FLINQ FQC8340 - Operating Instructions; Eye Distance Adjustment; Focus Adjustment; Vision Compensation

EN Manual FlinQ HD Binocular
Adjust eye distance
Adust the center distance betwenn the left and right lens tubes to make the
images measured by the eyes overlap.
Focus adjustment
First, observe the target with the left eye, and turn the focusing hand
wheel(8) until the target observed by the left lens tube is clear.
Adjust vision compensation
Observe the target with the right eye, slightly turn the diopter wheel of the
right eye, and take the left lens tube as the reference until the left and right
lens tubes are equally clear.
Change the observation target
If the above adjustment remains unchanged, to change the observation
target, repeat steps 4-5 and turn the focusing handwheel.
FAQ
1.Can’t see the objects
Check if the direction of the telescope is reversed, if not, check whether the
magnication is low or high. For the rst use, it is recommended to start the
focus calibration at a low magnication, calibrate with a 5-10 meter target,
and then look into the distance when it is clear, or adjust to a high
magnication for observation.
2.The image is blurry
First check whether the lens of the telescope is clean. If the lens is ok, check
whether the focus is in place. When adjusting, move slowly, and pay attention
to avoid factors that aect the clarity of observation (see cautions).
3.Dizziness problem
The telescope lens is composed of optical lenses, which is equivalent to
putting several groups of lenses in front of the eyes. When viewing, the
telescop e will bring the picture closer to the eyes. Don’t watch it for too
long at the rst time, get used to it in 1-2 minutes to avoid visual fatigue
caused by prolonged use.
4.Vision problems
If you are short-sighted/far-sighted and wear glasses, you can take o the
glasses you wear and use telescope to watch the target (severe astigmatism
needs to wear glasses to watch).
5.Fogging problem
When the temperature dierence betwe en indoor and outdoor is relatively
large (or the prod uct is sto red and packaged from the south to the north),
when cold and hot air meet, a layer of fog will instantly form on the lens
after opening, which is normal. Put it in a ventilated place to dry or
wipe the lens before use.
About magnication
The telescope magnication is not as high as possible, and the normal
use magnication of a handheld telescope is between 7-10X. When the
magnication of the handheld telescope exceeds 10X, it is theoretically
recommended to use a tripod to ensure the stability of the picture.
Otherwise, the higher the magnication, the little shake of the hand will
greatly aect the stability of the picture, resulting in more shaking of the
image. Screen jitter is not good for observing the target, and it is easy to
cause visual fatigue and nausea.
