GENERAL INFORMA T ION ABOUT
How does my LOMO® Night Vision Device Work?
Night Vision Scopes are sophisticated opto-electronic devices that assist viewing in near or complete darkness by amplifying all available light. Unlike telescopes and binoculars, they are usually not intended for magnification of remote objects. All LOMO® Night Vision Devices include a built-in Infrared (IR) Illuminator that provides additional light, making it possible to see in complete darkness. A small red dot appears on the front of the Night Vision Device when the IR Illuminator is ON.

LOMO® NIGHT VISION DEVICES & FAQs
When using a Night Vision Device, you are actually looking at an image that is projected by the intensifier tube located inside the unit (Fig. 1). Light enters the Night Vision Device through the objective lens and hits the photocathode in front of the intensifier tube. Highenergy electrons produced by the photocathode create an image on the phosphor screen located on the back of the tube. This brighter image is projected through the eyepiece to the user's eye. The amount of light gain produced by the tube determines the brightness and clarity of the viewed image (15,000 to 40,000 times).

When do I use my LOMO® Night Vision Device?
You can use your Device any time when it is "too dark" for your naked eyes to see: for example, at night, during twilight, power outages, in the darkroom, basement, cave, etc. You can even simulate "night" during the day ­ each Device comes with a lens cover that is equipped with a pinhole for daytime observation. Besides protecting the optics from scratches and dust, it protects the Device from overexposure to bright light that can be harmful to the intensifier tube inside.

DO NOT operate your Device in bright light conditions such as sunlight, electric light, etc., without the protective lens cover. DO NOT point your Device at any bright light sources, such as campfires, headlights, etc. Exposure to bright light can shorten the life of your Device and possibly cause permanent damage to the intensifier tube. Such damage is not covered by your LOMO® Warranty!

How do I operate my LOMO® Night Vision Device?
The following steps are common to all LOMO® Night Vision Devices. For details specific to each Device, please refer to the corresponding pages.

5) Look through the Device and focus it.

Focusing: The focusing of all Night Vision Devices is completed in two steps (Fig. 2): Slowly rotate the knurled ring of the eyepiece (diopter) either direction until a sharp image of the grain is obtained. Slowly rotate the knurled ring of the objective lens either direction until the object you are observing appears in sharp focus. The objective lens will have to be readjusted for objects that are closer or further away.

1) Remove the Device from its case. 2) Install batteries.

Batteries: Devices require either AA or AAA type batteries. When installing, follow the polarity indicators on each Device. Use fresh batteries only. DO NOT mix different brands or types of batteries. Battery life will vary according to lighting conditions, which affect the rate of power consumption by your Device.

3) Turn the Device ON with the protective lens cover still attached to the objective lens. The image in the eyepiece will appear in fluorescent green. 4) Use common sense! If it's dark ­ remove the protective cover. If it's "too bright" ­ keep it on.

Fig. 2
6) If the image appears "too dark", turn ON the infrared (IR) illuminator. A red dot will become visible on the front of your Device. 7) Turn the Device OFF after use.

How far can I see with my LOMO® Night Vision Device ?
The effective viewing range of a Night Vision Device greatly depends on atmospheric conditions and the amount of available ambient light that can vary from "high" (full moon, street lights, etc.) to "low" (overcast) and "none" (total darkness). The following are the approximate viewing distances for LOMO Night Vision Devices under optimal conditions: clear night, full moon, high visibility: ElfTM-1, KentaurTM, ONVTM -- 50m/55 yards ChameleonTM (2.5x/4x), NVFlexTM (3x) -- 100m/110 yards ReconTM-2 -- 500m/550 yards Unfavorable atmospheric conditions such as fog, haze, etc., or a lack of ambient light may reduce the effective viewing distance of your Night Vision Device.

Other useful facts about LOMO® Night Vision Devices:

1) Black spots Spots in the field Central zone 1-3 of view are Boundary zone 3-5 normal, Periphery zone 5-10 and should not be considered an Fig. 3 imperfection ­ they are cosmetic blemishes in the image intensifier tube and do not affect the performance of your Device (Fig. 3). 2) A humming noise produced by the Device when functioning properly is normal. 3) After you have turned your Device for the field of view to retain its green several minutes. To make sure that the being drained, confirm that the power are in the OFF position. OFF, it is normal color for up to batteries are not and IR switches

How do I care for my LOMO® Night Vision Device ?
1) Store the Device in its original case with the lens caps on. Remove the batteries if the Device is not used for an extended period of time. 2) Protect the Device from shocks, vibrations, direct sunlight, dust, moisture and extreme temperatures. 3) Only clean the lenses with photographic quality cleaning materials . 4) Wipe the housing with a clean, soft cloth.

DO NOT attempt to service the Device yourself. DO NOT disassemble, except to remove and reinstall interchangeable objective lenses or eyepieces (ChameleonTM or NVFlexTM). Doing so will void your LOMO® Warranty!

What If I Need Help with my LOMO® Device? Before requesting help... Problem
The Device does not work when switched ON. No "green" in the eyepiece. The Device flashes with "green", especially after not being used for an extended period of time. The image is "too dark" or not in sharp focus.

Solution
Make sure that the batteries are installed correctly and are fresh. Reset the flash protection circuit by turning the Device OFF for 30 - 60 sec. Let the Device run with the flashes for 5-10 minutes. It is going through a de-gasing cycle and should resume normal operation shortly. Make sure that the batteries are fresh. Replace if necessary. Re-focus the Device (eyepiece first, objective second). Turn ON IR Illuminator.
