (ipd)
Interpupillary distance (IPD) is the distance between the center of
the pupils of the two eyes. For a full “field of view”, the IPD of the
binocular must be adjusted to match the IPD of the user. This can
be accomplished by simply opening or closing (buckling) the center
hinge of both binocular halves while looking through the binocular.
The IPD adjustment is correct when you can see a clear single
circular picture with both eyes open.

Adjustment of the diopter
since most users have a minor visual acuity difference between
their left eye and right eye, the diopter is an adjustment feature
that allows the user to custom focus each side of the binocular to
the correct vision of each eye. To compensate for possible imbal-
ances of the vision between both eyes, you can adjust this binocu-
lar to your individual needs. The diopter adjustment ring is located
on the right ocular below the eyecups. Make sure the interpupillary
distance (IPD) is adjusted correctly. See instruction above.
Make sure the interpupillary distance (IPD) is adjusted correctly.
See instruction above.
Select an object to be viewed at a distance of more than 20 meters
(appx 20 yards).
Cover or close your RIGHT eye.
Using the center focus wheel,
focus your LEFT eye on your
selected object until the picture
is sharp.

Cover or close your LEFT eye. Using the diopter adjustment ring, focus
your RIGHT eye on your selected object until the picture is sharp.
Your binocular is now adjusted to your personal visual acuity in
each eye. The diopter is locked in place and will not need further
adjustment. You can now view any object at any distance by
using the center focus wheel.

Care, cleaning and maintenance
You can clean the optics of your product with the optical
micro-fiber cleaning cloth provided with your product, or by using
other lens cleaning equipment solely intended for optical cleaning
purposes.
Be sure to keep the optical surfaces clean and immediately remove
any dirt or oil debris caused by grease (finger prints), oil or water
spots to guarantee consistent optical quality.
To clean the exterior lenses of your product, be sure to first remove
any granular dirt or debris that may cause scratching during the
cleaning process. Be aware that rough granular dirt particles must
be removed with either an air bellows or a clean hair brush. Other-
wise, this may lead to damage of the optical coating or scratches
on your lens. Once large debris is removed, slightly breath onto
the optical surfaces to create a damp fog, then use the dry optical
cleaning micro-fiber cloth provided to clean the lens surfaces. All
other outside mechanical parts, as well as the rubber armor, can be
cleaned with a normal soft, clean and slightly damp cloth. Please
do not use the optical cleaning micro-fiber cloth to clean the out-
side parts or the rubber armor. This micro-fiber cloth must remain
free of any physical granular debris.

Proper strorage
After using the binocular it is recommended to store it dry, in the
case that came with your product, in a well-ventilated room, at
normal to low humidity levels, in normal room temperatures.
If you use your product in a region with high humidity, store your
product in an airtight container with a humidity absorption aid to
avoid any exterior fungus adhesion
Spare parts
If you need spare parts or accessories for your binocular, please
contact an authorized dealer or GPO GmbH & Co. KG.
