[. . . ] HOW NIGHT VISION WORKS Bushnell Night Vision products collect and amplify existing light through the objective lens, which is then focused on the image intensifier. Inside the intensifier, a photocathode is "excited" by the light and converts the photon energy into electrons. These electrons accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a green monochrome TV screen) which emits an image that you can see. It is the acceleration of electrons, which provides gain and enhances the image. This is a Generation I device. Image is not focused. Adjust the focus on the Focusing Eyepiece. Adjust the Objective Lens Focusing Ring. For a focused image, you must be at least . 5 feet away from the object you are viewing. If still no improvement, clean the lenses; they may be foggy or dusty. (See To Focus). Visibility decreases or disappears. Bright light sources such as headlights may cause visibility to degrade or disappear completely. Release the Power Button and turn the scope away from the light source. The unit will restore itself in 1 or 2 minutes. Conditions such as fog or extremely dark environments will decrease visibility. Scope flashes. The scope may flash when used in a bright environment. It may also flash during the first few seconds of use in dark environments. CARE & MAINTENANCE · When not using for an extended amount of time, remove the battery and store the product in a dry location. · Avoid turning the product on in extremely bright light conditions. · Handle this product like you would a camera. Though Bushnell Night Vision products are durably constructed, the image intensifier tube consists of glass and is subject to breakage.
