Operation - ATN Night Spirit XT User Manual

OPERATION

Take the monocular out of the case.
Push the ON/OFF switch to turn the unit on. The protective lens cover shall be attached to
the lens. Do not turn the unit on in daytime without the protective lens cap on. You should see
green glow in the eyepiece.
Observe the scene and adjust the diopter for optimal image clarity.
You may now enter a dark environment or simply shut the lights off in order to darken the
room.
Next, remove the lens cap/daylight filter. Adjust the front lens focusing. You should not have to
readjust the diopter. Remember that focusing range starts from 3 m.
To turn the unit off, push the ON/OFF switch again.
FOCUSING
To focus the Night Spirit XT first you will
need to adjust the diopter. Simply turn
the diopter clockwise until it stops. Then,
while looking through the diopter at an
object, slowly turn the diopter back coun-
ter clockwise until the grain on the image
becomes sharp.
NOTE: We suggest that you focus the
diopter during daylight with the filter on.
Next focus the front lens until the image
and the grain become both sharp. When
you are in low-light conditions and the
daylight filter is off, you may focus the
front lens to receive sharp image, the
diopter should not be adjusted.
NOTE: The front lens should be readjusted as you view objects at different distances.
BUILT-IN INFRA-RED ILLUMINATOR
Infra-red illuminators, or IR illuminators, are
common to night vision. The IR light greatly
enhances the perfor-mance of the Night
Spirit XT while remaining almost invisible to
a naked eye.
To turn the built-in IR on, push the IR ON/
OFF switch. To turn the built-in IR off, push
the IR ON/OFF switch again.
It is important to remember that the IR illu-
minator is simply an infra-red light source,
and like any light source, it may loose its effectiveness over a great distance.
