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.
