Up close to the eyepieces around the barrels are small screws that you can use to "collaminate" your binocs. The screws aren't meant to be accessed by the owner and most manufacturers cover them up with the material that surrounds the binocs. Of course the binocs in their current state are useless anyhow, so I wouldn't hesitate to peel up the material to look for the screws. If you do it carefully, you can reseat the material anyhow. Then once you locate the small screws, put the binocs on a stand or a table outside. Focus on something far away using one eye. Then using both eyes, you adjust the screw on the other eyepiece while looking through the binocs. Adjust until you get a single image. You can use loctite, or nail polish to "glue" the screw in the final position if it is really loose.

Assuming you are focussing correctly. When binoculars are out of collimation the most usual effect is double vision as the optical axis do not line up. The only thing you can do is to take them to a binocular repairer. The problem is the cost. Proper repair need the use of a device known as a collimator and it is a laborious task to do it properly. Your binoculars do not carry a high monetary value and a proper repair will cost more than a new binocular of similar specs. Porro prism binoculars mostly have the objective lenses set further apart than the eyepieces. This holds true except for reverse porro prisms which are the other way round. Roof prisms have both the front and rear lenses inline.
Make sure when you focus that the first eye you use to focus with is the one where the eyepiece does not have its own focus ring (dioptre). The dioptre adjustment is on either the left or the right depending on the brand. That eyepiece should be left alone until you have focused using the center ring. Then leave the center ring alone and focus the eyepiece that has the adjustment ring.

Go to; www.rugift.com. They are a dealer for this NV and they do have the user manuals.

Good luck. :)

Ask at http://manualfox.com/driver.htm
They will find any Vivitar driver!

you get this if you happen to drop the binocs. prism alignment disturbed. once adjusted will get single and sharp image.

You have to open each side ( nikon travelite covers just unclip ) to get to the 4 prisms. Once opened to clean make sure you do not break the glue that holds down the prisms ( move the prisms in their seats and your alignment is out ). Clean with window cleaner and isopropanol to finish.
