Operation
CAUTION! Do not use the device for direct beam viewing. Long-
term over-exposure may cause satiation of screen and decrease
of resolution or irreversible reduction of photocathode response.
1. Unscrew the lid (1) of the battery compartment and install
one AAA size battery into battery compartment, observing
the polarity.
2. Screw the handle (7) into the tripod thread ¼inches (10) in
body.
3. Unscrew the lens cover (9). To switch the unit on, press
button (2). "
NOTE: after switching off, the device continues to work some
minutes due to the accumulated power.
4. Rotate the ring (3) to focus the lens 1Х(F1.4/26mm). Rotate
ring (13) to focus the lens 2Х(F1.8/50mm). For adjustment of
diaphragm (12), tighten the screw (11), adjust the diaphragm
(12) and release the screw (11). Turn the ring (5) for eyepiece
focus adjustment.
5. When viewing in near-infrared range, use cut-off filter (4).
While viewing a reflected radiation, use metallic surface as a
reflector. Any paper surface absorbs the radiation greatly.
6. For "goggle" operation, place the IR viewer onto "dove
tail” (13) of face-mask and сlamp it with screw. Adjust the
position with fixing screws for the most convenient operation.
