NIGHT VISION

INSTRUCTIONS

Lit. #: 06-2000/03-01

Remove the lens cap from the Illuminator.

Adjust the beam of the Illuminator to focus on the object under observation.

Using The Power Button And Illuminator

Never turn the scope on in daylight conditions with the lens cap off. The pinhole in the lens cap allows you to test the scope in daylight conditions. (The lens cap for model 26-4366 does not contain a pinhole).

• Model 26-4366 includes a special

Power Button

Aperture Setting Control feature. This allows the user to reduce the brightness of the image by adjusting the Brightness Control Ring. Therefore, the user can use model 26-4366 in daylight conditions with the lens cap off as long as the brightness control is at the lowest setting.

To use the scope and Illuminator, depress and hold the Power Button.

After you release the Power Button, the image will slowly fade out. This is normal and is not a defect.

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, allowing you to see in dark conditions too dark for the naked eye.

To Focus

First, turn the Objective Lens Focusing Ring to infinity. (Full clockwise as shown in the drawing).

While looking at a distant object (at least 36 ft. away), adjust the Eyepiece Focusing Ring for the sharpest image.

Once the Eyepiece Focusing Ring is adjusted, you need only adjust the Objective Lens Focusing Ring as needed.

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.

Spots In The Image

You may see spots in the image. These vary from scope to scope and are cosmetic blemishes inside the scope. These are normal for Night Vision Scopes and are NOT a defect.

TROUBLESHOOTING

Scope will not turn on.

GETTING STARTED

Installing Batteries

With a screwdriver, unscrew the battery compartment cover.

Insert two AA batteries into the compartment according to the + and

Image is not focused.

Adjust the focus on the Focusing Eyepiece. Adjust the Objective Lens Focusing Ring. For a focused image, you must be a certain distance from the object you are viewing. Refer to the following chart for the recommended minimum viewing range. 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.
