HOW Digital Night Vision Works

Congratulations on the purchase of your Tasco® Digital Color Night Vision. Comprised of high quality electronics and optics, this Tasco Night Vision unit is a hand-held digital night vision viewing system that utilizes a low-light charge coupled device (CCD) sensor providing images comparable to analog "Gen 2" resolution. Day and Night time images are magnified and displayed on a Color LCD micro display screen, which provides a color image when ambient light conditions are high enough, and a desaturated color or neutral, monochrome image (not the typical "green screen" night vision) under lower ambient light conditions.

Tasco Digital Night Vision products collect existing light through the objective lens. The light is then processed through a highly sensitive CCD sensor and transferred to the micro liquid crystal display (color LCD). Images viewed on the LCD are magnified 3 times. An infrared illuminator provides a light source to enable viewing in total darkness.

The Tasco Digital Color Night Vision unit is ideal for camping, caving, scouting, maritime navigation, and observing wildlife under the veil of darkness, patrolling warehouses and similar surveillance operations where light is scarce.

OPERATING INSRUCTIONS

1. Slide the battery compartment door (2) open in the direction of the white arrow. Insert two CR123 batteries (3v lithium, not included) into the battery compartment. Be sure to observe the correct battery polarity, as shown on the left. The "+" end of the top battery should be facing out (towards the battery door), and the "-" end of the lower battery should be facing out.

2. Remove the front lens cover. When finished using the unit, replace the cover to protect the objective lens (1) and IR light (7).

3. Press the ON/OFF switch (3) to power the device on. A green LED light (4) indicates that the power is on. To extend battery life, the unit will normally turn off automatically after 2 minutes (if no buttons are pressed). To cancel this auto-off function, briefly press and release the IR switch (8) on the top of the unit. The power will then remain on until you turn it off manually with the ON/OFF switch. The orange light on the lower half of the power indicator light (4) will glow if the unit is in auto-off mode (default), and will turn off if you cancel the auto-off function. If the batteries become weak, the green power indicator LED will blink.

4. View through the eyepiece (5) and select an object to focus on.

5. To focus the image, first rotate the eyepiece rubber ring (5) until the edges of the LCD display appear sharp to your vision. Next, rotate the objective lens focus wheel (6) until the object is in focus and the view is clearest. At this point, the display focus (eyepiece ring) is set for your individual eyesight and will not require further adjustment when viewing objects at different

distances. When changing the viewing distance, simply rotate the main focus wheel (6) until the image is in focus.
