Congratulations on the purchase of your Bushnell Night Vision  
Product. Bushnell Night Vision products are comprised of high  
quality image intensifier tubes and optics. Bushnell Night Vision  
products amplify existing light, allow ing you to see in dark  
conditions too dark for the naked eye.  
Image is not focused.  
Adjust the focus on the Eyepiece (4). Adjust the Objective Lens Focusing Ring. If still  
no improvement, clean the lenses; they may be foggy or dusty.  
This rugged water-resistant night vision device uses advanced technology and fiber  
optic bundles to eliminate distortion thus providing excellent resolution, superior  
image quality, and a flat field of view.  
Visibility decreases or disappears.  
HOW NIGHT VISION WORKS  
Bright light sources such as headlights may cause visibility to degrade or disappear  
completely. Turn the Power OFF (2) 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.  
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.  
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.
