Overview, Troubleshooting, Operation at Night

2. OVERVIEW

The night vision binocular BN 5 is observational optico- electronic device, intended for examining objects and orientation at nighttime or under dark conditions. The unit utilizes 2 (two) image intensifiers which amplify available moonlight, starlight or man-made light. The binocular was designed to be easy to use, and provide many years of operation.

Some of the typical activities where the BN 5 Night Vision Binocular can be useful:

•law enforcement

•wildlife observation

•security

•search and rescue

•hunting

Features

•Built-in infrared illuminator allows observations in total darkness (i.e. basement, cave or dark room);

•2 (two) image intensifiers, one for each eye; provide stereo vision;

•Independently adjustable eyepieces;

•Interpupilary distance adjustment;

•Lightweight and comfortable;

•Soft rubberized eyepieces make the viewing more comfortable;

•Water-resistant

•Works on standard AA batteries.

6.3 Operation at Night

Take off the lens covers (7) from the lenses (6). Turn on the device by pushing and holding the “On” button (4). In case of insufficient lighting when observing an object which is situated not far from the viewer, turn on the infrared illuminator by pushing and holding the button (3). As soon as the “I/R On” button is released the infrared illuminator turns off.

Note: The illuminator will be activated only if the unit has been already switched on by the button (4).

Note: If you look directly at front of the binocular when infrared illuminator is on it appears as a red dot at a size of a lit cigarette. The illuminator can be also detected using night vision device. Therefore, if you need to remain undetected, use the illuminator with caution.

Note: The unit automatically turns off after few minutes. This feature can be used to economically utilize the batteries power by periodically switching on and off the device during operation.

If brightness of the screen decreases, replace the batteries. Put protective lens caps back on the lenses after operation. If you don’t intend to use the device during long time remove the batteries from the battery compartments to avoid any damage of the device in case of occasional leakage of electrolyte from the batteries.

7. TROUBLESHOOTING

The binocular does not work.

Check if the battery is installed properly.

Check the charge of the battery. Replace if it is weak.

The image does not appear in focus.

Bring the inspected object to the center of the image. Turning the eyepieces (5) adjust to achieve the clearest image on the screen. Repeat the steps of focusing if necessary
