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.
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, Astronomy, Boating / Marine Use, Police / Law Enforcement, Search
and Rescue, Security, and Property Management
GETTING STARTED
INSTALLING BATTERIES
This device operates on two AA Alkaline batteries. To install, remove the battery compartment cover
located on the bottom of the unit. Insert the batteries into the compartment so that the positive
(+) and negative (-) terminals of the batteries match the markings on the battery cover. Replace the
battery cover.

USE AND TESTING
This device operates on two AA batteries. Make sure it has 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.
Your Night Vision device offers a Built-In Infrared Illuminator (3). This allows you to see in complete
darkness where no ambient light source, such as moonlight, is available. To activate, simply press
the button (4) located next to the “ON” button.
Direct the device at an object at a distance approximately 100 yards and rotate the eyepiece (5) 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
(1) until the image quality is optimal.
The Green LED indicates that the unit is on (6). Always remember to turn the unit off when done.

This device can be mounted on any tripod with a ¼” tripod socket.
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.

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.

of use in dark environments.
