FOCUSING
To focus your Dark Strider Binoculars, perform the following steps:
1) Adjust the eye pieces (diopters). Turn the diopter adjustment rings clockwise until they stop. While
looking through the eyepieces, observe the scene and slowly begin turning the diopter adjustment
rings counterclockwise until the image becomes clear and sharp.
SETTING-UP PROCEDURES
To check device operation in daylight or in an illuminated room, observe the following procedures:
1) Verify that the battery is inserted into the battery compartment in accordance with polarity mark-
ings on the binoculars’ body.
2) Verify that the objective lenses and light sensor caps are securely closed.
3) Activate the unit by pushing the PWR button, but without removing the protective caps. While
looking through the eyepieces of your Dark Strider, observe the scene. Verify whether or not the green
light is indicating that correct IIT operation is occurring.
4) Adjust the interpupillary distance by putting the binocular in both hands and adjusting the bino
until you basically see one round image.
5) Adjust the eyepiece diopter rings until the images becomes clear and sharp.
6) Turn the unit OFF by pushing the PWR button. The green glow will disappear from the eyepieces.
7) Replace the objective lens caps securely over the objective lenses.
OPERATION IN NIGHTTIME CONDITIONS
CAUTION:
Avoid exposing the binoculars to bright light sources. Bright light emitted by fires, automobile
headlights, lanterns, projectors, etc. will cause serious damage your Dark Strider.
1) Visually estimate the illuminance level in the viewing area. Operation with the objective lens caps
off is safe when the illuminance level is less than 1 lux; at an illuminance level of 1 lux, you will barely
be able to read a newspaper, even after your eyes have adjusted to the low light conditions.
2) Remove the front lens caps.
3) Activate the unit by pushing the PWR button. A green light indicating correct IIT operation will ap-
pear after a momentary delay.
4) Observe the scene and focus your Dark Strider.
IR ILLUMINATOR OPERATION
CAUTION:
Do not forget that light emitted from the IR illuminator is invisible to the naked eye; however, it
can be easily detected when using night vision devices.
