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 one CR123 3-volt lithium battery. To install, unscrew the battery compartment cover (6) located near the objective lens. Insert the positive end of the battery into the battery compartment leaving the negative end facing out. Replace the battery cover carefully – do not over tighten.

Use and Testing

This device operates on one 3-volt CR123 lithium battery. 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 (2). The objective lens cap can be conveniently stored on the side of the unit while in use in darkness.(7)

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 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. This device can be mounted on any tripod with a 1/4" tripod socket (5).

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.
