BATTERY INSTALLATION
The ATN Night Spirit MP operates with one AA bat-
tery. To install the battery, unscrew the battery cap
(A). Than you may put the battery (B) observing the
polarity indications on the battery compartment
surface and screw the battery cap.
OPERATION
• Take the monocular out of the case.
• Rotate the operation knob from “OFF” position to “ON” position 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 focus-
ing. You should not have to readjust the diopter. Remember that focus-
ing range starts from 0.25 m.
• To turn the unit off, rotate the operation knob from “ON” to “OFF”
position.
FOCUSING
To focus the Night Spirit MP 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 counter 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 MP while remaining almost invis-
ible to a naked eye.
To turn the built-in IR on, draw and rotate the operation
knob to “IR” position.
It is important to remember that the IR illuminator is simply
an infra-red light source, and like any light source, it may
loose its effectiveness over a great distance.
