Newcon Optik DN483, DN482 Testing of operation in a daytime, Operation at night

recommended to use Alkaline batteries, which ensure the most stable performance.

b. Testing of operation in a daytime

During the bright time of the day:

Turn on the on/off switch (9). The lens cap (6) must be on. Direct the device at an object placed within 10-20 m from the viewer. Turn the focus knob (10) and eye-piece (3) try to achieve the sharpest image on the screen of the image tube.

NOTE: The device won’t burn out even if it is exposed to a bright light. The automatic shut-off system will make the screen dark. After replacing the device into dark environment the tube will recover in few seconds.

CAUTION!

The device is not supposed to be directed at a bright source of light: bright lamps, the sun, welding and etc – it may result in the reduction of the light gain of the device. In order to avoid the fatigue of photo-cathode it is not allowed to leave the active device motionless in the excessively bright environment (dawn, dusk, daylight, etc.) during more than 30 minutes.

c. Operation at night

AT MOON LIGHT: Take off the lens cover (6). Turn on the device-using switch (9). Turn the eyepiece (3) adjust to achieve the best shape of the reticle. The reticle brightness can be adjusted by switch (8). Then obtain the most clear-cut image of the object focusing with knob (10). Repeat the steps of focusing if necessary.

AT INSUFFICIENT AMBIENT ILLUMINATION: use the Infra/Red illuminator activated by rotating switch (9). Select one of three positions of the switch for different IR power settings (10, 25 or 75 mW). If brightness of the screen is decreasing, replace the batteries.

It’s recommended to take out the batteries during long periods of non-operation.

Do not forget to switch the device off after end of work!

8

(for example, .375 H&H Mag) your eye should be situated at the distance of 2-5cm from the edge of the Eyepiece Guard. The device should be located in the position which allows comfortable observation without stretching forward;

•Place inserts (4, 5) in the apertures of the rail (2). The insert (4) is placed with a pimple looking downwards in the nearest front slot of the rifle rail. If there is no such a slot, it’s recommended to make it at a gunsmith workshop.. It is recommended to place the inserts at the maximum possible distance from each other;

•Place clamps (6) and clamp screws (7) in the inserts (4, 5). Tighten screws (7) in order to obtain hard fixation. When necessary the excessive front part of the rail (3) can be removed.

Installation is completed and the device is ready for use as a hunting scope.

c. Variant III – side rail for East European (Warsaw Pact) rifles.

Side rail can be used for the installation of DN482/483 on a hunting rifle with side rail. The appearance of the device with a side rail is shown below:

It is recommended to contact NEWCON OPTIK for installation of the side rail.

ATTENTION! In case if you use other type of binding, to eliminate the phenomenon of shooting point displacement, device binding should be advised with Newcon Optik, because usually such displacement is caused by unqualified installation.
