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.

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 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 h o l d the Power Button.

•

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

To Focus

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

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.

Check that the batteries are installed properly. Replace the batteries with new ones. Check the battery contacts to ensure they are clean and free of corrosion. Press and hold the power button firmly and completely.

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).

Model Magnification Objective Size Viewing Range (ft.)

26-2429 2.4x 29mm 1.1 - 300

26-3652 3.6x 52mm 12 - 350

26-4366 4.3x 66mm 16 - 450

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 batteries 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.

• Keep the optics clean. We recommend using a camera cleaner kit to clean the outside of the objective and eyepiece lenses. Follow the directions with the kit.

• Do not disassemble this product. Unauthorized disassembly not only voids the warranty but may also cause damage from the lack of special tools and techniques.
