5. OPERATION INSTRUCTIONS
WARNING! NEVER OPERATE YOUR NIGHT VISION DEVICE
IN DAYLIGHT AREAS WITHOUT THE LENS COVER ON!
NEVER DIRECT THE LENS IN THE DIRECTION OF BRIGHT
LIGHT!
Once in dark environment, take off the lens caps (4). Operation
without the lens cover on is admissible only at the illumination level of no
more than 1 lux (at this illumination one can read a newspaper text with
difficulty after 5-10 minutes of eyes’ adaptation = twilight and darker).
Check the functioning of the device by switching it on: squeeze activation
lever (5) and look through eyepiece (3). You should see a greenish-lit
screen. Rotate eyepiece (3) to achieve sharpest image. In order to focus
on a different distance, rotate the objective lens (2). If everything works,
now is a great time to fill the warranty card.
Proper operation of the activation lever: Push it down and hold in this
position. This should provide 30-60 seconds of operation (or more). Once
the screen begins to get dimmer boost the image by releasing the handle
and pushing it down again after a few seconds
(not immediately!).
Pumping the lever up and down rapidly is wrong! That will deactivate the
power mechanism. You will need to wait 15-30 minutes before activating
it again. Doing so repeatedly will cause irrecoverable damage to the
activation mechanism.
When conditions are very dark, use the AP 12 Infa Red illuminator (9).
Before usage, install a battery, observing the correct polarity.
6. CARE and MAINTENANCE
Maintenance includes only cleaning of parts if necessary.
6.1.Clean the lens and eyepiece optical surfaces with a soft cloth
dampened with “lens cleaner” obtained from any camera store. Clean the
lens surface carefully with circular movements starting from the center.
6.2.After a long period of use the brightness of the screen may decline
when actuating lever is pressed. To regain normal brightness you should
turn the pressure adjustment screw (7) a quarter (¼) of a turn clockwise.
To reach the adjustment screw (7), first remove the screw cover (6) and
the strap, than unscrew the bushing (8). This will expose an opening in
the housing, so one can reach the adjustment screw.
7. TROUBLESHOOTING
The scope does not work.
Squeeze the lever all the way. Do not release it
The image does not appear in focus.
Bring the inspected object to the center of the image. Turning the
eyepiece focusing (3) adjust to achieve the clearest image on the screen.
Then obtain the most clear-cut image of the object by rotating the front
lens (2). If the view still does not seem in focus, clean the lenses; they
could be foggy or dusty.
Unit flashes
It is normal for the unit to flash within the first 2 minutes of activation. If
the flashing continues afterwards the following is possible cause: bright
environment (even with the cap closed!)
