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 p roducts amplify existing light, allowing you to see in dark conditions too dark for the naked eye.
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.
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.
Your Night Vision device is ideal for a variety of professional and recreational uses including the following:
•Wild Life Observation • Search and Rescue
•Astronomy • Security
•Boating / Marine Use • Property Management
•Police / Law Enforcement
GETTING STARTED
Installing Batteries
This device operates on two AA batteries. To install, remove the battery compartment cover located on the bottom of the unit. Insert the batteries into the battery compartment so that the (+) and negative (-) terminals of the batteries match the markings inside the compartment. Replace the battery cover.
Use and Testing
This device operates on two AA batteries. Make sure they have been installed according to the instructions above.
If you wish to test your night vision device in a lighted area, be sure the objective lens cap is covering the objective lens (1) prior to pressing the “ON” button (2). The objective lens cap has a pinhole opening to admit a small amount of light for testing purposes.
If testing or using the device in the dark, remove the objective lens cap and activate the device by pushing the “ON” button (2).
Your Night Vision device offers a Built-In Infrared Illuminator. This allows you to see in complete darkness where no ambient light source, such as moonlight, is available. To activate, simply press the button (3) located next to the “ON” button.

Direct the device at an object at a distance approximately 100 yards and rotate the eyepiece (4) to give the best quality image. After the adjusting, do not rotate the eyepiece any longer irrespective of the distance and other conditions.
Direct the device at the subject to be viewed and adjust the final focus by rotating the objective lens focusing ring until the image quality is optimal.
The Green LED indicates that the light amplifier unit is on. The Red LED indicates that the Infrared Illuminator is on. Always remember to turn the unit off when done. Do not store this device while the indicators are lit.
Caution: This device can be used in extreme cold weather. However, when the unit is brought back into a warm environment, you must wait approximately 5 hours before using the unit again. Damage may occur due to condensation that may have accumulated on the internal circuitry of the unit.
Spots In The Image
You may see spots in the image. These vary from device to device and are cosmetic blemishes inside the device. These are normal for Night Vision devices 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. Check that the power is in the “ON” position.
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.
Visibility decreases or disappears.
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.
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 enviro n m e n t s.
